Summer Atlantic Post Office

The Summer Atlantic Post Office occupies a central position in downtown Stamford, just steps from the transit hub that connects the city to New York and New Haven by rail. Its location at 550 Summer Street makes it the most accessible USPS passport acceptance facility for residents of downtown Stamford, Cove, and the South End neighborhoods, as well as commuters traveling in from elsewhere in Fairfield County.

This facility accepts new passport applications and replacement requests for lost or stolen documents on an appointment basis. Agents process the DS-11 form, validate original citizenship documents and photo ID, and send applications directly to a federal processing center. The proximity to Stamford's business district means many applicants can combine a lunchtime passport appointment with their regular commute.

The Connecticut Passport Agency — the federal walk-in agency for urgent travel needs — is located nearby at 850 Canal Street in the same city. For a full picture of your options in town and across the state, see our Stamford passport office guide and the broader Connecticut passport offices directory.

Summer Atlantic Post Office is the most centrally located USPS passport acceptance point in Stamford. Because appointments fill quickly — especially in peak spring travel season — schedule your slot at tools.usps.com/rcas at least six to eight weeks ahead of your trip. Come prepared with your DS-11 form (do not sign it in advance), original proof of citizenship, a valid photo ID, and two identical 2x2 passport photos. Adult renewals via DS-82 go by mail and do not require a visit here. If your travel is within two weeks, bypass the acceptance queue entirely and go directly to the Connecticut Passport Agency in Stamford for an emergency appointment.
