There are three types of credit card passwords, namely phone banking password, online login password and transaction password. The phone banking password is different from the consumer cash withdrawal password. It is a six-digit password used by cardholders to enter the China Construction Bank telephone voice system or credit card channel to verify their identity. It is used when handling self-service inquiries on the official website or at the customer service hotline. Generally speaking, when opening a card, the self-service voice system or China Construction Bank customer service staff will prompt the cardholder to set it up on the phone. If the password has not been set yet, customers can call the customer service hotline 95533 to set it.
