Dover Main Post Office

The Dover Main Post Office at 55 Loockerman Plaza is the official U.S. passport acceptance facility in the center of Delaware’s capital. It sits right on Loockerman Street — downtown Dover’s pedestrian-friendly commercial spine — a short walk from Legislative Hall, The Green and the Kent County government buildings, so it’s an easy stop to fold into other civic errands. The office handles first-time passport applications (Form DS-11) and passports for minors, and takes the regulation photo on-site. All passport service is by appointment, Monday to Friday, booked by phone at 302-734-5822 or through the USPS scheduler. If your travel date is tight or the Dover slots are full, there are acceptance offices right across Delaware, including nearby Smyrna just up US-13 to the north.

Parking is available in the lot at Loockerman Plaza plus metered spaces along the downtown streets, but give yourself a few extra minutes right now: a new Kent County library is under construction next door and the surrounding parking is temporarily disrupted. Coming without a car is easy too — the Dover Transit Center (468 West Water Street) is a short walk away, and DART First State routes 100 and 104 stop in the downtown core. One tip: if you only need to renew an eligible adult passport, you can usually mail in Form DS-82 and skip the in-person visit — this office is for first-time applicants and minors, who must appear. Heading to the coast for the summer? The Milford office to the south is another handy option on the way down.
