The reasons for the difference are as follows:

When the credit card expires and is replaced, the card number will remain unchanged. If it is a replacement card, the card number will be different.

It may also have something to do with the bank that issued the credit card. Some bank credit cards are replacement cards with different numbers. The new card has the same functions as the original card. Third-party binding requires re-binding. If you want to pay in installments, please contact us. Contact the bank for processing.
