(2) Inquiring about the number of credit cards in offline outlets: The personal credit report contains the number of citizens' credit cards, and cardholders can inquire about their own credit cards by inquiring about personal credit information.

As long as the cardholder takes his ID card to the local China People's Bank outlet, he can print his credit report, and then check his credit card number through the credit report.

If the cardholder has too many credit cards, the bank will think that the cardholder's potential debt is too high and may not be able to bear new debts. In order to reduce the risk of borrowing, banks usually reject the applications of borrowers with too many credit cards, and will not issue new loans or credit cards to these borrowers.
