What Is a Credit Bureau?

A credit bureau, also known in the U.S. as a “credit reporting company” or “credit reporting agency,” is an organization that collects and researches individual credit information and sells it for a fee to creditors, so they can make decisions on granting loans.1

Key Takeaways

  • A credit bureau collects and researches individual credit information and sells it for a fee to creditors, so they can make a decision on granting loans.
  • The top three credit bureaus in the U.S. are Experian, Equifax, and TransUnion, although there are a number of others as well.
  • Credit bureaus assign a credit score to an individual based on the credit history that they assemble.
  • Credit scores are important predictors of whether or not you will qualify for credit and on what terms.
  • Credit bureaus do not decide whether or not you will get credit; they merely collect and synthesize information regarding your credit risk and give it to lending institutions.

How Credit Bureaus Work

Credit bureaus partner with all types of lending institutions and credit issuers to help them make loan decisions. Their primary purpose is to ensure that creditors have the information they need to make lending decisions. Typical clients for a credit bureau include banks, mortgage lenders, credit card issuers, and other personal financial lending companies.1

Credit bureaus are not responsible for deciding whether or not an individual should have credit extended to them; they merely collect and synthesize information about an individual’s credit score and give that information to lending institutions. Consumers can also be customers of credit bureaus, and they receive the same service—information about their own credit history.1

Credit Scores

Credit bureaus acquire their information from data providers, which can be creditors, debtors, debt collection agencies, vendors, or offices with public records (court records, for example, are publicly available). Most credit bureaus focus on credit accounts; however, some also access more-comprehensive information, including payment history on cell phone bills, utility bills, rent, and more. Credit bureaus then use a range of methodologies to calculate a person’s credit score based on this credit history.1

FICO scores, created by the Fair Isaac Corporation in 1989, are the most common credit scores in the U.S.2 There are at least 19 commonly used FICO scores, and each is calculated differently with an eye toward different types of clients, allowing credit issuers to choose the type of credit score that best fits their inquiry.3 Credit bureaus then add the credit score to the information they’ve accumulated and issue a comprehensive credit report, which provides credit issuers with information that helps them determine credit approval and appropriate interest rates for borrowers. An individual with a higher credit score will likely have a lower interest rate on a loan.4

Major Credit Bureaus

While there are a number of credit bureaus currently operating in the U.S., the three main ones are Equifax, Experian, and TransUnion.6 In addition to using FICO scores, these three bureaus have also combined to create their own credit score, the VantageScore.7 Both scores are calculated on a range from 300 to 850, although initially VantageScore used a 501 to 990 range and some industry-specific FICO scores are graded on a 250 to 900 scale. However, FICO and VantageScore weight the importance of individual categories differently and so are generally dissimilar in their scores. A good FICO score, for example, is considered to be one in the 670 to 719 range, while a good VantageScore is in the 661 to 780 range.8 9

Another major difference between the scores has to do with their sources. VantageScores create a single score that can go with a credit report from each of the bureaus, based on information from all three bureaus. FICO, on the other hand, only uses information from one bureau for its score. So, for example, you could actually have three different version of your FICO 8 score, one for each of the three credit bureaus.8

You are entitled to one free credit report every 12 months from each bureau, but you may have to pay to see your credit score.

Credit Bureau Regulation

While credit bureaus don’t actually make lending decisions, they are very powerful institutions in finance, and the information contained in their individual reports can have a substantial impact on an individual’s financial future. The Fair Credit Reporting Act (FCRA), passed in 1970, regulates credit bureaus and their use and interpretation of consumer data. It is primarily designed to protect consumers from negligent or deliberately fraudulent information in their credit score reports.10

In 2003 the Fair and Accurate Credit Transactions Act (FACTA) updated the Fair Credit Reporting Act to give consumers the right to get one free credit report every 12 months from credit bureaus. It also gave them the right to purchase a credit score, complete with information as to how that score was calculated.11
