What do you mean the courier signed for it?

Express delivery has been signed, which means that the goods are not signed by myself, but by others. Specifically, when the recipient is inconvenient to sign or can't contact the recipient, the courier will put the courier at the courier station or the collection point. Then the staff at the courier station or the collection point will send the pick-up code to the recipient in the form of short messages, and the recipient will take the pick-up code away. This process is called signing. It should be noted that signing on behalf of the courier does not mean that the courier has been impersonated or taken away, but that the courier has safely arrived at the collection point designated by the recipient. Express delivery, also known as express delivery or express delivery, refers to a new mode of transportation in which logistics enterprises (including freight forwarders) deliver documents or packages entrusted by users from the sender to the recipient's door quickly and safely through their own independent networks or in the form of joint ventures.
