Area Code 718 is a telephone area code that serves the boroughs of Brooklyn, Queens, and parts of Staten Island in New York City. It was established in 1984 as a split from the original area code 212, which covered all of New York City. This area code is primarily used for residential and business phone numbers in these boroughs. Due to the high population density and demand for phone numbers, area code 718 has been supplemented by additional area codes, including area code 347 and area code 929, to accommodate the growing need for telecommunications.
