If you still have friends familiar with the original factory, you'd better ask if the card has arrived for you. If you don't contact anyone, it's not convenient for you to check in the past. You can only call CCB's 400 credit card customer service hotline to manually update your contact address, and then CCB will look at it according to your card mailing situation. If the original card is sent to the factory and no one signs for it, it will be re-sent to the new address. If it shows that you have signed for it, you should void the previous card, make a new card and send it to your new address. China Construction Bank will also send you a notification message when issuing a credit card. There is a mailing number in the text message, so you can track the delivery progress online by yourself.
