31: You have no open bank credit card accounts.
The VantageScore credit score model relies on information in your credit files at the three national credit reporting companies (Equifax, Experian and TransUnion) to generate your score. Because you have no open bank credit card accounts, your credit file does not contain enough information about your use of credit. A mix of different types of open and active credit accounts, including bank credit card accounts, can have a positive impact on your credit score.
Maintaining open and active credit accounts in good standing can help improve your credit score.
