Changes and History of Washington, DC Area Codes:

Area code 202 was officially put into service.

Area code 202 is used exclusively inside of the District of Columbia.

Area code 771 was put into service as an all services overlay of area code 202 on 11/09/2021. Effective October 9, 2021 ten digit dialing (area code + seven digit number) became necessary in the 202/771 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
