You can add the names of up to 5 individuals/businesses authorized to receive mail at your mailbox. Each recipient will need to provide two valid forms of identification in order to complete the mandatory PS Form 1583. Each add-on pays a $5.00 set up fee. You can permit people to pick up your mail by lending them the key to your mailbox. Possession of the mailbox key shall be considered valid evidence that the possessor of the key is duly authorized to remove any contents from the mailbox. We cannot hand out mail to anyone not listed as the owner of the box.
