Mixed credit file: what it means

A mixed file is a credit report that combines two different people's information in a single file. It often happens when accounts belonging to someone with the same or a similar name show up on your report.

In Spanish it is

Expediente mezclado (mixed file)

Also written as: mixed file · mixed credit report

The full explanation

According to the CFPB, a credit reporting company that matches information to a person only because the names are identical or similar is not using reasonable procedures to keep its reports accurate. If your report shows accounts, debts or addresses that are not yours, you can dispute them in writing with the credit reporting company and with the company that supplied the information.

An example

Reviewing his report, Juan Carlos García finds a card in collections and an address in another state. They belong to a different Juan Carlos García. He sends a written dispute to the credit reporting company and to the company that reported the debt, with copies of documents that back him up.

You will see it in…

  • Your credit report, in your personal information and the list of accounts
  • The dispute letter you send to the credit reporting company
  • An adverse action notice, if you are denied credit because of information that is not yours
An older man and his daughter go over papers with a professional.
