Used to calculate credit scores and determine creditworthiness, credit reports are comprehensive documents that detail a person or business's credit history, including their current and former lines of credit, bankruptcy records, and more.

Consumer loans for agriculture were likely first used around 3500 BCE, but modern consumer credit took many more centuries to be established. England's credit reporting system, for instance, dates back to the early 1800s when a group of English tailors began swapping information about customers who failed to settle their debts.
In the 1700s US economy, consumer credit reporting wasn't necessary. A loan to a farmer for agricultural supplies, for instance, would inevitably help them purchase both personal and business items.
By law, it's possible to get a free credit report once each year from Equifax, Experian, and TransUnion, the three major credit bureaus. The US government recommends using AnnualCreditReport.com to request these reports, as it's the only website authorized by the federal government to provide the legally mandated free reports.
It would be decades before the system evolved into something more formulaic. For instance, New York City's Mercantile Agency—which was created to formalize information and rumors about borrowers, sorting the reports into enormous ledgers—wasn't started until 1841.
Although today's credit scoring system is much more objective than, say, the credit assessment system of the 1700s, some argue there's still room for improvement, with critics saying the current system is still discriminatory. For example, while mortgage payments have long been automatically reported to credit bureaus, rent payments (the primary housing expense for most lower-income Americans) historically haven't been reported unless a payment was missed.
In 2026, four US senators sent letters to two of the nation's major credit bureaus (TransUnion and Experian) after an investigation revealed that they were fixing fewer errors on consumers' credit reports.
When they created FICO, William Fair, an engineer, and his cofounder, Earl Isaac, reasoned that financial data could help a wide variety of companies improve business decisions. FICO created the first credit scoring system to help lenders be more objective.
This podcast episode details a 2017 credit bureau hack in which Equifax data about millions of Americans was compromised. It dives into the history of credit bureaus, specifically how they became legally allowed to access Americans' financial information without Americans actually volunteering it themselves.
In the 1800s, credit bureaus went into business to help lenders make decisions. But today's three major credit bureaus, Experian, Equifax, and TransUnion, didn't become the industry leaders they are today until the 20th century, around the same time FICO was founded.
While the three main credit bureaus and the credit scoring companies aren't government entities, they are subject to certain US government regulations, such as the Fair Credit Reporting Act.

The United States is home to more than 33 million businesses, the vast majority of which are small businesses, with millions being created (and others closing shop) every year. These businesses often rely on loans, provide the goods and services that keep the economy flowing, and sometimes even grow large enough to enter public markets or provide private investment opportunities.
