202 Area Code – Washington, District of Columbia: Location, Time Zone & History

Area code 202 is one of the original North American area codes assigned in 1947, and from the start it was set aside to cover the entire District of Columbia. Unlike many of its peers, 202 has never undergone a geographic split; the district's numbering plan grew instead through the addition of an overlay. That overlay, area code 771, was introduced in 2021, with permissive 10-digit dialing beginning that April and mandatory 10-digit dialing following that October, after which the first 771 numbers were put into service. Today the combined numbering plan area serves a population of about 690,000, according to the 2020 U.S. Census.

The territory includes Washington itself along with Georgetown, Capitol Hill, and Anacostia, neighborhoods with distinct identities that nonetheless share a single area code and, since 2021, a second one layered on top of it. The local economy reflects the city's role as the seat of the federal government, supplemented by:

• Federal government
• Tourism and hospitality
• Information technology
• Higher education and research
• News media

This area code also carries cultural weight beyond telecommunications. It helped give rise to the regional "DMV" identity, popularized by local hip-hop artists in the mid-2000s. The area is also home to go-go music, which emerged in Washington's Black neighborhoods in the 1970s and was named the official music of Washington, D.C. in 2020.
