1. After the application, before the new card is activated, the account of the original card still exists, and it can still be repaid directly to the original credit card account. It is suggested that before the new card is made, if the debt of the original credit card reaches the repayment period, it should be paid off as soon as possible to avoid overdue.

2. After applying for card replacement, if a new card is formulated and issued, the old credit card will be completely invalid from the moment the card is activated, and the new card can be used. The new card number is the same as the original card number, and the service function is the same. Then the debt bill of the previous credit card will be transferred to the new card and repaid directly to the new card.

3. What should I pay attention to when changing a new card: within one month before the card expires, the issuing bank will send the new credit card to the previous billing address. If the billing address registered in the bank has changed, please contact the bank customer service as soon as possible to update the address. During this month, the customer service of the bank will keep calling to confirm. Generally speaking, the cardholder will receive a new credit card from the bank one or two weeks before the card expires. If they haven't received the new card, they should also contact the relevant personnel of the bank in time.
