Sometimes referred to as a credit reporting agency, a credit bureau collects data from a consumer’s credit report based on information supplied by creditors, financial institutions, public records and businesses. A credit bureau collects data about you and your credit usage, including a list of current as well as past credit accounts, your payment history and if payments were made on time, as well as any negative details (missed payments, bankruptcies, foreclosures, collections or repossessions). The three credit bureaus include Equifax, Experian and TransUnion.
