On September 1, 1984, area code 718 was introduced as a split from area code 212, assigning 718 to Brooklyn, Queens, and Staten Island while 212 was retained for Manhattan and the Bronx. This was the first area code split in New York City, dividing the city's telephone subscribers roughly in half.

Permissive dialing allowed the use of either area code until January 1, 1985, when 718 became mandatory for the affected boroughs.
