What Is e-OSCAR? Dispute Codes, Responses, and How the System Works

e-OSCAR is the system Equifax, Experian, and TransUnion use to send your credit dispute to the company that reported the item. When you dispute an account, the bureau usually doesn’t investigate it itself. It turns your dispute into one or two short dispute codes and sends them through e-OSCAR to the creditor or collector, which checks its records and answers. That’s why a detailed dispute can come back “verified” in a few weeks.

This guide explains how e-OSCAR works, the dispute codes and responses it uses, what the law requires of the bureaus and furnishers, and how to write a dispute that holds up in that system.

What Is e-OSCAR?

e-OSCAR (Online Solution for Complete and Accurate Reporting) is a web-based system that lets credit bureaus and data furnishers exchange disputes and corrections electronically. According to e-OSCAR’s website, it was developed by Equifax, Experian, Innovis, and TransUnion. It’s operated by Online Data Exchange LLC (OLDE), which the industry’s trade group created in 2006 to run it.

The scale is large. In its 2012 study of the credit reporting system, the Consumer Financial Protection Bureau found that consumers contacted the bureaus about 8 million times in 2011 to dispute 32 to 38 million items. The bureaus resolved about 15% of account disputes on their own and sent the other 85% to furnishers through e-OSCAR, which connected about 16,000 furnishers (CFPB, Key Dimensions and Processes in the U.S. Credit Reporting System).

Consumers can’t log in to e-OSCAR or see the forms sent about them. It’s a back-office system for bureaus and furnishers.

How Does a Dispute Move Through e-OSCAR?

1. You dispute with a bureau. You send a letter, file online, or call Equifax, Experian, or TransUnion.
2. The bureau codes your dispute. An employee or automated process reads your dispute and picks one or two dispute reason codes. It may add a short free-text note and, since a 2013 system upgrade, can attach documents you sent.
3. e-OSCAR routes an ACDV to the furnisher. The Automated Credit Dispute Verification (ACDV) form carries your identifying information, the account as the bureau shows it, and the dispute codes.
4. The furnisher responds. It checks its records and answers that the account is accurate, changes it, or deletes it.
5. The bureau updates your file and notifies you. If the furnisher changed or deleted the account, e-OSCAR also sends a “carbon copy” of that change to the other bureaus the furnisher reports to.

That last step is why a correction at one bureau usually reaches the others, and why it sometimes doesn’t. Our guide to why one bureau deleted an account but the others didn’t explains the gaps.

The bureaus must generally finish the investigation within 30 days of receiving your dispute, or 45 in some cases (15 U.S.C. 1681i).

e-OSCAR Dispute Codes

Each ACDV carries one or two dispute reason codes that tell the furnisher what you’re disputing. These are the codes in e-OSCAR’s current dispute and response code job aid (revised February 2020). The list has changed over time: the National Consumer Law Center reported 26 codes in 2009, and the CFPB described 29 in 2012.

If you’ve seen older lists, a few codes were split into more specific ones. Disputed dates (old code 105) are now 114 and 115, special comments and compliance conditions (107) are now 116 and 117, and balances (109) are now 118. Codes 008 (late due to change of address) and 014 (paid before collection status) no longer appear.

Which codes are used most?

A few codes carry most disputes. In the last three months of 2011, 33% of e-OSCAR disputes claimed an account didn’t belong to the consumer, 15% claimed the information was inaccurate, about 4% disputed the current balance, and another 4% involved collections the consumer said they weren’t aware of (CFPB, 2012). An earlier breakdown cited by the National Consumer Law Center found that five codes accounted for about 84% of disputes.

The catch-all codes are the problem. “Consumer states inaccurate information” or “Claims company will change” tells the furnisher almost nothing. In one federal case, the court described a “claims company will change” notation as a “cursory notation” that gave “no suggestion of the nature” of the consumer’s dispute, and held that the furnisher’s limited investigation was reasonable as a result (Gorman v. Wolpoff & Abramson, 9th Cir. 2009).

e-OSCAR Response Codes: What Can a Furnisher Answer?

The furnisher answers each ACDV with a response code. These are the codes in e-OSCAR’s reference card for responding to ACDVs (May 2020):

Two of these deserve attention. Code 23 lets a furnisher confirm the disputed item and update something else, so the result can say “updated” while your problem stays. Code 24 is the answer to a vague dispute: the furnisher says your dispute wasn’t specific, confirms who you are, and updates the account as it sees fit.

The same reference card says that when a bureau attaches images of your documents, the furnisher must view, print, or download each one.

If the furnisher doesn’t respond in time, the bureau deletes the disputed information. Here’s how disputes routed to furnishers were resolved in 2011, from industry figures the CFPB published:

“Modified” covers a wide range. As response code 23 shows, a furnisher can update an unrelated field, such as the balance, while leaving the item you disputed unchanged. That’s why the result letter isn’t the end of the story: compare your updated report against what you disputed.

Why Do e-OSCAR Disputes Come Back Verified?

• Your letter is compressed into a code. A two-page explanation can become “Consumer states inaccurate information.”
• Volume is high. Bureau employees have testified to quotas requiring roughly one dispute every four to six minutes (NCLC, 2009). In one case, TransUnion clerks were expected to handle ten investigations an hour (Cushman v. Trans Union, 3d Cir. 1997).
• Furnishers check their own records. If the furnisher’s system shows what the bureau shows, the easy answer is “accurate as reported.”
• Documents don’t always get used. The CFPB found in 2012 that bureaus generally weren’t passing consumers’ documents to furnishers. After the 2013 upgrade, it found bureaus had built systems to forward them, but also that at least one bureau failed to review attached documentation and relied entirely on the furnisher (CFPB Supervisory Highlights, 2017).

What Does the Law Require?

The credit bureaus

Under the Fair Credit Reporting Act, a bureau must conduct a reasonable reinvestigation of a dispute. Courts have held that it can’t always just pass the dispute along and accept the answer:

• Stevenson v. TRW Inc. (5th Cir. 1993): TRW relied solely on the furnishers’ responses to its dispute forms. The court said “a credit bureau must bear some responsibility for evaluating the accuracy of information” and upheld a negligence finding (opinion).
• Cushman v. Trans Union Corp. (3d Cir. 1997): the bureau’s “grave responsibility” under the FCRA “must consist of something more than merely parroting information received from other sources.” In some circumstances, a bureau may have to verify its source (opinion).
• Richardson v. Fleet Bank of Massachusetts (D. Mass. 2001): a jury question existed where Equifax kept relying solely on the bank’s information after being alerted that the source might be unreliable (opinion).

The furnishers

A furnisher that receives a dispute from a bureau must also conduct a reasonable investigation, review the information the bureau sends, and correct the item at every nationwide bureau it reports to if it’s inaccurate (15 U.S.C. 1681s-2(b)).

• Johnson v. MBNA America Bank (4th Cir. 2004): an investigation means “a detailed inquiry or systematic examination,” not a superficial one. A jury could find that simply matching the ACDV against internal records, without checking underlying documents, wasn’t reasonable (opinion).
• Gorman v. Wolpoff & Abramson (9th Cir. 2009): reasonableness is judged by what the furnisher learned about the dispute from the bureau’s notice. A vague code supports a limited investigation.

The CFPB told furnishers in 2013 that they must review all relevant information, including documents the bureau sends with the dispute (CFPB Bulletin 2013-09). In 2015 settlements with state attorneys general, the three bureaus also agreed to forward consumers’ supporting documents to furnishers and to have trained employees review disputes involving fraud, identity theft, and mixed files.

How Do You Write a Dispute That Survives e-OSCAR?

You can’t control which code the bureau picks, but you can make the right one obvious:

• Name the field, not just the account. “The date of first delinquency is reported as 03/2024; the account was current until 08/2024” points to a date code. “This account is wrong” points to “Consumer states inaccurate information.”
• One problem per point. Separate the late payment from the balance from the status, so each can be coded and checked.
• Attach evidence and say what it shows. A payment confirmation means more when your letter says which month it proves.
• Use the other bureaus’ reporting. A month reported current at one bureau and late at another is a specific, checkable inconsistency.
• Dispute with the furnisher directly, too. A dispute sent straight to the creditor or collector doesn’t go through e-OSCAR or get compressed into a code. The furnisher has to investigate it under its own direct-dispute rules (Regulation V, 12 CFR 1022.43).

That last point is why SmartDispute’s first round goes to the furnisher and to each bureau showing the problem on the same day. The furnisher sees your full dispute, the bureau starts its own investigation, and you can compare the answers.

How Does e-OSCAR Relate to Metro 2?

Metro 2 is the data format furnishers use to report accounts to the bureaus. ACDVs use the same Metro 2 fields, so the account details on an ACDV, and any corrections the furnisher sends back, are expressed in Metro 2 terms. Our guide to Metro 2 and the “Metro 2 compliance” hype explains the format and why it isn’t a dispute strategy on its own.

Frequently Asked Questions

What is e-OSCAR?

e-OSCAR (Online Solution for Complete and Accurate Reporting) is the system credit bureaus and furnishers use to exchange disputes and corrections electronically. It was developed by Equifax, Experian, Innovis, and TransUnion and is operated by Online Data Exchange LLC.

Can consumers access e-OSCAR?

No. e-OSCAR is only for credit bureaus and the companies that report to them. You see the result through the bureau’s response and your updated credit report.

What is an ACDV?

An Automated Credit Dispute Verification is the electronic form a bureau sends through e-OSCAR to a furnisher. It carries your identifying information, the account as reported, and one or two dispute codes.

What’s the difference between an ACDV and an AUD?

A bureau sends an ACDV when a consumer disputes. A furnisher sends an Automated Universal Dataform (AUD) on its own to correct an account between its regular monthly reports.

Where can I find the e-OSCAR dispute codes list?

The table above lists the codes in e-OSCAR’s current job aid, revised in February 2020. Older lists you may find online include codes that have since been replaced, such as 105, 107, and 109.

Does e-OSCAR mean nobody reads my dispute?

Not necessarily, but your dispute reaches the furnisher in condensed form. Clear, specific disputes with documents give both the bureau and the furnisher less room for a quick “verified.”

What can I do if my dispute keeps coming back verified?

Compare the response with what you disputed, send a more specific follow-up with your evidence, and dispute directly with the furnisher. If the problem continues after several documented rounds, you can file a complaint with the CFPB.

What’s the Next Step?

Look at the items you’ve disputed and ask what code each dispute would turn into. If the answer is “inaccurate information,” rewrite it around the specific field, month, or amount that’s wrong, and send it to the furnisher and the bureaus together.
