Generally, registered letters of credit cards will have bar code numbers after mailing. Credit card applicants can find the barcode number of their registered letter by calling the customer service of the issuing bank or inquiring the website, and then log in to the China Post mail inquiry system from the Internet and enter the barcode number to inquire about the delivery of the registered letter of credit card.

It usually takes several days for a registered letter to arrive. It also depends on the distance between the issuing bank's credit card center and the applicant's city level. Generally speaking, the mail delivery speed of trunk mail (such as mail to and from big cities) is relatively fast.

The arrival time of registered credit card letters is about three to ten days. Credit card applicants can check the real-time arrival place of registered credit card letters through the post office after sending them, and each registered credit card letter has a traceable number.

There are usually two situations when a registered letter is not received by a credit card. One is that the address of the credit card registered letter is wrong, so the letter will be returned to the card issuing center; The other is that the registered letter of the credit card is taken away, which is more dangerous and easy to be stolen by criminals. Therefore, for the sake of safety, if the registered letter of the credit card is not received, the applicant must contact the card issuing center as soon as possible to explain the situation and let the credit card center handle the replacement.
