Area code 914

Area code 914 is the telephone area code in the North American Numbering Plan for Westchester County, New York.

The blue region is New York state; the red region is area code 914.

Area code 914 was one the first area codes announced when the North American Numbering Plan was created in October 1947.[1] It was originally assigned to Delaware, Dutchess, Nassau, Orange, Putnam, Rockland, Suffolk, Sullivan, Ulster, and Westchester counties, an area largely coextensive with the New York state portion of the New York metropolitan area, excluding New York City itself which received area code 212. In 1951, Nassau and Suffolk counties were separated from the rest, receiving their own area code 516,[1][2].

This configuration remained for 49 years. By the end of the 1990s, the increasing demand for cell phones and Internet dial-up connections caused concerns for exhaustion of the numbering pool. In mitigation, numbering plan area 914 was reduced to Westchester County on June 5, 2000. The remainder of the area was assigned the new area code 845. Area code 914 was retained by all cellphones in use in the plan area before the split.[2]
