Buy a Local Phone Number – Area Code 771 (Arlington, District of Columbia)

Numbering relief in the nation’s capital brought an all-service overlay when area code 771 was introduced in the early 2020s for Washington, D.C.’s long-standing 202 plan. The overlay required 10-digit dialing but left existing numbers intact. For Arlington, across the Potomac from downtown, the change underscores how tightly woven the regional communications grid is: federal agencies, consultancies, and nonprofits often operate offices on both sides of the river, and contact points routinely span District and Northern Virginia prefixes.

Economic life in Arlington and the District revolves around a shared corridor of federal employment, defense installations, and a growing tech-services base. The Pentagon and a dense ecosystem of prime contractors anchor defense, while National Landing’s tech investments, proximity to Reagan National Airport, and Metrorail connectivity support cloud, cybersecurity, and logistics. Cultural identity blends policy and international affairs with neighborhood-scale arts, diverse dining, and civic volunteerism, and daily commuter flows bind Arlington’s urban centers to Capitol Hill, Foggy Bottom, and downtown offices.
