What if I forget my bank card number and account number?

1. Online banking inquiry (take Huawei GRA-CL 10, system version number 10.0 1.38 EMUI as an example). The premise of this way of inquiry is that online banking has been opened. Users log in to official website Bank, enter the account number and password and log in to online banking, and then they can see the bank card account number in their personal accounts.

2. Customer service telephone inquiry. Users call the bank, turn to manual customer service according to the prompt, and then enter the user's personal ID number to query the bank card number.

3. Check at the bank counter. Users bring their personal ID cards to bank outlets, and bank staff will help check the bank card numbers.
