Portsmouth Post Office

The Portsmouth Post Office on Daniel Street sits in the heart of the historic downtown, a short walk from Market Square and the waterfront. As a USPS passport acceptance facility, it handles applications that cannot be renewed by mail: first-time adult passports, applications for minors, and renewals that fall outside the mail-in rules. Staff check your citizenship evidence, witness your signed application, seal the packet, and send it on to the State Department for processing. It's a convenient anchor for Seacoast residents and one of the acceptance offices serving Portsmouth and the wider Rockingham County area.

Bring your completed DS-11 (unsigned until asked), proof of US citizenship plus a photocopy, a valid photo ID, and separate payment for the State Department fee and the USPS execution fee. Photos can usually be taken on site for an added charge. Because passport hours can differ from regular retail window hours, confirm your appointment time when you book.
