The method for inquiring the complete card number of a credit card is as follows:

1. Cardholders can check at the counter of the bank branch to which the credit card belongs.

2. The cardholder can call the customer service phone number of the bank to which the credit card belongs and ask the manual customer service for help.

3. Cardholders can use the mobile banking APP to make inquiries.
