There are two ways to renew your credit card.

One is to apply for a new card at the nearest business outlet.

On the other hand, when the card is about to expire, a new card will be issued to you.

Generally speaking, changing a new card means that the credit card account number and credit limit remain unchanged, and only a new credit card is given (changing cards at outlets). If you re-mail, you will give a new account, but the information remains the same and the amount remains the same.
