Will the postman call me if my courier arrives? How do I know the mail has arrived?

Generally, it is delivered directly to the door, and when no one signs for it, they will hang up and contact the recipient. If there is a phone, the postman will call the recipient if he can't find it, and will deliver it to the door soon after knowing the detailed address. If you want the recipient to pick it up, you must bring your ID card, and I will go to the post office to pick it up myself. If the sender has handled the information communication business, he will send a text message to remind you when the email arrives!
