ZIP code 20033 serves a concentrated business district along M Street NW in Washington, DC's Dupont Circle neighborhood. The postal facility operates as a dedicated PO Box center supporting 51 boxes and approximately 99 businesses in the Northwest Washington area.
This location doesn't serve residential addresses directly. Street delivery for the surrounding area comes through neighboring ZIP codes, primarily 20036, which provides carrier service to the Dupont Circle and Connecticut Avenue corridor. The single street designation (M ST NW with 52 delivery records) reflects the facility's focused business service role rather than a residential community footprint.
The ZIP's placement in one of Washington's prominent commercial and diplomatic districts means many boxes serve professional offices, lobbying firms, and small businesses that need a dedicated mailing address separate from their physical location. The Connecticut Ave-K Street vicinity has long functioned as a hub for associations, non-profits, and government relations offices.
The single street listing (M ST NW) represents the postal facility's address rather than a diverse service area. This pattern is typical for dedicated PO Box centers in urban commercial districts where the ZIP exists to provide mail service infrastructure rather than define a residential delivery territory.
ZIP Code 20033 is designated for PO Box delivery only; business establishment and employment data are not available.
