Take the credit card of China Merchants Bank as an example. When the validity period of the credit card is about to expire, our bank will take the initiative to issue a new card to the cardholders who normally use the card without going through any formalities. If the old card type has stopped issuing, another card type will be issued after the expiration, and it will be registered mail. Generally, the sending time of registered letters is within 15 days. Please follow the card opening process after receiving the new card. There is no charge for changing cards. If the card type remains the same, the card number will not change.
