After receiving the credit card, the applicant cannot use it immediately and needs to be activated before it can be used. In order to avoid risks caused by mailing and ensure the safety of cardholders, Hebei Bank implements a credit card activation and use mechanism, that is, after receiving the credit card, cardholders need to activate it first and then use it. Cardholders can call the Hebei Bank customer service hotline, log in to online banking, and go to business outlets to activate their credit cards.
