The United States Postal Service (USPS) is an independent branch of the federal government responsible for providing Postal Service in the United States. The USPS handles the mailing of letters and packages, sorting and delivering mail, and selling postal products like stamps, mailing supplies and commemorative items. This smaller sized post office offers the same services as larger ones on the mainland although there is no actual mail delivery on the island – all island residents get a free PO Box and they must stop in and pick up their mail from their P.O. Box. There is also an important community update board in the lobby.
