About 771 Area Code
Area code 771 serves Washington DC exclusively as an overlay to the historic 202 area code. Introduced on November 9, 2021 by the North American Numbering Plan Administrator, 771 covers the exact same geographic footprint as 202 and was created to address projected number exhaustion in late 2022. The overlay means existing 202 numbers remain unchanged while new assignments may receive either code. Both codes support local voice and SMS-capable numbers used by federal agencies, government contractors, law firms, advocacy groups, and businesses across all sectors of the capital.
Washington DC's economy centers on federal operations, professional services, and government contracting. The 771 area code launched during a period of rapid expansion in these sectors. Local businesses use 771 numbers for constituent outreach, contract coordination, policy advocacy, stakeholder meetings, and client communications. While 771 is newer and less recognizable than 202, it still signals DC proximity and federal connection, delivering higher answer rates than toll-free or out-of-state numbers when contacting government decision-makers and beltway insiders.
FoneSwift lists live 771 inventory and capabilities on this page. Search numbers to see Voice, SMS and MMS support for each available option. Because 771 is newer than 202, you may find better availability and selection for vanity patterns or specific number sequences. If 771 inventory is limited, the historic 202 code serves the same geography, or nearby Maryland codes (240, 301) and Virginia codes (571, 703) cover the broader DC metro area.
Businesses using 771 numbers should display them in both local and E.164 formats (e.g., (771) 555-1234 and +1 771 555 1234) and register A2P messaging campaigns if running business SMS. For porting existing numbers, see our porting guide. Ten-digit dialing has been mandatory since October 24, 2021, so all calls within DC require the area code even for local destinations. Organizations choosing 771 get the same DC presence as 202 with potentially better number selection.

Area code 771 uses Eastern Standard Time (EST, UTC-5) during winter months and Eastern Daylight Time (EDT, UTC-4) during daylight saving time. Daylight saving time runs from early March to early November.
The 771 area code provides the same DC credibility and federal proximity as 202 with potentially better number availability due to its recent introduction. Washington DC shares LATA 224 with portions of Maryland and Virginia, creating a large toll-free calling zone across the capital region.
Quick Facts about 771 Area Code
Interesting tidbits about this area code 771
DC's first overlay
Area code 771 is the first overlay ever assigned to Washington DC, introduced after 202 served the capital alone for 74 years since 1947.
Planned transition
The 771 rollout followed a 13-month phased implementation with a permissive dialing period from April to October 2021, giving residents and businesses time to adjust.
Same geography as 202
Area code 771 covers the exact same area as 202, meaning both codes serve only the District of Columbia with no extension into Maryland or Virginia suburbs.
First assignments
The first central office codes assigned in 771 were 777 (November 8, 2021) and 888 (November 9, 2021), marking the beginning of new DC number assignments.
Prevents exhaustion
The 771 overlay was created because projections showed the 202 area code would run out of available numbers in late 2022 without relief.

How Does Local 771 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 771 number in Washington, D.C. and District of Columbia, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (771): directs the call to the Washington, D.C. / District of Columbia region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 771 555 1234 |
| Local Format (National) | (771) 555-1234 |
