Serve TransUnion LLC: Delaware LLC Service in 35 States

As of 2026, TransUnion LLC is a Delaware-organized limited liability company headquartered at 555 W. Adams Street, Chicago, Illinois 60661 and the correct FCRA defendant for consumer credit-file matters. Corporation Service Company is the designated registered agent in 35 or more states. New York plaintiffs face a distinct path: no active TransUnion LLC foreign-LLC registration exists in New York.

TransUnion LLC is organized as a Delaware limited liability company — not a corporation — carrying FEIN 36-4262739 and Accurint LexID 0001-4878-7477. Established in 1977 and reorganized into LLC form in 1999, the entity has operated for 49 years in consumer credit data and credit-reporting services under NAICS code 561450, the designation that appears in every state foreign-LLC filing. Christopher Cartwright serves as President and Chief Executive Officer per the most recent Accurint employment record dated February 6, 2026. The publicly traded company TransUnion (NYSE: TRU) is a separate Delaware corporation listed on the New York Stock Exchange — it does not maintain consumer credit files, process consumer disputes, or furnish credit reports to creditors, landlords, or employers under the Fair Credit Reporting Act. Captioning a FCRA complaint to the NYSE-traded parent rather than to TransUnion LLC introduces a Rule 12(b)(6) motion before the case reaches any merits argument: the parent corporation did not engage in the credit-reporting conduct the FCRA governs, and service on the parent — however technically executed — does not confer jurisdiction over the entity that committed the alleged violations.

Corporation Service Company serves as the registered agent for TransUnion LLC in substantially every state where it holds an active foreign-LLC qualification. That single-vendor concentration means that address verification, agent-status confirmation, and service execution follow a consistent protocol regardless of the forum state — the same operational architecture that C T Corporation System provides for Experian Information Solutions, Inc. in its 41-state network. CSC’s public records portal provides real-time address confirmation for each state in TransUnion LLC’s active qualification footprint, and pre-dispatch portal verification is required before every service event. CSC has a documented pattern of updating internal address records without simultaneously amending the underlying state foreign-LLC filing — a stale-address dispatch produces a rejected return that restarts the FCRA service clock at the point the error occurred, with potential statute-of-limitations consequences in matters filed close to the § 1681p two-year discovery deadline.

This guide addresses one question with precision: where TransUnion LLC accepts service of process in each forum state where its foreign-LLC registration is active, and what procedural alternatives exist for plaintiffs in states where that registration has lapsed or was never obtained. The guide does not address the NYSE-traded parent TransUnion (TRU) as a litigation defendant, and it does not address service on TransUnion subsidiaries handling healthcare data, tenant screening, or alternative-data risk products — each carries an independent state registration and registered-agent designation. For New York state-court FCRA matters — the most common service-mechanics gap encountered in TransUnion LLC FCRA litigation — two paths replace the CPLR § 311 route that does not exist: NY LLC Law § 304 substituted service through the New York Department of State, and direct federal filing in SDNY or EDNY under 28 U.S.C. § 1331 with FRCP 4(h)(1)(B) service on CSC at any active-state address. A name on a consumer credit report is not a name on a Delaware LLC registration.

Undisputed Legal’s process servers maintain direct-dispatch relationships with Corporation Service Company offices in every state where TransUnion LLC holds an active foreign-LLC qualification. To order service on TransUnion LLC, call (800) 774-6922 or use the link below.

Which TransUnion Are You Trying to Serve?

The TransUnion entity family presents a service-routing problem that FCRA plaintiffs encounter at the caption stage: the publicly traded company whose name appears in consumer-facing communications is not the credit reporting agency whose conduct gave rise to the FCRA claim. TransUnion LLC is the operating entity that maintains consumer credit files, processes reinvestigation disputes under 15 U.S.C. § 1681i, and furnishes credit reports to creditors and landlords. TransUnion (NYSE: TRU) is the separately traded parent holding company — a Delaware corporation whose identity appears in investor relations materials, SEC filings, and financial press coverage, none of which establishes it as the litigation target for private FCRA claims. The caption-controls-service doctrine applies across the entire TransUnion family: the entity named in the caption is the entity that must be served, and service on a different — even closely affiliated — TransUnion entity does not satisfy that requirement.

TransUnion LLC vs. TransUnion (NYSE: TRU): The Suable Entity and the Financial Parent

The name “TransUnion” in a credit report header, a dispute acknowledgment letter, or a consumer credit monitoring communication refers to TransUnion LLC’s operations — not to the NYSE-listed holding company that owns the consumer credit bureau through intermediate holding entities. TransUnion (NYSE: TRU) is a Delaware corporation with ticker symbol TRU on the New York Stock Exchange; it is a financial parent, not a credit reporting agency, and it does not process consumer disputes, maintain credit files, or furnish consumer credit reports to creditors. A FCRA complaint captioned to “TransUnion” without the LLC designation, or captioned to “TransUnion, Inc.” or “TransUnion Corporation,” names an entity whose registration status either cannot be verified in Accurint as the FCRA defendant or identifies the publicly traded holding company rather than the operating LLC.

The service-routing consequence is categorical: TransUnion LLC is a Delaware-organized LLC with a current Delaware registered-agent designation at Corporation Service Company, 251 Little Falls Drive, Wilmington, Delaware 19808, and with active foreign-LLC qualifications in 35 or more states. The NYSE-traded parent carries no consumer credit bureau operations and no service-of-process relationship to the FCRA conduct alleged. A summons captioned “TransUnion (NYSE: TRU)” served on CSC at Wilmington is served on the registered agent for TransUnion LLC — not for the NYSE parent corporation — and the service return does not satisfy the statutory service requirement for the correct FCRA defendant as captioned.

Entity Disambiguation: Why Accurint Returns Multiple Results

Entity	Jurisdiction	Registered Agent	Service Status
TransUnion (NYSE: TRU)	Delaware corporation (separate holding company)	Not the CRA	NOT THE CRA — captioning to parent triggers Rule 12(b)(6)
TransUnion LLC	Delaware LLC; foreign-qualified in 35+ states	Corporation Service Company	PRIMARY TARGET — FCRA, credit-report disputes
TransUnion Healthcare, Inc.	Separately verified per matter	Separately verified	SUBSIDIARY — healthcare data revenue cycle only
TransUnion Risk and Alternative Data Solutions, Inc.	Separately verified per matter	Separately verified	SUBSIDIARY — risk/alt-data products only
TransUnion Rental Screening Solutions, Inc.	Separately verified per matter	Separately verified	SUBSIDIARY — tenant screening only
Innovis Data Solutions	Separate company (not TransUnion-affiliated)	Separately verified	NOT TRANSUNION — frequently conflated, never serve at TU address

TransUnion LLC has no active New York foreign-LLC qualification. New York service goes through the Department of State substituted-service path under LLC Law § 304 — not CPLR § 311.

The TransUnion-Innovis Confusion: An Unrelated Company

Innovis Data Solutions — sometimes described as the “fourth credit bureau” alongside Equifax, Experian, and TransUnion — is an entirely separate corporate entity with no affiliation to TransUnion LLC. Both companies operate in consumer data and credit reporting, but their corporate structures, registered agents, registered-agent addresses, and litigation service paths are independent. A pleading that names TransUnion LLC for conduct arising from Innovis data operations, or that attempts service on CSC at TransUnion LLC’s Delaware or Illinois registered-agent address for Innovis-related claims, produces both a caption defect and a rejected service return simultaneously. Innovis and TransUnion share a functional description — consumer data and credit bureau operations — but not a corporate identity, a registered agent, a service address, or a litigation profile. Pre-filing Accurint verification confirming which entity’s file, report, or dispute process generated the claim at issue is the mechanism that prevents this confusion at the caption stage, before service is attempted.

The Statutory Service Framework for TransUnion LLC

TransUnion LLC’s Delaware-LLC form creates a service framework that differs from the corporate service paths applicable to Experian Information Solutions, Inc. and Equifax Information Services LLC in one structural respect: the governing statute for service on a Delaware limited liability company is 6 Del. C. § 18-105, not 8 Del. C. § 321, which governs service on Delaware corporations. In foreign-qualified states, each state’s LLC service statute governs rather than its corporate service statute — an Ohio plaintiff suing TransUnion LLC in Ohio Common Pleas invokes Ohio’s LLC service authority, not Ohio’s corporate service authority. The practical operational result is the same — service on Corporation Service Company at the forum state’s registered-agent address — but the statutory citation on the return of service must reference the LLC service authority rather than the corporate authority, or the return is subject to a technical defect challenge.

Delaware Service: State of Organization

TransUnion LLC was organized as a Delaware limited liability company. Every Delaware LLC must designate a registered agent at the time of formation under 6 Del. C. § 18-104, and service of legal process on a Delaware LLC is governed by 6 Del. C. § 18-105, which authorizes service on the registered agent designated under § 18-104. For TransUnion LLC, that agent is Corporation Service Company at 251 Little Falls Drive, Wilmington, Delaware 19808. Address verification via the Delaware Secretary of State’s online entity search and the CSC public records portal is required before dispatch — CSC has updated its Wilmington addresses for various clients without immediate state-filing amendments, and a stale address dispatch to an incorrect suite produces a rejected return even at the correct street address.

When the registered agent cannot be served under 6 Del. C. § 18-105(a), service may be made on the Delaware Secretary of State at 401 Federal Street, Suite 4, Dover, Delaware 19901. The Secretary of State then forwards process to TransUnion LLC’s last known address on file — 555 W. Adams Street, Chicago, Illinois 60661-3614. This fallback path is available where CSC’s Wilmington office cannot accept service on a specific dispatch date. Delaware-domestic service under § 18-105 is available regardless of which U.S. forum state the underlying litigation is venued in — a New York plaintiff with a SDNY FCRA matter can serve TransUnion LLC in Delaware and satisfy FRCP 4(h)(1)(B) without invoking any state-specific registered-agent path, which is operationally significant given the New York foreign-LLC registration gap addressed in Section 5 of this guide.

Foreign-Qualified State Service: The CSC Network

In states where TransUnion LLC holds an active foreign-LLC qualification, service is made on Corporation Service Company at the registered-agent address on file with that state’s secretary of state or LLC filing authority. TransUnion LLC holds foreign-LLC qualifications in 35 or more states as of May 2026 Accurint verification, with CSC serving as the registered agent in substantially every active-status state. The statutory authority governing service on a foreign LLC varies by state but consistently authorizes service on the designated registered agent — Ohio R.C. § 1701.07 (via § 1705.05 for foreign LLCs), Illinois 805 ILCS 180/1-50, California CCP § 416.10, Georgia OCGA § 14-11-209, and equivalent LLC-specific authorities in each qualified forum state.

Active-status confirmation via the CSC public records portal is required in every qualified state before dispatch. A filing that showed TransUnion LLC as a foreign-LLC registrant in a given state as of a prior Accurint pull does not confirm that the registration remains active as of the dispatch date. TransUnion LLC’s registration has moved from active to inactive in several states without pro-active notification to the litigation side, and a dispatch to a CSC address in a state where TransUnion LLC’s registration has since lapsed produces a rejected-service return. The correct procedural response to an inactive-registration result is escalation to the ordering attorney with identification of the available alternative paths — Delaware § 18-105 direct service, forum-state substituted-service-through-secretary-of-state where authorized, or FRCP 4(h)(1)(B) federal venue with CSC service in an active state — not a force-send to the state-filing address.

Federal Service Under FRCP 4(h)(1)(B)

Federal court service on TransUnion LLC is governed by FRCP 4(h)(1)(B), which authorizes service on a domestic or foreign corporation — and by analogical application, an LLC — by delivering to “an officer, a managing or general agent, or any other agent authorized by appointment or by law to receive service of process.” Corporation Service Company qualifies as “any other agent authorized by appointment” by virtue of TransUnion LLC’s foreign-LLC registrations in every active-status state. The appointment is established by the state foreign-LLC filing itself — CSC’s designation as registered agent in that filing is the authorization. No additional federal-court-specific authorization is required beyond the existence of that registration.

The FRCP 4(h)(1)(B) path is the primary resolution mechanism for the New York service gap. A FCRA plaintiff filing in SDNY or EDNY does not need a New York registered agent for FRCP 4(h)(1)(B) service on TransUnion LLC. Service may be made at Corporation Service Company, 251 Little Falls Drive, Wilmington, Delaware 19808 (under TransUnion LLC’s Delaware domestic registration), or at any CSC address in a state where TransUnion LLC holds an active foreign-LLC qualification. Federal service is geographically portable across the entire CSC network; the New York foreign-LLC registration gap is procedurally irrelevant to FRCP 4(h)(1)(B) service from SDNY or EDNY.

Subpoena Service: FRCP 45 Records-Only vs. Litigation Subpoenas

Subpoena practice against TransUnion LLC bifurcates at the purpose of the subpoena. A subpoena duces tecum under FRCP 45 commanding production of a consumer’s TransUnion credit file — issued as a records-only production request — is routed through TransUnion LLC’s Consumer Dispute Center at P.O. Box 2000, Chester, Pennsylvania 19016. The physical operations facility is located at 2 Baldwin Place, Chester, Pennsylvania 19022. These are the records-custodian addresses where TransUnion LLC’s consumer file production team processes consumer file requests and dispute-related subpoenas. Service of a records-only FRCP 45 subpoena at a CSC registered-agent address reaches the wrong internal team — CSC forwards the document to TransUnion LLC’s legal department rather than its records-custodian group, and the records-custodian routing delay extends the production timeline.

A subpoena that commands a corporate-representative deposition or document production beyond the consumer’s own credit file follows the litigation-service path: Corporation Service Company at the registered-agent address in the forum state, the same address used for service of the summons and complaint. The distinction is functional: if the subpoena requests the consumer’s own file by account number, Social Security number, or date of birth — Chester, PA P.O. Box 2000. If the subpoena commands a corporate representative to testify or produce documents about TransUnion LLC’s internal dispute-handling systems or credit-file processes — CSC at the forum state’s registered-agent address. Two addresses, two functions, two different internal TransUnion LLC teams.

FCRA Litigation and Federal Court Service

The Fair Credit Reporting Act is the dominant federal statute governing TransUnion LLC’s litigation exposure. TransUnion LLC’s relationship to FCRA practice is distinguished from every other Big Three credit bureau defendant by one fact: the controlling Supreme Court precedent establishing Article III standing requirements for FCRA federal plaintiffs is captioned TransUnion LLC v. Ramirez. That decision names this entity as the defendant. No other Big Three credit bureau page on this site can make that claim, and the doctrinal consequences of that precedent shape every strategic standing decision in post-2021 FCRA federal litigation — including the standing analysis for each federal FCRA complaint filed against TransUnion LLC since June 2021.

The Fair Credit Reporting Act: Operative Provisions

The FCRA, codified at 15 U.S.C. § 1681 et seq., imposes duties on consumer reporting agencies — a category that includes TransUnion LLC as the entity that maintains and furnishes consumer credit files. Six provisions govern the majority of private FCRA claims against TransUnion LLC. Section 1681e(b) requires reasonable procedures to assure maximum possible accuracy of consumer report information. Section 1681i imposes a reinvestigation duty: when a consumer disputes the accuracy or completeness of information in a credit file, the CRA must conduct a reasonable reinvestigation within 30 days of receiving the dispute. Section 1681g requires the CRA to disclose to any consumer, on request, all information in the consumer’s file at the time of the request. Section 1681n creates liability for willful noncompliance, authorizing statutory damages of $100 to $1,000 per violation plus punitive damages and attorney’s fees. Section 1681o creates liability for negligent noncompliance, authorizing actual damages plus attorney’s fees. Section 1681p establishes the statute of limitations: two years from the date the plaintiff discovered the violation, or five years from the date of the violation, whichever is earlier.

Federal question jurisdiction under 28 U.S.C. § 1331 is the primary basis for FCRA claims filed in federal court. Concurrent jurisdiction under 15 U.S.C. § 1681p permits FCRA claims to be filed in state court as well; in states where TransUnion LLC holds an active foreign-LLC qualification, state-court FCRA service follows the LLC service statute in the forum state. New York state-court FCRA claims face the registration-gap problem addressed in Section 5 of this guide — CPLR § 311 requires an in-state registered agent that TransUnion LLC does not currently have.

TransUnion LLC v. Ramirez: The Article III Standing Decision Bearing This Entity’s Name

In TransUnion LLC v. Ramirez, 594 U.S. 413 (2021), the Supreme Court resolved the Article III standing question for FCRA class actions in a decision that named this credit bureau as the defendant. Justice Kavanaugh, writing for a 5-4 majority, held: “Only those plaintiffs who have been concretely harmed by a defendant’s statutory violation may sue that private defendant over that violation in federal court.” The facts involved 8,185 class members whose TransUnion LLC credit files contained inaccurate OFAC-watchlist information that falsely linked them to terrorist and drug-trafficking organizations. The class prevailed at trial on damages of approximately $60 million. On certiorari, the Court found that only 1,853 of the 8,185 class members — those whose inaccurate OFAC information had actually been disseminated to third-party businesses during the class period — had Article III standing to sue in federal court. The remaining 6,332 class members, whose inaccurate OFAC information existed in internal TransUnion LLC files but had not been shared with any third party, lacked standing despite the § 1681e(b) statutory violation in their files.

The operational rule for FCRA plaintiffs filing against TransUnion LLC in federal court post-Ramirez: concrete harm, not bare statutory violation, is required for Article III standing. A complaint alleging inaccuracy in a TransUnion LLC credit file without alleging that the inaccurate information was disseminated to a third-party creditor, employer, or landlord — resulting in a denial of credit, employment, or housing, an identifiable monetary harm, or a reputational injury traceable to the disclosure — does not establish standing under Ramirez, regardless of how clear and how serious the § 1681e(b) accuracy failure was. The standing defect is not correctable by amendment if the underlying facts do not include third-party dissemination; counsel must evaluate the dissemination record before filing, not after the first dispositive motion. Ramirez is the controlling precedent. TransUnion LLC is the named defendant. Every strategic standing decision in post-2021 federal FCRA litigation against TransUnion LLC is measured against this case.

Spokeo v. Robins: The Analytical Foundation

In Spokeo, Inc. v. Robins, 578 U.S. 330 (2016), the Supreme Court established the framework that Ramirez applied five years later. Spokeo held that Article III standing requires a “concrete and particularized” injury — a bare procedural violation, without more, does not automatically confer standing merely because Congress provided a statutory remedy. The Court in Spokeo acknowledged that intangible injuries can qualify as concrete harms when they bear a close relationship to harms traditionally recognized in law — including reputational injuries, denial of economic opportunity, and disclosure of false information to third parties. The Court remanded for application of the concrete-harm standard rather than resolving it, leaving the question open for circuit courts. Ramirez applied Spokeo to the FCRA consumer-reporting context and resolved the open question: dissemination of the inaccurate information to a third party is the concrete-harm trigger; non-dissemination, however inaccurate the underlying file, does not satisfy it.

Circuit Precedent in TransUnion LLC Matters

The Northern District of Illinois is TransUnion LLC’s home district — the forum where its Chicago headquarters are located and where its litigation counsel and dispute-handling operational team are based. The Seventh Circuit therefore carries the greatest volume of TransUnion LLC-specific FCRA reinvestigation precedent. Seventh Circuit § 1681i jurisprudence addresses the specific operational practices of TransUnion LLC’s Chicago-based disputes team, and the Seventh Circuit has developed a body of holdings on what constitutes a “reasonable” reinvestigation under § 1681i in the context of TransUnion LLC’s dispute-processing workflow. Plaintiffs filing FCRA claims against TransUnion LLC in the Northern District of Illinois should research current Seventh Circuit § 1681i opinions before filing — circuit-specific reinvestigation standards for TransUnion LLC differ in procedural detail from standards developed in circuits where Experian Information Solutions, Inc.’s California-based disputes operations are at issue.

The Ninth Circuit, which carries the greatest overall volume of FCRA appellate precedent, addressed TransUnion LLC directly in the class-certification and standing phase of Ramirez before the Supreme Court reversed. The Ninth Circuit’s original class-certification holding in Ramirez was the position the Supreme Court overturned; post-Ramirez Ninth Circuit FCRA standing doctrine has been narrowed materially on the concrete-harm requirement. Counsel relying on pre-Ramirez Ninth Circuit class-certification opinions for standing analysis in TransUnion LLC federal matters should verify current circuit authority before filing, as the Supreme Court’s reversal on standing eliminated the pre-Ramirez Ninth Circuit class-wide standing analysis for inaccurate-but-undisseminated FCRA claims.

The New York Service Problem

TransUnion LLC presents a service-mechanics gap in New York that distinguishes it from every other Big Three credit bureau: its New York foreign-LLC registration is inactive. The legacy filing that appears in Accurint under the name “TRANS UNION CORPORATION” is not an active registration for TransUnion LLC, and the historical dissolution or inactivation of that filing means there is no currently authorized New York registered agent for TransUnion LLC. A process server dispatched to any New York CSC office on a CPLR § 311 service assignment for TransUnion LLC returns rejected — not because the service was procedurally defective, but because no New York-appointed registered agent for TransUnion LLC exists to be served.

Why CPLR § 311 Does Not Apply

CPLR § 311(a)(1) authorizes service on a corporation by delivering the summons and complaint “to an officer, director, managing or general agent, or cashier or assistant cashier or to any other agent authorized by appointment or by law to receive service.” The critical requirement is an “agent authorized by appointment or by law” — for a foreign LLC doing business in New York, that agent is the foreign-LLC registered agent designated in the New York foreign-LLC filing with the New York Department of State. TransUnion LLC’s New York foreign-LLC filing is inactive as of May 2026 Accurint verification. An inactive filing means the registered-agent designation in that filing is no longer operative under New York law. There is no current TransUnion-LLC-appointed agent in New York authorized to accept CPLR § 311 service. Attempting CPLR § 311 service on TransUnion LLC at a New York CSC office — relying on CSC’s general presence in New York without confirming that CSC holds an active TransUnion LLC New York registration — produces a rejected return and restarts the service clock, with potential statute-of-limitations exposure.

NY LLC Law § 304: Substituted Service Through the Department of State

New York Limited Liability Company Law § 304 provides the statutory remedy for service on a foreign LLC doing business in New York without an active registered agent in the state. Under LLCL § 304, service on an unauthorized foreign LLC may be effected by service on the New York Secretary of State as agent for the LLC. Service address: New York Department of State, Division of Corporations, One Commerce Plaza, 99 Washington Avenue, Albany, New York 12231-0001. The Department of State charges a service fee — verify the current fee schedule on the DOS website before dispatch, as fees are subject to change by regulation. Upon acceptance of service and payment of the fee, the Department forwards process to the LLC’s address on file, which for TransUnion LLC would be its principal office at 555 W. Adams Street, Chicago, Illinois 60661-3614.

LLCL § 304 substituted service is a two-step mechanism. The legal trigger is delivery to and acceptance by the Department of State, not TransUnion LLC’s receipt of the forwarded papers in Chicago. Service is complete under New York law when the Department of State accepts the process, not when TransUnion LLC acknowledges receipt. A plaintiff who effects LLCL § 304 service should retain the Department of State’s filed-document stamp, the fee receipt, and the certified mail return card confirming the Department’s forwarding to Chicago — these documents constitute the proof-of-service record for New York state court FCRA matters and must accompany any affidavit of service filed in the state court docket.

Federal Removal and Diversity Jurisdiction Considerations

TransUnion LLC, as a Delaware-organized LLC, is a citizen for diversity purposes of every state in which its members are citizens. Because LLCs take the citizenship of all their members under 28 U.S.C. § 1332, diversity jurisdiction for TransUnion LLC matters depends on the citizenship of each member — a determination that may require jurisdictional discovery if TransUnion LLC’s membership structure is not publicly available. Plaintiffs asserting state-law FCRA-analog claims in New York state court against TransUnion LLC should anticipate a removal notice under either diversity jurisdiction or federal question jurisdiction under 28 U.S.C. § 1331, as federal-question FCRA claims are removable. Removal to SDNY or EDNY resolves the New York registered-agent problem by moving the case to federal court where FRCP 4(h)(1)(B) service on CSC at any active-state address is available.

SDNY and EDNY Direct Federal Filing: Bypassing the NY Service Gap

For New York-resident FCRA plaintiffs, filing directly in the Southern District of New York or Eastern District of New York under 28 U.S.C. § 1331 (federal question) and 15 U.S.C. § 1681p (concurrent federal court jurisdiction) bypasses the New York foreign-LLC registration gap from the outset. FRCP 4(h)(1)(B) service is not limited to the forum state’s registered-agent addresses — a SDNY FCRA plaintiff may serve TransUnion LLC at Corporation Service Company, 251 Little Falls Drive, Wilmington, Delaware 19808, or at CSC’s registered-agent address in any state where TransUnion LLC holds an active foreign-LLC qualification. The return of service identifies the CSC address used and the statutory authority — FRCP 4(h)(1)(B) — and is filed in the SDNY or EDNY CM/ECF docket. The New York foreign-LLC registration gap is irrelevant to FRCP 4(h)(1)(B) service from federal venues in the Southern or Eastern District of New York.

Where to Serve TransUnion LLC

TransUnion LLC maintains active foreign-LLC qualifications in 35 or more U.S. states as of May 2026 Accurint verification. Corporation Service Company is the registered agent in substantially every active-status state. The sections below identify verified service addresses for thirteen key states drawn from May 2026 Accurint Corporation Filings, the operational rules for service at TransUnion LLC’s principal executive office at 555 W. Adams Street, Chicago, and the distinction between litigation service of process and consumer-file records requests routed through the Consumer Dispute Center in Chester, Pennsylvania.

The Corporation Service Company Service Network

Corporation Service Company’s single-vendor presence across TransUnion LLC’s active foreign-LLC states means that multi-state FCRA matters and nationwide class-action dispatches use the same agent-type, the same acceptance protocol, and the same pre-dispatch verification procedure regardless of forum state. The CSC public records portal — under two minutes per lookup — retrieves the current active address for TransUnion LLC in the forum state and catches any divergence from the state-filing address before the document leaves the office. Suite-level address specificity is critical: CSC co-locates registered-agent services for multiple clients in shared commercial facilities, and a suite-number error produces a rejected return even when the street address is correct. The thirteen addresses below are drawn from May 2026 Accurint Comprehensive Business Report filings; pre-dispatch portal verification is required before each dispatch regardless of this list.

Headquarters Service at 555 W. Adams Street, Chicago

TransUnion LLC’s principal executive office is located at 555 W. Adams Street, Chicago, Illinois 60661-3614, Cook County. This address appears in Accurint records under FEIN 36-4262739 and LexID 0001-4878-7477, in CFPB correspondence, and in consumer-facing TransUnion communications. It is not the registered-agent address for state-court service of process in Illinois. Illinois 805 ILCS 180/1-50 requires service on the designated registered agent. Illinois Corporation Service Company at 801 Adlai Stevenson Drive, Springfield, Illinois 62703-4261 is TransUnion LLC’s designated agent in Illinois. A process server dispatched to 555 W. Adams Street for ILCS 180/1-50 state-court service delivers to TransUnion LLC’s headquarters reception, which is not authorized to accept state-court process — the resulting return is challenged as insufficient service, and the service clock restarts. Federal FRCP 4(h)(1)(B) service at 555 W. Adams Street is permitted, but requires delivery to an officer, managing agent, or general agent — delivery to a lobby or reception desk does not satisfy FRCP 4(h)(1)(B). Illinois state-court service uses the Springfield CSC address; federal service may use either the Springfield CSC address or 555 W. Adams Street with officer/managing-agent delivery confirmation.

Chester, Pennsylvania: Consumer Dispute Center vs. Litigation Service

TransUnion LLC’s Consumer Dispute Center is located at 2 Baldwin Place, Chester, Pennsylvania 19022, with a mailing address of P.O. Box 2000, Chester, Pennsylvania 19016. This is the records-custodian address for FRCP 45 records-only subpoenas commanding production of a consumer’s TransUnion credit file by account number, Social Security number, or date of birth. A records-only subpoena delivered to P.O. Box 2000 Chester reaches the TransUnion LLC consumer file production team and follows the correct operational routing. Litigation process — a summons and complaint, or a litigation subpoena commanding a corporate-representative deposition or document production beyond the consumer’s own credit file — served at P.O. Box 2000 Chester reaches the records-custodian team, not TransUnion LLC’s legal department, and generates a failure-to-appear or failure-to-respond result. CSC at the forum state’s registered-agent address is the correct service point for all litigation process and litigation-related subpoenas.

Scope of Services — What Undisputed Legal Does and Does Not Do

Undisputed Legal delivers legal documents to the designated service target for TransUnion LLC — registered agent, principal executive officer, or state-of-organization service address — per applicable federal or state service rules. UL documents every service event with GPS-verified affidavits including device-coordinate timestamps and photo documentation of the CSC professional-desk acceptance interaction. UL confirms receipt by the designated recipient through return-of-service mechanics and records the agent’s name, role, time, and jurisdiction. UL coordinates multi-state dispatches across the Corporation Service Company network when a matter requires simultaneous service in multiple jurisdictions. UL flags apparent operational issues — inactive registration, refused service, address mismatch — for counsel’s attention on the dispatch day.

Undisputed Legal does not verify the legal sufficiency of the caption naming TransUnion LLC versus the NYSE parent or a TransUnion subsidiary. UL does not ensure that service complies with the specific procedural requirements of the plaintiff’s chosen forum or circuit. UL does not track statute-of-limitations deadlines, FCRA limitations periods, or matter-management timelines. UL does not classify the underlying claim under § 1681e(b), § 1681i, § 1681g, or a state FCRA analog. UL does not determine whether TransUnion LLC versus a TransUnion subsidiary is the correct defendant. UL does not advise on NY LLC Law § 304 substituted-service mechanics, Delaware § 18-105 direct-service strategy, or the selection between state-court and federal-court filing paths to address the New York registration gap.

Counsel determines the entity. Counsel determines the path. Undisputed Legal serves at the registered agent confirmed in current Delaware and state-of-qualification filings — never at TransUnion’s NYSE parent designation, never at consumer-facing dispute PO Boxes for litigation process, never at the Chicago headquarters reception desk.

FCRA matters carry elevated unauthorized-practice-of-law risk because caption decisions and procedural-path strategy interact directly with Article III standing requirements under Spokeo v. Robins, 578 U.S. 330 (2016), and TransUnion LLC v. Ramirez, 594 U.S. 413 (2021), and with the New York registration-gap problem that determines whether LLCL § 304 or FRCP 4(h)(1)(B) federal venue is the operative service path. Strategic judgment on those matters cannot be delegated to a process-service vendor. Undisputed Legal provides the operational delivery infrastructure; counsel provides the legal strategy.

How Undisputed Legal Approaches TransUnion Service

Undisputed Legal’s operational approach to TransUnion LLC service reflects direct-dispatch experience with the Corporation Service Company network across every active foreign-LLC state. Pre-dispatch registration verification, GPS-documented service events, and multi-state coordination protocols address the specific failure modes — inactive-registration dispatches, Chester-PA routing errors, and caption mismatches — that produce rejected returns in FCRA matters against TransUnion LLC.

Pre-Dispatch Entity Verification

Undisputed Legal verifies the Accurint and state-of-qualification filing record for TransUnion LLC before every dispatch. The protocol confirms three items in sequence: (1) the entity name in the caption matches a current active state LLC filing in the forum state — “TransUnion LLC” must appear verbatim in the state-of-qualification record, not as “Trans Union Corporation,” “TransUnion Corp,” or any abbreviated variant without the LLC designation; (2) Corporation Service Company is confirmed as the active registered agent as of the dispatch date via the CSC public records portal, not inferred from the state-filing date or a prior engagement’s address; and (3) the CSC address on the state filing matches CSC’s current internal records to catch any migration since the last state-filing amendment. Where step (1) returns INACTIVE or NOT IN GOOD STANDING for the forum state, the dispatch is escalated to the ordering attorney with a specific identification of the failure and a recommended procedural alternative — Delaware § 18-105 direct service, LLCL § 304 for New York state court matters, or FRCP 4(h)(1)(B) federal venue — rather than force-dispatched to the state-filing address.

GPS-Verified Affidavits and Documentation Standards

Every service event on TransUnion LLC is documented with a GPS-verified affidavit that includes device-coordinate timestamps at the moment of delivery, photo documentation of the CSC professional-desk acceptance interaction, and a record of the agent’s acknowledged receipt — name, role, time, and jurisdiction. The affidavit format meets the proof-of-service requirements for federal-court FCRA matters, where the return of service is entered into the CM/ECF docket and subject to challenge by TransUnion LLC’s litigation counsel. CSC’s professional-acceptance protocol produces a cleaner service record than officer-level service at 555 W. Adams Street, Chicago — the CSC agent’s name and role are documented by position rather than by individual officer identification, which eliminates the “wrong officer” challenge that arises from direct executive service at the headquarters address.

Attorney Engagement — Direct Lines for Multi-Jurisdiction Coordination

For FCRA matters filed in the Southern District of New York or Eastern District of New York, or for matters requiring NY LLC Law § 304 substituted-service through the Albany Department of State, Undisputed Legal’s NYC office handles dispatch coordination and LLCL § 304 process execution directly. For FCRA matters venued in the Northern District of Illinois or Cook County Circuit Court — TransUnion LLC’s home district and the Illinois state-court venue closest to its 555 W. Adams Street headquarters — Undisputed Legal’s Chicago office handles service at (312) 267-1227. Illinois-venued matters use CSC at 801 Adlai Stevenson Drive, Springfield, for state-court service, or 555 W. Adams Street with officer/managing-agent confirmation for FRCP 4(h)(1)(B) federal service. NYC and Chicago offices coordinate simultaneously for multi-venue FCRA class actions requiring concurrent dispatch to New York federal venues and Illinois state or federal venues.

Multi-State FCRA Class Action Coordination

For nationwide FCRA class actions naming TransUnion LLC as defendant — including post-Ramirez matters structured around the concrete-harm requirement that may require per-plaintiff dissemination evidence across multiple forum states — Undisputed Legal coordinates simultaneous dispatches across every active TransUnion LLC state through the Corporation Service Company network. Single-vendor registered-agent infrastructure makes 30-plus-state coordination operationally feasible without per-state vendor variance: the same CSC acceptance protocol applies in every active state, with only the physical address and the LLC-service statutory authority changing by forum. Pre-dispatch registration verification in each forum state precedes every dispatch in that state. Where a forum state’s TransUnion LLC registration is inactive — New York, Texas, and several additional states per current Accurint verification — UL identifies the correct procedural alternative at the pre-dispatch stage rather than dispatching to an agent address that will produce a rejected return.

Common Pitfalls in Serving TransUnion LLC

PITFALL 1: Naming “TransUnion” or “TransUnion Corp” Instead of TransUnion LLC. The most common caption error in FCRA matters against TransUnion is omitting or misstating the LLC designation. “TransUnion” without the “LLC” suffix does not correspond to the credit reporting agency’s legal name as confirmed under FEIN 36-4262739 and Accurint LexID 0001-4878-7477. “TransUnion Corp” or “TransUnion Corporation” names a different entity type and does not correspond to TransUnion LLC’s Delaware-LLC registration. Accurint Comprehensive Business Reports identify the entity as “TRANSUNION LLC” — the complaint caption must match this name exactly. A summons naming “TransUnion Corporation” served on CSC at 251 Little Falls Drive, Wilmington is served on an agent whose authority covers TransUnion LLC, not “TransUnion Corporation,” and TransUnion LLC’s litigation counsel moves on Rule 12(b)(5) insufficient service at the threshold — before any merits argument is briefed.

PITFALL 2: Service at 555 W. Adams Street, Chicago for Illinois State-Court Matters. 555 W. Adams Street is TransUnion LLC’s principal executive office — the address appearing in CFPB correspondence, Accurint records, and consumer-facing communications. It is not the registered-agent address for state-court service in Illinois. Illinois 805 ILCS 180/1-50 requires service on the designated registered agent. Illinois Corporation Service Company at 801 Adlai Stevenson Drive, Springfield, Illinois 62703-4261 is TransUnion LLC’s designated Illinois registered agent. A process server dispatched to 555 W. Adams Street for ILCS 180/1-50 service delivers to headquarters reception, which is not authorized to accept state-court process — the resulting return is challenged as insufficient service, and the service clock restarts. Federal FRCP 4(h)(1)(B) service at 555 W. Adams Street is permitted but requires delivery to an officer, managing agent, or general agent, not to a lobby reception desk.

PITFALL 3: Subpoena Routing Confusion — Chester PA vs. CSC. The Consumer Dispute Center at P.O. Box 2000, Chester, Pennsylvania 19016 is the correct routing address for records-only FRCP 45 subpoenas commanding production of a consumer’s TransUnion credit file by account number, Social Security number, or date of birth. It is not the correct address for litigation process or litigation subpoenas commanding corporate-representative depositions or document productions beyond the consumer’s own file. A deposition subpoena or summons and complaint delivered to P.O. Box 2000 Chester reaches the records-custodian team and does not reach TransUnion LLC’s legal department — generating a failure-to-appear or failure-to-respond result. CSC at the forum state’s registered-agent address is the correct service point for all litigation process and litigation-related subpoenas.

PITFALL 4: Stale CSC Addresses. Corporation Service Company has a documented pattern of updating internal registered-agent address records without simultaneously amending the corresponding state foreign-LLC filing for TransUnion LLC. A process server who pulls the registered-agent address from the state secretary-of-state filing without cross-referencing the CSC public records portal may dispatch to a building or suite that CSC has vacated for that state’s TransUnion LLC registration. The resulting rejected return restarts the service clock with potential statute-of-limitations exposure in matters filed close to the FCRA’s two-year discovery limitation. The pre-dispatch portal lookup takes under two minutes and eliminates the stale-address risk before the document leaves the office. A divergence between the state-filing address and the CSC portal address is an escalation before dispatch — not a force-send to the state-filing address.

PITFALL 5: Attempting CPLR § 311 Service in New York Without Checking Foreign-LLC Status. This is the TransUnion LLC-specific failure mode that does not apply to Experian Information Solutions, Inc. or Equifax Information Services LLC, both of which maintain active New York registered-agent designations. Accurint May 2026 verification shows TransUnion LLC’s New York foreign-LLC filing as INACTIVE under the legacy “TRANS UNION CORPORATION” name. A process server dispatched to a New York CSC office on a CPLR § 311 assignment — or dispatched to any New York address on the assumption that an active New York registered agent for TransUnion LLC exists — returns rejected because there is no New York-appointed agent authorized to accept CPLR § 311 service on TransUnion LLC’s behalf. The correct New York state-court service path is NY LLC Law § 304 substituted service through the New York Department of State, One Commerce Plaza, 99 Washington Avenue, Albany, New York 12231-0001. Any dispatch for New York state-court service on TransUnion LLC without pre-dispatch confirmation of active New York foreign-LLC status produces a defective return.

PITFALL 6: Naming TransUnion (NYSE: TRU) as Co-Defendant. The NYSE-traded parent TransUnion is not the credit reporting agency. Adding the NYSE parent as a co-defendant in a FCRA action does not add a reachable defendant — it adds a Rule 12(b)(6) motion for failure to state a FCRA claim against an entity that did not maintain the consumer’s credit file, did not process the reinvestigation dispute, and did not furnish the inaccurate information to any creditor or employer. Unlike the Experian Holdings situation — where a 2017 CFPB consent order provides an administrative captioning reference — there is no equivalent federal enforcement action naming the TransUnion NYSE parent as a FCRA respondent. TransUnion LLC alone is the correct FCRA defendant. An LLC-only caption proceeds directly to the FCRA merits; adding the NYSE parent creates threshold briefing that delays the substantive claims without adding a reachable defendant.

Why Undisputed Legal for TransUnion LLC Service

Multi-State CSC Network Direct-Dispatch

Undisputed Legal maintains direct-dispatch relationships with Corporation Service Company offices in every state where TransUnion LLC holds an active foreign-LLC qualification as of May 2026 Accurint verification. For single-forum FCRA matters, UL dispatches to the CSC registered-agent office in the forum state after completing the three-step pre-dispatch verification protocol. For nationwide FCRA class actions — including post-Ramirez matters requiring simultaneous service documentation across multiple forum states — UL functions as a single coordination point: one matter coordinator, one pre-dispatch verification chain per forum state, one unified return-of-service documentation package formatted for CM/ECF docketing. Where a forum state’s TransUnion LLC registration is inactive, UL identifies the correct alternative at the pre-dispatch stage rather than dispatching to an address that will produce a rejected return.

Pre-Dispatch Verification Protocol

Undisputed Legal applies a three-step pre-dispatch verification protocol before every TransUnion LLC service event. Step one: “TransUnion LLC” verbatim in the caption, verified against the current state-of-qualification filing — a caption naming “TransUnion Corp” or any variant without the LLC designation is escalated to the ordering attorney before dispatch. Step two: CSC’s active-agent status for TransUnion LLC in the forum state confirmed via the CSC public records portal — not inferred from the state-filing date or a prior engagement’s address. Step three: the CSC address on the state filing cross-referenced against CSC’s current internal records to catch any migration since the last state-filing amendment. A dispatch that passes all three steps proceeds with a confirmed agent address and a matching caption. A dispatch that fails any step is escalated with a specific identification of the failure and a recommended procedural alternative.

GPS-Verified Affidavits, CM/ECF-Ready Documentation, and Pricing

Every service event on TransUnion LLC is documented with a GPS-verified affidavit including device-coordinate timestamps, photo documentation of the CSC professional-desk acceptance interaction, and a complete agent receipt record. The affidavit package is formatted for direct CM/ECF docket entry, satisfying FRCP 4(l) proof-of-service requirements without supplemental affidavit preparation by the ordering attorney’s office.

Frequently Asked Questions — Serving TransUnion LLC

Who is the correct defendant — “TransUnion” or TransUnion LLC?

TransUnion LLC is the correct defendant for FCRA matters arising from consumer credit-file maintenance, accuracy, reinvestigation, and disclosure under 15 U.S.C. § 1681. TransUnion LLC carries FEIN 36-4262739 and is a Delaware-organized limited liability company established in 1977. “TransUnion” without the LLC designation, and “TransUnion Corp” or “TransUnion Corporation,” do not correspond to the FCRA-operating credit bureau as confirmed in Accurint Comprehensive Business Reports. The controlling Supreme Court standing decision for FCRA federal litigation identifies the defendant as TransUnion LLC — TransUnion LLC v. Ramirez, 594 U.S. 413 (2021).

How do I serve TransUnion LLC in New York?

TransUnion LLC has no active New York foreign-LLC registration as of May 2026 Accurint verification. CPLR § 311 service is unavailable because there is no New York-appointed registered agent. Two procedural paths exist. First: NY LLC Law § 304 substituted service on the New York Department of State at One Commerce Plaza, 99 Washington Avenue, Albany, New York 12231-0001 — the Department forwards process to TransUnion LLC’s Chicago address; service is complete upon Department of State acceptance. Second: file directly in SDNY or EDNY under 28 U.S.C. § 1331 and serve under FRCP 4(h)(1)(B) on Corporation Service Company at 251 Little Falls Drive, Wilmington, Delaware 19808, or at any active foreign-LLC qualification state. Undisputed Legal handles both paths.

What is the FCRA statute of limitations and how does service timing affect it?

15 U.S.C. § 1681p sets the FCRA limitations period at the earlier of two years from the consumer’s discovery of the violation or five years from the date of the violation. A rejected service return — for example, from attempting CPLR § 311 service in New York without confirming TransUnion LLC’s foreign-LLC status, or from dispatching to a stale CSC address in an active state — restarts the service clock. In matters filed close to the two-year discovery deadline, a stale-address or inactive-registration dispatch on TransUnion LLC can implicate the limitations period before a corrective service attempt is completed. Pre-dispatch registration verification eliminates the failure modes that most frequently cause service-clock resets in TransUnion LLC FCRA matters.

Why does TransUnion LLC v. Ramirez matter for my standing analysis?

TransUnion LLC v. Ramirez, 594 U.S. 413 (2021), established that only plaintiffs concretely harmed by a defendant’s statutory violation have Article III standing to sue in federal court. For FCRA matters, the concrete harm requirement means the inaccurate information in the TransUnion LLC credit file must have been disseminated to a third party — a creditor, employer, or landlord — resulting in an identifiable adverse decision, monetary loss, or reputational injury. An inaccuracy in a TransUnion LLC credit file that was never disclosed to any third party during the limitations period does not support a federal FCRA claim with Article III standing, even if the inaccuracy is clear and TransUnion LLC failed to correct it on reinvestigation under § 1681i. Counsel must evaluate the dissemination record before filing the federal complaint.

What is the difference between subpoena service for records and litigation service?

Records-only FRCP 45 subpoenas commanding production of a consumer’s TransUnion credit file route to the Consumer Dispute Center: P.O. Box 2000, Chester, Pennsylvania 19016 (physical facility at 2 Baldwin Place, Chester, Pennsylvania 19022). Litigation subpoenas commanding a corporate-representative deposition or document production beyond the consumer’s own credit file route to Corporation Service Company at the registered-agent address in the forum state — the same address used for service of the summons and complaint. A records-only subpoena delivered to CSC adds internal routing delay; a litigation subpoena delivered to P.O. Box 2000 Chester reaches the records-custodian team rather than the litigation service desk, generating a failure-to-appear.

Should I name TransUnion (NYSE: TRU) as a co-defendant?

No. The NYSE-traded parent did not maintain the consumer’s credit file, process the reinvestigation dispute, or furnish the inaccurate information to any creditor or employer. Adding the NYSE parent introduces Rule 12(b)(6) without adding a reachable defendant. There is no federal enforcement action naming the TransUnion NYSE parent as a FCRA respondent — unlike the Experian Holdings situation where the 2017 CFPB consent order provides at least an administrative captioning reference. TransUnion LLC alone is the correct FCRA defendant. A TransUnion-LLC-only caption proceeds directly to the merits; adding the NYSE parent generates threshold briefing that delays the substantive FCRA claims.

What if my matter involves TransUnion Healthcare or another subsidiary?

Matters arising from TransUnion’s healthcare revenue-cycle management operations name TransUnion Healthcare, Inc. as the correct defendant rather than TransUnion LLC. Matters arising from tenant screening name TransUnion Rental Screening Solutions, Inc. Matters arising from risk analytics and alternative-data products name TransUnion Risk and Alternative Data Solutions, Inc. The caption-controls-service doctrine applies across the TransUnion family: the entity whose systems and operations gave rise to the conduct alleged is the correct defendant, regardless of which “TransUnion” brand name appeared in the consumer-facing communication. Pre-filing matter classification is a pleading decision within counsel’s scope and must precede any service decision within Undisputed Legal’s operational scope.

Does Undisputed Legal coordinate nationwide FCRA class action service?

Yes. Undisputed Legal coordinates simultaneous dispatches across all active TransUnion LLC states through the Corporation Service Company network. Where forum states have inactive TransUnion LLC registrations — New York, Texas, and additional states per current Accurint verification — UL identifies the correct procedural alternative at the pre-dispatch stage and provides Delaware § 18-105 direct-service or LLCL § 304 substituted-service coordination as required. For post-Ramirez class actions requiring per-plaintiff dissemination documentation across multiple states, UL provides unified dispatch coordination, GPS-verified affidavits, and CM/ECF-ready return-of-service handling across all forum states under one matter coordinator.

Order TransUnion LLC Service Through Undisputed Legal

Undisputed Legal is the gatekeeper of litigation between counsel and the TransUnion LLC corporate defendant. Pre-dispatch registration verification, GPS-verified affidavits, and CSC-network direct-dispatch infrastructure produce CM/ECF-ready returns of service for FCRA matters venued in any federal district or active-qualification state — and LLCL § 304 process coordination for New York state-court matters where the CPLR § 311 path is unavailable. TransUnion LLC is served at the registered agent confirmed in current Delaware and state-of-qualification filings. The NYSE parent is not the defendant. The Chester PA dispute center is not the litigation service address. The Chicago headquarters reception desk is not an authorized service recipient for state-court process.
