The Top 3 Credit Bureaus of the US and Their Key Functions

Did you know that there are three major credit bureaus in the U.S. that notice the way you spend money? They then report this information to several lenders and creditors, which can substantially impact your financial standing. Read on to learn more.

What is a Credit Bureau?

A credit bureau is an agency that collects and gathers information about your financial history. By tracking consumer information—including financial and medical records, payments, insurance claims, residential or tenant history, and employment history—they play a big role in helping creditors make lending decisions. There are three major credit-reporting agencies in the U.S.—Equifax, Experian, and TransUnion.


This Atlanta-based company is spread across 24 countries in North America, Latin America, and Europe. Founded by Guy Woolford in 1899, Equifax now has an annual revenue of $3.4 billion. The company offers identity theft protection, credit fraud protection, and manages credit reports.

Equifax is most notably known for its 2017 security breach, affecting 147 million consumers across America. Since then, the company released a tool to check for information breaches and offered free credit monitoring services to affected customers.


Experian is known as the world’s leading information service company that is based in Dublin and now operates with 16,600 employees in over 37 countries worldwide. It was founded as the Commercial Credit Nottingham (CCN) in 1980, and reached the U.S. a decade later as TRW Information Services.

In 2018, Forbes titled it one of the “World’s Most Innovative Companies”, as it used FICO 8 credit score calculation and also offered a Credit Tracker upon subscription. Storing credit information of 220 million U.S. consumers and 40 million businesses, Experian also had a system security breach in 2015 that exposed 15 million user accounts.


This Chicago based company provides risk scores, credit-decision capabilities, consumer reports, and analytical services to global companies. Consumers across the U.S. use its services to view their credit profiles, manage their financial data, and protect themselves against identity theft.

Unlike Equifax and Experian, TransUnion began as a private company. It went public in 2015 and began to trade under the stock symbol TRU. It has grown exponentially with over 4,700 employees and total revenue of $2.371 billion, serving a billion consumers worldwide.
