The 516 area code

North American area code 516 is a telephone area code in the state of New York. 516 serves the Nassau County portion of Long Island.


Upon nationwide adoption of area codes in October 1947, Nassau and Suffolk counties, and the lower Hudson Valley, were assigned the 914 area code. In 1951, Nassau and Suffolk were reassigned to the 516 area code.[1]

Despite Long Island's dramatic growth in the second half of the 20th century, this configuration remained in place for six decades. However, by the late 1990s, the proliferation of cell phones and pagers made it obvious that Long Island needed another area code. On November 1, 1999, 516 was reduced to Nassau County, while Suffolk County was reassigned the 631 area code. Permissive dialing of 516 across Long Island continued until the spring of 2000.[2]
