Did you know...Credit bureaus matter because they shape your credit reports and scores, which influence whether you can get loans, credit cards or even housing. Since your information can vary by bureau, it’s important to check all three, dispute errors quickly, and use tools like credit freezes when needed.
What are the 3 credit bureaus?
The three major credit bureaus are Equifax, Experian and TransUnion. Credit bureaus gather and maintain data on consumers' credit use, which means that if you have a credit card or a loan, you probably have a credit file with one, two or all three major credit bureaus.Sometimes called credit reporting agencies, these credit bureaus can collect and sell information on your consumer credit behavior without your consent. However, businesses that check your credit, such as credit card issuers and lenders, must have a legitimate reason to look at your credit file — for example, a lender might look at your credit because you applied for a loan or a credit card. In most cases, potential lenders must have your permission.If data privacy is a concern, you should know that credit bureaus are highly regulated by the Fair Credit Reporting Act, which puts limitations on how they collect and share your personal data.»Get your free credit reportfrom NerdWallet today »Get your free credit reportfrom NerdWallet today

How is the information on your credit reports used?
The information in your credit reports goes far beyond borrowing — it can influence major financial and everyday decisions. Here are some of the most common ways it’s used:Calculating your credit scores.Determining whether you qualify for a loan or credit card, and what interest rate you’ll pay. Reviewing your background for certain job applications. Approving or denying a rental application. Setting the cost of some types of insurance. Deciding whether you’ll need to pay for a deposit for utilities.
What information is not in my credit reports?
Your credit reports do not contain your credit score. The major credit scoring companies, FICO and VantageScore, use the data from your credit reports to calculate your score. Some types of accounts don't routinely show up on your report, such as utilities and rent. But those accounts can still end up on your report if there's a payment problem that leads to a debt collection, which is a negative mark that appears on your credit reports. Other personal information is excluded, such as your race, marital status, religion, gender, citizenship or criminal records.
Where do the credit bureaus get their data?

Credit scores are numbers based on the information in your credit reports. The most common scoring models (like FICO and VantageScore) look at five main things: payment history, credit use, length of credit history, types of credit and how often you apply for or open new accounts.These formulas weight each factor differently, which is why your FICO score and VantageScore are different. Because each bureau may have slightly different information, your credit scores may vary.Are credit scores from all major bureaus the same? Are credit scores from all major bureaus the same? Actually, credit bureaus don't calculate your credit scores. They provide the information that FICO and VantageScore use to calculate your scores.There's a few reasons why you have multiple credit scores and they don't exactly match:Each of the three major credit bureaus (Equifax, Experian and TransUnion) may have slightly different information about you. Why? Lenders don’t always report to all three bureaus and, as a result, the data in each report can vary—and so can the scores based on those reports.You don't have a single credit score. Different scoring models (like FICO and VantageScore) can produce different numbers even using the same report.The bottom line: Your credit scores should be in a similar range, but it’s normal for them to differ a bit across bureaus and scoring models. The only cause for worry is if one bureau reports a score that is drastically different from the other two. Then, it’s time to check your credit reports for errors and dispute them.Explore more on About the authors Barroso Amanda Barroso, Ph.D., is a writer and content strategist helping consumers navigate budgeting, credit building and credit scoring.
