A credit score is a number associated with a person’s credit files to indicate their creditworthiness. Lenders - such as banks and credit unions - credit card companies, and merchants use credit scores to evaluate the potential risk posed by lending money to consumers. 

The credit issuers may use credit scores to determine who qualifies for a loan, at what interest rate, and at what credit limit. Credit scores are also used to facilitate decisions about hiring or job retention, or renting an apartment.
