Your Credit Report: The File You Didn't Write

Three private companies keep a file on your borrowing life, sell it to lenders, landlords, and insurers, and never asked your permission. You can read all three for free, every week.

Three companies, three files, one formula

Equifax, Experian and TransUnion each maintain a file on your borrowing life and sell it to lenders, landlords and insurers. Nobody asked your permission — the arrangement is governed by federal law rather than by consent.

The critical distinction is between the report and the score. The report is the raw data: accounts, payment history, inquiries, collections, public records. The score is just a formula run over that data. Change the report and the score follows; you cannot change the score directly.

You can read all three reports for free every week at AnnualCreditReport.com — the official site authorised by federal law. The weekly access that began during the pandemic was made permanent.

Why your three scores don't match

Lenders aren't required to report to all three bureaus, and many report to only one or two. So each bureau's file can genuinely contain different accounts, different balances, and different update timing.

Run the same formula over three different datasets and you get three different numbers. None of them is 'wrong' — they're answers to slightly different questions.

This is a practical reason to check all three rather than whichever one your bank shows you for free. An error sitting on one bureau's file is invisible from the other two.
