Mixed Credit Files: When Someone Else Is on Your Report

A mixed file happens when a bureau merges your credit data with someone else's — often a person with a similar name or Social Security number. Suddenly their accounts, collections, or late payments appear on your report.

Why it's serious

Mixed files can tank your score and get you denied for loans over debts that aren't yours. They're also among the clearest FCRA accuracy violations when the bureau fails to fix them after a proper dispute.

How to fix it

• Dispute each account that isn't yours, in writing, with all three bureaus
• Provide identity documents proving the accounts belong to someone else
• Escalate to the furnisher and, if needed, the CFPB
• Keep every response — repeated re-mixing strengthens an FCRA claim
