Generally speaking, banks send credit cards by registered mail. When sending a credit card, the bank will give them a mailing number, and you can check the mailing progress in official website Post.
After the credit card department of the bank receives the application materials, it usually takes 10 working days for the audit department to complete the audit of the credit card.
After the approval, the bank will make a credit card within 2 working days, and then send it by registered mail in the order of the bill.
