If you spot an account you don’t recognize, check the same details across all three credit reports before deciding what happened. It could be a reporting mistake, a file mixed with someone else’s information, or identity theft. Dispute the specific error with the credit reporting company that lists it and the company that supplied the information; if identity theft seems likely, report it at IdentityTheft.gov and consider a free credit freeze.
Get all three credit reports
Request your reports from Equifax, Experian, and TransUnion through AnnualCreditReport.com, the official route identified by the Consumer Financial Protection Bureau (CFPB). The Federal Trade Commission (FTC) says free weekly online reports are permanently available. Separately, federal law entitles consumers to a free report from each nationwide credit reporting company every 12 months. The CFPB also describes an additional offer of up to six free Equifax reports during any 12-month period through December 2026; check the CFPB page for current terms if using that offer after that date.

Review each report separately. An account may appear on one report but not another, and an error at one reporting company does not automatically mean the others show the same information.

Compare the report with your bank and card statements, loan paperwork, and other account records. Look at the creditor’s name, account type, whether you are listed as an individual or joint owner or as an authorized user, open or closed status, opening date, balance, credit limit, and payment history. Check whether the account is listed more than once.
Also check the personal information attached to the report: names, addresses, and phone numbers. A report can contain someone else’s account because similar identifying details caused a “mixed file.” Other possible errors include incorrect ownership or status, inaccurate dates, balances, limits, and duplicate debts. An account you do not recognize is a reason to investigate, but it does not by itself establish who opened it or why. CFPB: Common credit report errors
Dispute the specific inaccurate entry
If the account is not yours or a detail is wrong, follow the dispute instructions on the report from the company that lists it. Identify the account and state exactly what is inaccurate and why. Include copies—not originals—of documents that support your explanation, such as relevant statements or records. Keep a copy of the report, your dispute, attachments, and delivery or submission confirmation.
Send a dispute to the furnisher as well—the lender, card issuer, or other company that supplied the information. CFPB guidance says furnishers generally must investigate and respond within 30 days. If information is wrong or cannot be verified, they must update or remove it and notify the reporting companies. That general period is not a guarantee that every case will be resolved within 30 days. CFPB: How to dispute a credit report error
Make the dispute detailed enough for the company to identify the exact item and understand the problem. A reporting company may decline to investigate a dispute it reasonably considers frivolous or irrelevant—for example, if it does not have enough information to locate the account.

If you believe someone opened the account using your information, report it at IdentityTheft.gov. The FTC provides a reporting process and recovery plan. Avoid responding to a suspicious collector using contact details from an unexpected message or call; use verified details on your report or the company’s official channel. FTC: Is a credit freeze or fraud alert right for you?
You can also choose a credit freeze, a fraud alert, or both. They work differently:
| Option | What it does | Trade-off |
|---|---|---|
| Security freeze | Restricts prospective creditors’ access to your credit file in most new-credit contexts. It is free and must be placed separately with Equifax, Experian, and TransUnion. | You may need to lift it temporarily when applying for new credit. CFPB says a freeze does not affect your credit score. |
| Initial fraud alert | Asks businesses to take steps to verify your identity before granting new credit. You can request it from one bureau, which must notify the other two. | It is less restrictive than a freeze. The FTC says it lasts one year and can be renewed for free. |
| Paid credit lock | A bureau service that may be bundled with other paid services. | CFPB says locks are no more effective than free security freezes and may cost money. |
If you are an identity-theft victim, the FTC says you may request an extended fraud alert, which lasts seven years. Details on freezes and locks are available from the CFPB; fraud-alert options are explained by the FTC.

Review the investigation result and escalate if needed
Read the investigation results and check the affected report again. The FTC says the bureau must provide its results in writing and a free report if the dispute results in a change. If the entry remains and you still believe it is wrong, you can contact the reporting company again and ask to add a brief statement explaining your dispute to your file. You may also submit a complaint to the CFPB. FTC: Disputing Errors on Your Credit Reports · CFPB: How to dispute a credit report error
