The Three Credit Bureaus

There are three major credit bureaus in the United States: Experian, Equifax, and TransUnion. Each maintains its own file on you, which is why checking all three is essential.

Overview

The three major credit bureaus (also called Credit Reporting Agencies or CRAs) are independent companies that collect and maintain credit information on consumers. They gather data from creditors, public records, and other sources to create credit reports.

Because they operate independently, your credit report (and score) may differ between bureaus. A creditor might report to one bureau but not another, or the information might be updated at different times.

Why Are My Reports Different?

It's common to see differences between your three credit reports. Here's why:

Different Creditors

Not all creditors report to all three bureaus. Smaller banks might only use one.

Timing Differences

Bureaus may receive updates on different days of the month.

Data Variations

Name spellings and addresses may be recorded differently, leading to unmatched records.

Disputing with Each Bureau

When you find an error, you need to dispute it with each bureau reporting that information. An error might appear on all three bureaus or just one.

Sable generates customized letters for each bureau automatically based on your imported data.
