What must a recipient present for an Adult Signature delivery?

For an Adult Signature delivery, the recipient must present a valid form of government-issued ID. This requirement ensures that the package is being handed over to the intended adult recipient, as specified by the sender. The use of a government-issued ID, such as a driver's license or passport, serves as an official means of verifying the identity and age of the person receiving the package. This measure is important in preventing unauthorized individuals from collecting sensitive or valuable items, thereby maintaining security and compliance with postal regulations.

Other options such as proof of payment, a previous delivery notice, or a reference number are not sufficient for confirming identity in this context. While important for certain delivery processes, they do not serve the primary purpose of ensuring that the individual receiving the parcel is indeed the adult designated by the sender.
