How many days does it take for letters from the same city to arrive? What if you don't get it?

Surface mail takes 2-3 days. If the recipient doesn't receive it, and the address and postal code are correct, he can only admit that he is unlucky, because surface mail can't be inquired (it is suggested to add 3 yuan registration fee, so that the whereabouts of the mail can be inquired through the mail office). The requirement that there is no time for the same city express is usually the next day. If the recipient doesn't receive it and the courier doesn't contact the recipient, he will leave a receipt notice on the recipient's door or mail it to the mailbox. The telephone number and delivery time of the delivery office were indicated again, and the delivery was made again the next morning. Normal delivery twice, the recipient can make an appointment with the delivery office to deliver again. And express mail can be queried through the internet. You can call 1 1 185 for the post office.
