Specifically, if the credit card expires and cannot be used, you can apply to the bank for renewal. The credit card is expired and cannot be used. Usually, the bank will send a notice to the cardholder to renew the card about two months before the expiration. If the cardholder does not apply to terminate the card, the bank will agree to renew the card by default, and make a new card and mail it to the billing address one month before the card expires. After getting a new card, the old card can be used until its validity period, but if the new card is activated, it will be invalid immediately. The new card carries the accounting information of the old card. Except that the validity period and security code will change, the credit card number will remain the same as before.
