An account bank refers to a bank that opens a bank account. Generally speaking, when you apply for a passbook or bank card for the first time and put it in your bank, there will be registration in the passbook, which usually refers to "XX branch". There are several ways for CCB credit card bank inquiry:

1. SMS inquiry: send the SMS "khcx# bank card number" to 95533.

2. Telephone inquiry: dial 95533 by mobile phone or fixed line, and transfer to manual service according to voice prompts. Then ask the bank through the card number.

3. Inquire about outlets: With your ID card and CCB card, go directly to the nearby CCB business hall and inquire at the relevant staff.
