Currently, you can check our bank’s credit card number through the following channels for your reference: 1. If your all-in-one card and credit card have signed a self-service agreement for transfer, please log in to mobile banking and click "Home" below - click " "Transfer" - "Transfer Management" - "Personal Account Transfer". If the card and the credit card have signed a personal transfer agreement, you can see the credit card number; 2. Please recall whether you have bound the credit card through third-party channels. You can try to check through the binding platform; 3. I try to check through the local counter; 4. If your family has helped you repay the money, you can confirm whether there is a record of the transfer out of the online bank or whether it can be checked.
