202 Area Code: Washington, Washington, DC

Washington, DC, is served by the 202 area code, the only code covering the District of Columbia and one of the original area codes in the North American Numbering Plan. The District sits along the Potomac River between Maryland and Virginia, organized around the L'Enfant-designed grid of avenues and quadrants that radiates from the United States Capitol. The local working economy reflects an unusually concentrated mix of federal government, professional services, lobbying and policy work, healthcare, and higher education — Georgetown, George Washington, American University, and Howard among the larger campuses. The 202 footprint covers the District in its entirety.

Because 202 covers the District alone and is famously associated with federal Washington, the directory's records associated with 202 numbers do not surface a recurring set of secondary cities through the routine cross-linkage patterns that dominate larger codes. Where other-place names do appear, they reflect the same kinds of public-record dynamics seen elsewhere — numbers porting between carriers, addresses tied to multiple residences across the surrounding Maryland and Virginia suburbs, and prior registrations surfacing alongside current ones. The directory currently documents 599 distinct prefixes within 202 in detail, a working subset of the prefix population the code actually carries.

The District's median household income runs above the US figure, supported by the substantial federal and professional-services wage profile. Home values come in well above the national median — roughly two-and-a-half times the US figure — the median age sits a few years under the US reading, and population places Washington among the larger cities in the country.
