When the credit card expires, the credit card center will issue a new card directly, and generally there is no need to change the credit card number.

In addition, when the cardholder's card is damaged, the magnetic stripe cannot be sensed, and it is difficult to continue to use it. When it is necessary to change the card, there is no need to change the number of the credit card.

However, in some cases, it is necessary to change the card number. For example, when the new card that should be sent is not received on time, the card number will change when the cardholder applies for a new card. Because this is equivalent to reapplying for a credit card and registering an account in the bank. For example, if the cardholder issues a new card after reporting the loss, the card number will also change.
