📖 About this office
Back Bay Annex Post Office occupies the ground floor of a building on Clarendon Street between Copley Square and the South End, two of Boston's most vibrant and densely populated neighborhoods. The location puts it within easy reach of residents along Commonwealth Avenue and Newbury Street, students from nearby colleges, and visitors staying in the Back Bay hotel corridor who discover mid-trip that their passports are nearing expiration.
As a designated passport acceptance facility, the Back Bay Annex processes DS-11 applications — the form required for first-time adult passports, child passports, and certain renewals. Staff verify identity documents, witness signatures, and seal completed packages for State Department submission. Passport photo services are offered on-site, and the office is open for acceptance appointments on both weekdays and Saturday mornings, giving it one of the more flexible weekend schedules among Boston post offices.
Applicants navigating the difference between this office and the city's dedicated passport agency will find a concise breakdown on the Boston passport office guide. The broader statewide picture, including processing timelines and agency eligibility rules, is covered on the Massachusetts passport page.
💡 Good to know
The Green Line's Copley Station is a block away on Boylston Street, and the Back Bay commuter rail station is a four-minute walk along Dartmouth Street — making this one of the easiest post offices in Boston to reach from the suburbs. Saturday availability is a significant draw: weekend slots tend to fill faster than weekday ones, so book as early as possible if you need a Saturday appointment.
Note that passport acceptance offices forward your documents to the State Department — they cannot accelerate or track applications on your behalf. If you're facing urgent travel within 14 days, the Boston Passport Agency at 10 Causeway Street handles same-week expedited service by appointment only; book that through travel.state.gov rather than through USPS. For a list of all Suffolk County acceptance sites, the Boston passport locations page is a useful reference.
