When a customer applies for a bank credit card, it usually takes 10 working days from the time the application materials are received by the audit department to the time the credit card is audited. After the approval, the bank will handle the card for the customer within 2 working days, and then send it by registered mail according to the billing address. Generally, the sending time of registered letters is 15 days. If you haven't received it for a long time, please call the banking service hotline for detailed verification.
