If you know your score, you can get a sense of how lenders, insurance agencies, and interested employers view your credit: Excellent Credit: Credit Score Above 800. If your credit score is above 800, you have an exceptionally long credit history that is unmarred by things such as late payments, collections accounts, liens, judgments, or bankruptcies.
