1. The credit card center will send a new card, and the card number will remain unchanged. Generally, when a credit card expires and the credit card center will send a new card directly, there is no need to change the credit card number. The new card number will be the same as the old card. But there are two places that will change, one is the validity period of the card, and the other is the CVV2 code on the back, which is the security code.

2. If the new card is not received and the card is sent a second time, the card number will change. During the process of replacing the new card, if the cardholder fails to receive the new card as scheduled, he should call the credit card bank immediately. Contact the customer service center for inquiries. After confirming that the card has been lost, the bank will handle the lost card securely to prevent the card from being used fraudulently. Then, the bank will issue a new card for free and resend it to the cardholder. However, it should be noted that the card number will be changed when the new card is sent by the bank for the second time.

3. If you change your youth card when it expires, the card number will change. Many banks have launched youth cards with clear regulations on the age of application. For example, China Merchants Bank’s young card, Pudong Development Youth Card, etc. require you to be 30 years old. It can no longer be used. If you apply when you are 27 years old and change the card before the validity period, your age will naturally exceed. The bank will not issue you another youth card, but will issue other card types. In this case, the card number It will change.
