📖 About this office
USPS Twinbrook Station sits at 2001 Viers Mill Road in the Twinbrook neighborhood, a working-class residential community in eastern Rockville that has seen steady growth alongside the Red Line's Twinbrook Metro stop just blocks away. For residents of this corridor — stretching from Veirs Mill Road up toward the Rockville Pike — this post office is a more practical alternative to driving across town to the main post office on North Washington Street.
Passport acceptance here runs Monday through Friday from 10:00 a.m. to 3:00 p.m., and on Saturdays from 10:00 a.m. to 1:00 p.m., all by appointment. The Saturday window is a genuine advantage for applicants who can't break away from work on weekdays. Slots are limited, so booking several days out through tools.usps.com is strongly advised, particularly during the pre-summer rush from March through June.
Twinbrook Station feeds into the same State Department pipeline as any other USPS acceptance office, so processing timelines are identical regardless of where in Rockville you submit. For a comparison of all acceptance locations nearby, the Rockville passport offices page lays out hours and contact details side by side, and the broader Maryland guide covers the full state.
💡 Good to know
The Saturday morning window at Twinbrook Station is one of the few weekend passport acceptance slots in Rockville — useful if your weekdays are booked solid. Reserve your appointment at tools.usps.com/rcas/ and bring all required documents: completed DS-11 (unsigned), original proof of U.S. citizenship, government-issued photo ID with photocopy, and a 2x2 passport photo. The $35 USPS acceptance fee is separate from the State Department fee. Applicants who need same-day or rush processing should contact the Washington DC Passport Agency directly, about 20 miles south on I-270.
