Dispute a Mixed or Merged Credit File (Letter Template)

Template, not legal advice. Fill in the bracketed fields, dispute only what you believe is inaccurate, confirm the current rule and statute of limitations for your state, and keep a dated copy.

A mixed file happens when a bureau blends your credit data with someone else’s — often a relative with a similar name, a Jr./Sr., or a person with a close SSN. Suddenly there are accounts, addresses, or inquiries that aren’t yours. This is an accuracy problem the bureau must fix under the FCRA.

What to gather

Your exact identifying info (full legal name, current address, DOB, full SSN on the letter to the bureau).
A clear list of which items are not yours.
Proof of your identity/address (copy of ID and a utility bill) to help them separate the files.

The letter

[Your full name]
[Your current address]
[City, State ZIP]
[Date of birth]   [Full SSN - bureau dispute]

[Date]

[Equifax / Experian / TransUnion - address]

Re: Mixed / merged credit file - request to separate and delete
[Confirmation number, if any]

To whom it may concern:

My credit report appears to be mixed with information belonging to another person.
The following items are NOT mine and must be removed from my file:

  1. [account/inquiry/address - as shown]  - not mine
  2. [item] - not mine
  3. [item] - not mine

I believe my file has been confused with another individual (possibly someone
with a similar name or Social Security number). To help you correct this, I have
enclosed proof of my identity and address.

Under the FCRA, please reinvestigate, separate my file from any other consumer's,
delete the items listed above, and send me a corrected report. Going forward,
please ensure my file reflects only my own information.

Enclosed: copy of government ID, proof of current address.

Sincerely,
[Your signature]
[Your printed name]

How to send it

Send certified mail with the identity documents to each bureau showing the mix-up. Mixed files can be stubborn; if disputes don’t resolve it, escalate with a CFPB complaint (consumerfinance.gov/complaint) and consider a consumer-law attorney — mixed-file cases are a recognized FCRA harm.

Notes. Be careful to dispute only the items that aren’t yours. Keep copies of everything; if the other person’s data keeps reappearing, document each occurrence — repeated reinsertion strengthens a complaint or claim. General information, not legal advice.
