1. Call the bank's customer service:

1. If you want to inquire the credit card number, you need to know at which bank the credit card was processed first;

2. Call the customer service number of the bank and enter the ID number according to the requirements of the telephone process, and you can find your own credit card number information.

2. Go to the counter:

It's not as convenient to inquire about the credit card number at the counter as it is by telephone, but you can learn more about what you need to know. For example, some customers have lost their credit cards, and when they go to the counter, they can clearly understand what specific things they need to do to reduce their losses.

the above two methods can not only query the card number of the credit card, but also query the related information of the credit card. If the credit card is accidentally lost, customers need to report the loss quickly or freeze the credit card. Every bank will have relevant customer service for consultation.
