Area codes 718

Area codes 718, 347, and 929 are telephone area codes in the North American Numbering Plan for the boroughs of New York City of the Bronx, Brooklyn, Queens, and Staten Island, as well as the Marble Hill section of Manhattan. They are part of a larger overlay plan with area code 917, which comprises all of New York City.

For the first 37 years after the establishment of the North American Numbering Plan in 1947, all of New York City was a single numbering plan area , area code 212. In 1984, New York Telephone asked the New York Public Service Commission to split part of New York City into a new area code to "prevent an impending exhaustion of telephone numbers." On February 1, 1984, the commission voted to split serve Brooklyn, Queens, and Staten Island into a new area code, with Manhattan and the Bronx retaining 212. The announcement of the impending split triggered protests and threats of legal action from local officials and lawmakers representing the outer boroughs. Despite this, New York Telephone implemented the new 718 area code on September 1, 1984. The split was implemented in a way that split the city's three million telephone numbers roughly in half. Permissive dialing of 212 continued across New York City until January 1, 1985.
