Key Takeaways

Experian, Equifax, and TransUnion are the major credit bureaus that lenders and borrowers use.
Creditors may access credit information from different credit bureaus to make lending decisions.
If you notice an error on your credit report, you should file a dispute with the credit bureau to remove the inaccuracy.

If you have a lot of experience managing credit cards, you may already be familiar with the credit bureaus (also known as credit reporting agencies). Creditors, such as your mortgage lender or credit card company, typically report data like your payment history and balances to the credit bureaus. The credit bureaus use that information to create your credit reports and credit scores.

Several credit bureaus typically receive your credit information and create separate credit reports. Different mortgage or auto lenders, banks, credit unions, credit card companies, and other financial institutions may rely on information from specific credit bureaus to make informed lending decisions. But that doesn’t necessarily mean one credit bureau comes out on top.

Which credit bureau is used the most?

There’s not one single credit bureau that most lenders or consumers use.

Three major credit bureaus — Equifax^®, Experian^®, and TransUnion^® — collect consumer credit information and provide credit reports, credit scores, and other services. It’s a good idea to check all three reports before applying for a new credit card.

See if You’re Pre-Approved

Data from each of the three major credit bureaus is used widely to make lending decisions, like loan or credit card approval, interest rates, and credit limits.

Which credit bureau is most accurate?

Fortunately, you generally don’t have to worry about the major credit bureaus providing inaccurate information on your credit report or to credit card issuers.

Under the Fair Credit Reporting Act, credit reporting agencies must ensure that your credit information is accurate and remove inaccurate information from your credit file, according to the Federal Trade Commission (FTC).

All three credit bureaus have to maintain high accuracy standards. You may notice different details across your credit reports, but the information should be accurate unless there’s a mistake on your report or you’ve experienced identity theft.

What if there’s a mistake on your credit report?

Mistakes on your credit report may impact your credit score until they’re resolved. If you notice inaccurate credit information, like a missed payment that you know you’ve paid, you may file a dispute online, by mail, or over the phone with the credit bureau that issued the report, the creditor, or both.

You typically have to provide some personal information, like your name and address, as well as account information. Then, describe the problem in detail. If possible, provide supporting documentation, like proof of payment.

The credit bureau has 30 days to investigate your dispute, according to the FTC. If they agree that the information is inaccurate, it will be removed from your credit history.

While inaccuracies in your personal information, like a typo in your name or Social Security number, may not have an immediate effect on your credit scores, you should also dispute those errors to avoid future credit issues.

Why are credit scores different from different credit bureaus?

The credit scores you receive from each credit bureau may differ for a couple of reasons.

Creditors don’t always report all your activity to all three credit bureaus. So, the credit bureaus may use different information to calculate your credit score. For example, your credit card company may report your credit usage to Equifax^®, but not TransUnion^® or Experian^®.

Each credit bureau may also use a slightly different credit scoring model to calculate your credit score. That means certain factors, like the length of your credit history, may impact some scores more than others.

Even though your credit scores may not be identical, they’re usually fairly close. Positive credit habits, like paying on time each month and keeping your balances low, often have a positive impact on all three credit scores.

The bottom line

Experian^®, Equifax^®, and TransUnion^® are widely used by borrowers, lenders, and businesses in the U.S. and beyond.
