Geographic Coverage
Area code 202 covers the entire geographic boundary of the District of Columbia. Unlike most area codes, it does not span multiple counties or states. The District is divided into four quadrants - Northwest, Northeast, Southwest, and Southeast - and all neighborhoods within those quadrants fall under 202. Surrounding suburbs in Maryland and Virginia use separate area codes such as 301, 240, 703, and 571.
Population and Business Context
Washington, D.C. has a resident population of approximately 700,000, but the metro area including Northern Virginia and suburban Maryland exceeds 6 million people. The local economy is dominated by federal government agencies, defense contractors, nonprofits, law firms, lobbying organizations, and international institutions. The District hosts numerous Fortune 500 company offices, embassies, and media outlets, making 202 one of the most recognized area codes in North America.
Area Code History
Area code 202 was assigned in 1947 when AT&T and the Bell System created the North American Numbering Plan. It was among the original 86 area codes introduced at that time and has always been dedicated exclusively to the District of Columbia. The code has never been split or had an overlay code assigned, which is unusual given the growth many other original codes experienced in subsequent decades.
How to Dial
Callers within Washington, D.C. must use 10-digit dialing, meaning you dial the full 202 area code followed by the seven-digit local number. This requirement applies to all calls made within the District. No overlay code exists for 202, so there is no need to distinguish between competing codes when dialing locally. Long-distance calls to 202 from outside the District require dialing 1 followed by the full 10-digit number.
