It will change. At present, ICBC only has a gold card with a card change and no number change. Generally, ICBC debit cards can only change the bank card number if they report the loss. However, all bank cards have corresponding bank accounts. Although the card number has changed, if the account is not cancelled, how many times the card is changed will not affect the account number corresponding to the bank card.

The old bank card has been cancelled and can't be used after the credit card is reported lost, so don't worry about account security.
