Area code 347 is an overlay for all five boroughs of New York City, including the Bronx, Brooklyn, Queens, Staten Island, and parts of Manhattan. It was introduced in 1999 to complement the 718 area code, which was nearing exhaustion due to growing demand. The introduction of 347, along with later overlays like 929 and 917, allowed for the continued expansion of mobile and business lines across the city. While 718 carries historical significance, 347 is widely used and accepted throughout the outer boroughs. It reflects the city’s ever-growing and dynamic population.
