Area codes 212, 646, and 332
Area codes 212, 646, and 332 are area codes in the North American Numbering Plan (NANP) for most of the borough of Manhattan in New York City. By area, it is one of the smallest numbering plan areas (NPAs) in the country. The area codes form an overlay complex, and are also overlaid by area code 917 of a numbering plan area that comprises the entirety of New York City.
Area code 212 is the original code assigned for all of the city in 1947. Its use was restricted to just Manhattan and the Bronx in 1985, when area code 718 was created for the city's other three boroughs; the Bronx received area code 718 in 1992. Subsequently, area code 646 was assigned as an overlay code for Manhattan in 1999, and area code 332 was added in 2017.
