It was one of the area codes originally assigned in October,1947 .As of
2006 , there are no plans to split or overlay the area code, as the North American Numbering Plan Administration estimates the current supply of 202 numbers sufficient at least to the year 2020. [ [http://www.nanpa.com/pdf/NRUF/2006-2NPA_Exhaust_Projections.pdf 2006 NRUF and NPA Exhaust Analysis] ] For a local call between two telephones in the District,7-digit dialing is permitted, although the call will be connected if the area code is dialed. There is, of course, no provision for long-distance calls within the area code. [ [http://www.nanpa.com/nas/public/npa_query_step2.do?method=displayNpa&npaReportModel.nasNpaId=202 NANPA Administration System: Area Code 202] ]Originally, area code 202 was an unpublished alternate area code for the nearby suburbs in
Maryland andVirginia , which were officially in area codes 301 and 703, respectively. That arrangement allowed local calls throughout the metropolitan area to be dialed using only seven digits. For example, a telephone number inKensington, Maryland , that was officially 301-949-xxxx could be dialed as 202-949-xxxx as well. However, onOctober 1 ,1990 , due to pending number exhaustion, the ability to dial the suburbs using area code 202 ended, and local calls between area codes required10-digit dialing (area code + number, leading "1" is not required but is usually not forbidden).ee also
