Generally speaking, it takes about 10 days from mailing to delivery. During the delivery period, the landlord can check the delivery status through the registered letter code in the card-issuing message of CCB, and through the postal website (Baidu search "receiving and sending mail tracking query system", a system specially used by postal services to query registered letters). If you go to the local post office, it is suggested that someone sign for the card at the card receiving address (CCB now delivers it by registered mail). If multiple deliveries are not signed, they may be returned to Shanghai. Of course, you can also consider taking your ID card and this registered letter code to the post office to collect it yourself, so that you feel more reliable. After all, the card is linked to money, so it is more reassuring to do it yourself.
