Credit glossary
Credit file
The full record a credit bureau keeps about you, from which it produces the credit reports that lenders and you see.
Each bureau builds its own file from what furnishers send: identifying details, accounts, inquiries, and collections or public records. A file exists only once something has been reported. The CFPB's 2025 correction estimates that 2.7% of adults had no file at all in December 2020, while 9.8% had files too thin or stale to score.
Mistakes can attach someone else's information to your file. A mixed file happens when a bureau merges another person's accounts with yours because your identifiers look alike, and the FCRA requires bureaus to follow reasonable procedures to assure maximum possible accuracy. Read the personal information section of each report first, since a stray name or address tied to unfamiliar accounts is often the first clue.

- Mixed credit files: when someone else's accounts land on your reportA mixed file happens when a bureau merges your data with another person's. How it happens, how it differs from identity theft, and how to separate them.
