A credit bureau is an information clearinghouse that compiles information on consumers. The credit grantors, or lenders, report consumer payment history to the credit bureaus. The credit bureaus then compile that information together with information on tax liens, bankruptcies, and court judgments that is available in public records. In return, when consumers apply for credit, lenders can check credit reports to determine the creditworthiness of consumers.
