Section 623 of the Fair Credit Reporting Act — codified at 15 U.S.C. § 1681s-2 — is the primary statute governing what creditors, lenders, servicers, and debt collectors must do when they report information to credit bureaus and when consumers dispute that information. Understanding its structure is essential for both compliance professionals and litigators.
The FCRA defines a "furnisher" broadly as any person who regularly and in the ordinary course of business furnishes information to one or more consumer reporting agencies. This encompasses a wide range of entities:
The breadth of this definition matters. Any entity that sends account data to Equifax, Experian, or TransUnion — whether monthly Metro 2 files, collection placements, or public record data — is a furnisher subject to § 623's obligations. The statute does not require that furnishing be the entity's primary business; it only requires that it occur "regularly and in the ordinary course of business."
Section 623 is organized into two distinct subsections, each addressing a different phase of the furnishing relationship:
Governs what furnishers must and must not do when they report information to CRAs. These are proactive, ongoing obligations that apply every time data is transmitted.
Governs what furnishers must do after receiving notice from a CRA that a consumer has disputed the accuracy of reported information. These are reactive, time-sensitive obligations.
This two-part structure is critical for litigation strategy. A consumer who has not yet disputed an error with a CRA may have claims under § 623(a) if the furnisher reported information it knew or had reason to know was inaccurate. A consumer who has disputed and received an inadequate investigation has claims under § 623(b). Many cases involve both.
Section 623(a) imposes several specific prohibitions and affirmative duties on furnishers at the time of reporting. These obligations apply continuously — not just when a dispute arises.
A furnisher may not report information to a CRA that it knows or has reasonable cause to believe is inaccurate. This is a strict prohibition — not a best-efforts standard. If a furnisher's own records show that the reported information is wrong, continued reporting is a violation regardless of whether the consumer has disputed it.
"Reasonable cause to believe" is an objective standard. Courts have held that a furnisher has reasonable cause when the inaccuracy is apparent from the furnisher's own records, when the furnisher has received credible information suggesting inaccuracy, or when the furnisher's internal processes are known to produce errors of a particular type.
If a furnisher determines that information it previously reported is incomplete or inaccurate, it must promptly notify the CRA and provide corrected information. This duty is self-executing — it does not require a consumer dispute to trigger it.
In practice, this means furnishers must have internal quality control processes capable of identifying reporting errors. A furnisher that discovers through an internal audit that it has been reporting incorrect payment history on thousands of accounts has an immediate obligation to correct those reports — not to wait for consumers to dispute them one by one.
If a consumer disputes the completeness or accuracy of information directly with the furnisher (a "direct dispute"), the furnisher must note the dispute in subsequent reports to CRAs. This ensures that anyone pulling the consumer's credit report during the dispute period is aware that the information is contested.
When a furnisher sells or transfers a delinquent debt to another party for collection, it must provide the Date of First Delinquency (DOFD) to the transferee at the time of transfer. This prevents re-aging — the illegal practice of resetting the 7-year reporting clock when a debt changes hands. Failure to provide the DOFD at transfer is itself a § 623(a) violation, and the resulting re-aging by the debt buyer creates additional liability.
If a consumer submits an identity theft report and requests that the furnisher block reporting of information resulting from the theft, the furnisher must cease reporting that information. The furnisher may not re-report the blocked information unless it has a reasonable basis to believe the identity theft report was fraudulent.
Section 623(b) is triggered when a furnisher receives notice from a CRA that a consumer has disputed the accuracy or completeness of reported information. This notice typically arrives via the Automated Consumer Dispute Verification (ACDV) system — the electronic channel through which CRAs transmit dispute information to furnishers.
Upon receiving this notice, the furnisher has specific, time-sensitive obligations:
Conduct a Reasonable Investigation
The furnisher must investigate the specific dispute raised by the consumer. The investigation must be reasonable — courts have consistently held that simply re-verifying the information in the furnisher's own system without examining underlying documentation does not satisfy this standard.
Review All Relevant Information
The furnisher must review all relevant information provided by the CRA with the dispute notice. This includes any documentation or explanation the consumer submitted with the dispute. Ignoring consumer-provided evidence is a common and significant violation.
Report Results to the CRA
After completing the investigation, the furnisher must report the results to the CRA that sent the notice. If the information is found to be inaccurate or incomplete, the furnisher must report corrected information to all CRAs to which it originally reported the disputed data.
Modify, Delete, or Block as Appropriate
If the investigation reveals that the disputed information is inaccurate, incomplete, or cannot be verified, the furnisher must modify, delete, or permanently block the reporting of that information.
Complete Investigation Within 30 Days
While § 623(b) does not specify a deadline for furnishers directly, the CRA's 30-day investigation window under § 1681i(a)(1) effectively constrains the furnisher's timeline. Furnishers typically have 20–25 days to respond to an ACDV before the CRA must close the dispute.
The "Reasonable Investigation" Standard
Courts have defined a reasonable investigation as one that a reasonably prudent person would undertake under the circumstances. The standard is not perfection — but it requires more than a cursory review of the furnisher's own database. In Gorman v. Wolpoff & Abramson, the Ninth Circuit held that a furnisher's investigation is unreasonable if it fails to consider evidence that was available and relevant to the dispute. The more obvious the error, the more thorough the investigation must be.
In the real world, most § 623(b) investigations are conducted through the e-OSCAR system using Automated Consumer Dispute Verification (ACDV) forms. When a consumer disputes an item with a CRA, the CRA encodes the dispute into a two- or three-digit dispute code and transmits it to the furnisher via ACDV.
The furnisher's dispute team — often a small group handling thousands of ACDVs per month — reviews the dispute code, checks the account in the furnisher's system, and responds with a verification code indicating whether the information is verified, modified, or deleted. The entire process, from receipt to response, often takes less than five minutes per dispute.
The Core Problem with ACDV-Only Investigations
Courts have repeatedly found that an investigation consisting solely of checking the furnisher's own database — without reviewing the original account documents, the consumer's dispute explanation, or any supporting evidence — does not constitute a reasonable investigation under § 623(b). The ACDV system was designed for efficiency, not thoroughness. When a consumer provides documentation showing an error, that documentation must be reviewed. A furnisher that verifies disputed information without ever looking at the consumer's evidence has not conducted a reasonable investigation.
This gap between the statutory standard and the operational reality of ACDV processing is one of the most fertile areas of FCRA litigation. Expert analysis of a furnisher's ACDV response records — including response times, dispute codes used, and whether any documentation was reviewed — can establish whether the investigation met the § 623(b) standard.
Based on litigation patterns and expert analysis of furnisher data, the following violations appear with regularity:
The furnisher responds to an ACDV with a "verified as reported" code without actually reviewing the underlying account documents or the consumer's dispute explanation. This is the single most common § 623(b) violation.
When a consumer submits documents with a dispute — a payment receipt, a court order, a fraud affidavit — and the furnisher verifies the disputed information without reviewing those documents, the investigation is per se unreasonable.
Continuing to report a balance or delinquency on a debt that was discharged in bankruptcy. The furnisher's obligation to update its records after receiving notice of discharge is both a § 623(a)(2) duty and, after dispute, a § 623(b) duty.
When a consumer disputes that an account belongs to someone else (a mixed file), the furnisher verifies the account as belonging to the disputing consumer without conducting any identity verification. This is particularly egregious because the furnisher's own records may not contain the information needed to resolve the dispute.
After a dispute reveals an error, the furnisher corrects the information at the CRA that sent the ACDV but fails to correct it at the other two bureaus. § 623(b)(1)(D) requires correction at all CRAs to which the inaccurate information was reported.
After a CRA deletes disputed information, the furnisher re-reports the same information in a subsequent monthly data file. Under § 1681i(a)(5)(B), re-reporting deleted information is prohibited unless the furnisher certifies that the information is complete and accurate.
A debt buyer reports a DOFD that differs from the original creditor's DOFD, effectively re-aging the account. This violates both § 623(a)(5) (the seller's duty to provide DOFD at transfer) and § 623(a)(1) (the buyer's duty not to report inaccurate information).
The damages available under § 623 depend on whether the violation was negligent or willful — a distinction that dramatically affects the value of a case.
The willfulness standard under Safeco Insurance Co. v. Burr (2007) encompasses not only knowing violations but also reckless disregard of the FCRA's requirements. A furnisher that adopts a policy of verifying all disputes without investigation — knowing that this policy does not comply with § 623(b) — acts with reckless disregard and is subject to willful violation damages.
In class action litigation, the combination of statutory damages ($100–$1,000 per class member) and punitive damages can produce enormous aggregate liability. The $23 million TransUnion settlement discussed elsewhere on this site illustrates the scale of exposure when a furnisher's or CRA's systematic practices violate § 623 across a large consumer population.
For furnishers seeking to minimize § 623 exposure, the following practices are essential:
Implement Written Dispute Policies
Develop and maintain written policies and procedures for handling consumer disputes that comply with the FTC's Furnisher Rule (16 C.F.R. Part 660) and the CFPB's Furnisher Rule (12 C.F.R. Part 1022, Subpart E).
Train Dispute Staff on Reasonable Investigation
Dispute handlers must understand that verifying information in the furnisher's own system is not sufficient when the consumer has provided contradicting evidence. Training must address how to escalate disputes that require document review.
Preserve DOFD Data Through Debt Sales
Establish contractual requirements that DOFD data is included in all debt sale and transfer agreements. Implement quality control checks to verify that DOFD is populated correctly in Metro 2 files after a transfer.
Audit Metro 2 Data for Accuracy
Conduct regular audits of Metro 2 data files to identify systematic errors — incorrect payment history codes, missing or wrong DOFDs, accounts reported after bankruptcy discharge, or accounts past the permissible reporting period.
Correct Errors Across All CRAs
When an error is identified — whether through a dispute or an internal audit — correct it at all three major CRAs simultaneously, not just at the bureau that sent the dispute notice.
Document the Investigation Process
Maintain records of what was reviewed, what evidence was considered, and what conclusion was reached for each dispute. This documentation is critical in litigation to demonstrate that the investigation was reasonable.
Expert Witness Perspective
In § 623(b) litigation, I am frequently retained to analyze the furnisher's ACDV response records, Metro 2 data files, and internal dispute handling procedures. The analysis typically focuses on three questions: (1) What information did the furnisher have available at the time of the investigation? (2) What did the furnisher actually review? (3) Was the conclusion reached consistent with the available evidence? When the answer to question 2 is "only its own database" and the consumer provided contradicting documentation, the case for an unreasonable investigation is strong.
