Area Code: What You Need To Know
Since the creation of the North American Numbering Plan (NANP) in 1947, most of the inner ring of the Washington metropolitan area has been a single local calling area, the Washington Metropolitan Exchange Area (WMEA). This was despite the fact that WMEA was divided between three Numbering Plan Areas (NPAs): the District's 202, 301 in southern Maryland, and 703 in northern Virginia. From the 1950s to the 1990s, it was possible to complete local calls on WMEA with just seven digits. WMEA band long-distance services can be reached by dialing area code 202, for which AT&T Long Lines has established cross-reference operator routing codes for all affected central offices. The scheme was enforced by a central office code protection system in which central offices in the three numbering plan areas did not duplicate central office prefixes for any of the three area codes in WMEA.
If a 1-202-574 number is in use in the District, the corresponding 1-703-574 number or 1-301-574 number may be assigned only to jurisdictions within a safe distance from Southwest Virginia or the metropolitan area. Eastern Shore of Maryland. Conversely, if a 1-703-552 number is used in Northern Virginia or 1-301-552 in the Maryland suburbs, the corresponding 1-202-552 number cannot be used in the District.
By the spring of 1990, C&P Telephone (later part of Bell Atlantic and now Verizon), the regional Bell operating company for the district, notified the North American Numbering Plan Administrator (NANPA) that it would be the last exchangeable central office code in the region. Awarded in the second half of the year. As the remaining unique prefixes could not be assigned without breaking the seven-digit switching in the region, the C&P Central Office canceled the code protection scheme to make additional prefixes available for use. This change was implemented during the permitted dialing period from 1 April 1990 to 1 October 1990, during which time all Home NPA (HNPA) local calls maintained seven-digit dialing; For all HNPA direct toll calls, the digits 1 and t are required; Foreign NPA (FNPA) local calls are dialed using only t-digit number; FNPA direct dialed calls require dialing the digits 1 and t. All operator assistance calls are dialed as 0 and t digits.
D of the Central Office Code of Protection was intended to allow numbers in the Washington area not assigned under the previous system. However, this did not provide enough relief to meet the demand on both sides of the Potomac River. By late 1990, the Chesapeake and Potomac Telephone Company of Maryland realized that 301 was on the verge of exhaustion due to the end of the central office code protection scheme. It filed to assign area code 410 to most of Maryland east of the Baltimore area, effective October 5, 1991.

With 202 exhausted by the end of 2022, the North American Numbering Plan Administrator announced in October 2020 that area code 771 would be added to the District of Columbia's numbering plan area. The District of Columbia's Civil Service Commission approved a plan to phase in the new area code over a 13-month period.
