Area code 771 operates as an overlay for Washington, D.C., sharing the same geographic region with area code 202. Area code 202 was one of the original North American area codes established in October 1947. Area code 771 was added to the numbering plan area in April 2021 in creation of an overlay complex to mitigate impending telephone number shortages. The installation of a second area code required a transition to ten-digit dialing for all calls within the District. The overlay implementation commenced with a permissive dialing period from April 10, 2021, to October 9, 2021, during which ten-digit dialing of 202-telephone numbers was optional. The first central office code assignments for 771 took place on November 8, 2021.
Area code 771 is a General Purpose Code which was placed in service on January 1, 1947.
