Your credit score is a numerical value representing the potential risk of lending to you, while your credit rating is a lender’s assessment of your history with them. Your credit rating is assigned both a letter (indicating the type of credit used) and a number (indicating how promptly you paid off the debt). The letters used are as follows:
O (Open line of credit)
R (Revolving credit)
The numbers next to the letters range from 1-9 with 1 indicating that you always pay on time and 9 indicating a bad debt or an account that has gone to collection.
