Under normal circumstances, after the credit card is changed, the new card completely inherits the functions of the original card.

So the original fee and credit limit of the old card are directly transferred to this new card. For example, the billing information and credit limit will not change, but the validity period and credit card security code will change.

It is not excluded that the credit limit will change after card replacement. For example, if one credit card expires and another needs to be replaced, the bank will re-evaluate the credit card according to the card usage and credit status, and grant the credit line. At this time, the credit line will change, which may decrease or increase.
