The time is about 1 month, and the registered letter needs to be signed. After the new card is sent, a short message will be sent to your mobile phone registered in the bank with the number of registered letter on it. You can check it at your local post office. If it is not received within one month, call the customer service hotline of CCB at 400-820-0588.
There is also the question of repayment. You can repay with the previous card number, or you can call customer service to ask for the card number of the new card.
What I want to tell you is that if you can't get it, I suggest you try a more reliable address. Don't reissue your card. Call customer service, tell them that your card has never been received, and ask them to "mail" it for you, and no longer charge the loss report fee.
