703 Area Code: Arlington, Virginia

The 703 area code covers Arlington, Fairfax County, and the broader northern Virginia suburbs of the Washington metropolitan area. Arlington anchors the directory's records here. The county sits across the Potomac from Washington, organized around the Pentagon, Arlington National Cemetery, and a substantial concentration of federal employment, defense contractors, and the corporate headquarters that have grown up around them. The 703 footprint extends through Fairfax, Alexandria, Reston, Tysons, McLean, and the surrounding cluster of Washington-area suburbs that have grown enormously through recent decades.

Records linked to 703 numbers in the directory often include Bristol, Lynchburg, Richmond, and Roanoke — Virginia cities outside the 703 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Virginia and addresses linked across multiple cities. The directory currently documents 684 distinct prefixes within 703 in detail, a working subset of the prefix population the code carries.

Arlington's median household income is the most striking demographic feature: at well above the US figure, the county carries one of the higher city-level income readings in the country. Home values come in close to three times the US median, the median age sits close to the US reading, and population places Arlington among the larger Virginia jurisdictions. The broader 703 footprint reflects an unusually high overall demographic profile relative to most of the country, with sharp variation between the inner Arlington and Alexandria neighborhoods and the more residential outer suburbs.
