If it is a China Merchants Bank credit card, when the validity period of the credit card is approaching, our bank will take the initiative to send a new card to the cardholder who is using the card normally, without any formalities. If the old card type has stopped being issued, other card types will be issued after expiration and will be mailed by registered mail. Generally, the delivery time of registered mail is within 15 days. After receiving the new card, please follow the card opening process to open and use the card. There is no fee involved in replacing the card. If the card type remains the same, the card number will not change.
