<P> On February 1, 1984, in response to a request from New York Telephone, the New York Public Service Commission voted to create a new area code to serve Brooklyn, Queens, and Staten Island . Previously, all of New York City had been served by area code 212 for 37 years . Despite protests from some local officials and state lawmakers, the commission was persuaded by New York Telephone's reasoning that a new area code was needed to "prevent an impending exhaustion of telephone numbers ." The new area code 718 entered service on September 1, 1984 . The split was implemented in a way so that the city's then - three million numbers were split roughly in half . Permissive dialing of 212 continued across New York City until January 1, 1985 . </P> <P> On July 1, 1992, the borough of The Bronx and the Manhattan neighborhood of Marble Hill were split from 212 and added to numbering plan area 718 . A permissive dialing period for using either area code 212 or 718 in the effected area lasted until May 16, 1993 . </P> <P> On October 1, 1999, area code 347 was added as an overlay code to area code 718 . </P> <P> On December 16, 2009, the New York Public Service Commission approved an additional overlay code for the 718 / 347 numbering plan area . On January 22, 2010, NeuStar announced another overlay code (929) for the New York City 718 and 347 area codes of boroughs outside Manhattan . Area code 929 became effective on April 16, 2011 . </P>
