The official rule is to sign for it, which is stipulated by the courier company, but now many couriers don't have to sign for it to save time. In this case, contact the courier and ask the doorman to sign his name. The doorman can't sign your name, which means you have signed for it.

Express delivery does not have to be signed in person before it can be signed. When the courier calls the recipient to collect it, the recipient can entrust a designated person to sign for it.

Courier generally only authenticates the recipient's phone number, so as long as the phone number is right, you can pick up the piece, so as long as you are yourself, you can also discuss with the courier who to sign for or where to put it.
