Ask the credit bureau to correct the specific information that does not belong to you, explain why you dispute it, and attach supporting copies. Also contact the business that supplied the disputed account information. If another person’s accounts or identifying details appear in your report, describe the mismatches precisely instead of sending only a general request to improve your credit. The CFPB dispute guide explains the bureau and information-provider routes.
This guide covers preparing and checking a mixed-file dispute in the United States, as of October 2026. It does not determine who owns a particular account. The worksheet and sample wording below are editorial preparation aids, not an official dispute form or a prediction of the investigation result.
Which entries suggest that the report contains someone else’s information?
Start with the report itself. CFPB describes a mixed file as information from different consumers combined in a single file, including accounts belonging to someone with a similar name. Its common-errors checklist also identifies wrong names, addresses and phone numbers, incorrect account ownership, duplicated debts, and inaccurate account status or balances.
Read identifying details alongside account entries. An unfamiliar address plus an unfamiliar account gives you separate items to examine. Neither observation by itself establishes how the information entered the report. A misspelling may be an error; a former address may be correct. Record what you know and what still needs explanation.
Unfamiliar accounts can also involve identity theft, which CFPB lists separately from mixed files. If you suspect misuse of your identity, follow the identity-theft resource linked in the CFPB dispute guide rather than treating everything as a clerical mix-up. You do not need to invent an explanation for the bureau’s matching process to describe an account you do not recognize.
For your own notes, connect each concern to a location in the report. Write the bureau name, report date, page or section, displayed business name, and account identifier as shown. Keep uncertain observations labeled as uncertain. For example, “I do not recognize this address” communicates something different from “This address belongs to a person I know.” Use the latter only if it is true and relevant.
What should you put beside each disputed item before submitting it?
Build an item-by-item worksheet. The purpose is to make the request readable, not to collect every financial document you own. The FTC correction guide recommends explaining each mistake, requesting correction or removal, enclosing supporting copies and a marked report, and keeping records of what you send. Dispute with each bureau that shows the mistake.
| Report item | What you observe | What you want investigated | Supporting record to consider |
|---|---|---|---|
| Unfamiliar address | The report shows an address you do not recognize | Whether that address belongs in your file | Relevant address documentation requested by the bureau |
| Unrecognized account | You do not recognize the listed account | Whether the account is attributable to you | Marked report excerpt and relevant correspondence |
| Incorrect ownership | The listed relationship does not match your records | The reported ownership or responsibility | Records explaining your relationship to the account |
| Disputed entry after a response | The entry remains despite your earlier request | The unresolved item and explanation | Earlier submission, receipt and result letter |
Use this as a planning table, not a universal attachment requirement. Check the bureau’s current instructions for identity verification and accepted documents. Provide relevant records through its designated process; do not publish your report or identification in a public comment or social-media post.
Before attaching a document, write a sentence explaining what it supports. If you cannot connect it to an error, reconsider whether it belongs in the packet. A document confirming your current address, for example, should not be described as proving your entire address history. Keep the scope of each explanation as narrow as the evidence allows.
Avoid combining an unfamiliar account with unrelated complaints about a score. A useful worksheet preserves the original entry, your reason for disputing it, and the requested change. It also leaves room to record the response beside the request, so that you can later see whether the investigation addressed the same issue.
How can you turn those observations into a clear dispute?
Write a short explanation for each disputed item. CFPB recommends including your contact information, the report confirmation number if available, the disputed account information, reasons for the dispute, and supporting copies. Keep your originals. Use the agency’s linked template if you prefer an official starting point.
Here is illustrative wording to adapt only where true:
I am disputing the account shown under [business name] in [report section]. I do not recognize this account as mine. The attached report excerpt marks the entry, and the attached records support the explanation below. Please investigate whether this account belongs in my file and correct or remove information found to be inaccurate.
Then add your actual explanation. If you also dispute an address, describe it separately. Do not claim that a relative’s file was merged with yours simply because you share a surname. Do not label accurate information as an error merely because it is unfavorable. The objective is an accurate report.
The business that supplied the entry is often called the furnisher. Use the dispute address identified in the report or the business’s current designated instructions. Your bureau request and furnisher request should describe the same underlying mismatch, while identifying the recipient correctly. Avoid sending a packet to an ordinary payment address without checking that it accepts credit-reporting disputes.
Save a copy of the actual submission, including attachments. FTC recommends certified mail with a return receipt for mailed disputes; bureaus also accept online and phone disputes. For an online submission, an editorial recordkeeping suggestion is to save the confirmation and the text you entered. Note any upload problem so your records distinguish what you intended to send from what you actually submitted.
What should you track while the investigation is pending?
Keep a simple log with the recipient, submission date, delivery or acknowledgment information, reference number, and documents sent. If you send relevant additional material, add that event rather than replacing the original entry. This helps you explain the sequence later without reconstructing it from memory.
According to CFPB’s investigation-timing explanation, a bureau generally must investigate within 30 days of receiving the dispute. An investigation can take up to 45 days in specified circumstances, including a dispute after receiving a free annual report or relevant additional information submitted during the initial investigation period. CFPB says the bureau has five business days after completing the investigation to notify you of the results.
Do not treat those periods as a promised date for a lender to reassess an application or for a score to change. Track the dispute and its response separately from any application deadline. If an application is pending, ask the lender what it needs and record its answer; this guide cannot establish the lender’s decision or timetable.
Read requests for additional information carefully. If a response says the dispute is insufficient or irrelevant, compare that explanation with what you submitted. A useful follow-up identifies the missing item or unanswered question and includes relevant support. Keep the response and your follow-up together so the record explains what changed.
How do you check the result and handle an unresolved mismatch?
Compare the result with your worksheet, not just the response’s general wording. FTC says the bureau must provide written results and a free report if the dispute produces a change. Check the affected address, account, ownership and status against your original request. Record which items changed and which remain unresolved.
As an editorial checking method, mark each worksheet row “corrected,” “unchanged,” or “needs explanation,” and write the reason. Do not mark the entire case resolved if the account changed but a separately disputed address remains. If the business name on the updated report differs, preserve both versions and ask how the response relates to your disputed entry.
For an unresolved bureau dispute, CFPB’s explanation of further options describes requesting a brief dispute statement in your file and seeking legal assistance or help from a state attorney general. A statement records a disagreement; it does not establish that an entry has been removed.
Before a CFPB complaint about inaccurate or incomplete report information, read its current complaint notice. It requires a direct dispute with the reporting agency first and says not to submit while the dispute remains pending unless 45 days have elapsed. The submission includes an attestation about the prior dispute and the truth of your information.
Prepare an unresolved-item summary from your records: what appeared, what you disputed, when you sent it, what response arrived, and what remains wrong. Attach relevant evidence through the official process. Keep factual observations separate from assumptions about why the error happened. That distinction makes the request easier to assess without promising a particular outcome.
