e-OSCAR: How Credit Bureaus Process Your Dispute

Definition

e-OSCAR is the online system Equifax, Experian, TransUnion and Innovis use to send credit report disputes to the companies that reported the information, and to receive their answers. Your dispute is usually boiled down to a reason code and a short note before it is sent.

Also called: eOSCAR, Online Solution for Complete and Accurate Reporting, e-OSCAR dispute system

What it means

e-OSCAR stands for Online Solution for Complete and Accurate Reporting. It is the network that carries most credit report disputes between the bureaus and the banks, lenders, and collectors that report to them. You never log into it, but if you dispute an account, your dispute almost certainly passes through it.

Where it comes from

According to the CFPB’s 2012 report, the system started in 1993 under the bureaus’ trade group. It is owned by Equifax, Experian, Innovis, and TransUnion, and the current internet-based version dates to 2001. In 2011, about 16,000 furnishers were connected to it.

The CFPB describes the process this way. When you dispute, the dispute is given one or two reason codes from a standard list of 29, picked by you online or by a bureau representative for mail and phone disputes. It may resolve some disputes on its own. Otherwise, it sends the dispute to the furnisher on an electronic form called an ACDV, with an optional text field of up to 255 characters. The furnisher checks its records and answers through e-OSCAR. It can verify the account as reported, change it, delete it, or delete it as fraud. e-OSCAR’s own site says furnishers also use it to request out-of-cycle updates, called AUDs.

Common problems

The CFPB report notes that e-OSCAR did not then allow consumer documents to be attached and forwarded to furnishers, and that the bureaus generally did not pass along documents sent by mail. Consumer advocates have argued that a code plus a short note often leaves out the key facts. The report also notes that many furnishers automatically update an account when they get a dispute, so a “modified” result doesn’t always mean the furnisher agreed with you.

How to use this when you dispute

Write a dispute that can survive being shortened. Put the single most important fact in your first sentence, such as “This account is not mine” or “I paid this in full on [date].” Identify the account by name and number. Attach your proof anyway, because the FCRA requires the bureau to consider it. Then send the same packet directly to the furnisher, which has its own duty to look at what you send. Our dispute letter builder follows this approach.

When it can be an FCRA violation

The FCRA, at 15 U.S.C. § 1681i(a)(2), requires the bureau to send the furnisher “all relevant information regarding the dispute.” The FTC’s 2011 staff report says a bureau does not meet that duty if it only describes the type of dispute without passing on the evidence. When a dispute is reduced to a code and the error is verified anyway, that can support claims against the bureau and the furnisher.

If your dispute came back “verified” and the error is still there, FCRA Attorneys offers a free case review, and you pay no fee unless we win.
