Calling to report the loss and asking the bank to reissue the card is generally not a big deal, because the current credit card requires you to bring your ID card to the outlet to activate the credit card, but it is best to find out who signed it, and you can check the express delivery through the order number and so on.
But if you report the loss before receiving it, there is a problem, that is, they may cancel your credit card directly instead of sending it to you ~ ~
