History of Suffolk County area codes

1947–1951: 914

With the announcement of a new nationwide telephone numbering plan by the American Telephone and Telegraph Company (AT&T) in October 1947, Suffolk County, Nassau County, the lower Hudson Valley, and some areas adjacent were assigned area code 914. [1]

1951–1999: 516

During 1951, area code 516 was assigned to Suffolk and Nassau, which were separated thereby from area code 914. [1]

1999–2016: 631

On November 1, 1999, area code 631 was created solely for Suffolk County, to satisfy the increased need for telephone numbers mainly due to cellular services, while Nassau County retained area code 516. Permissive dialing for numbers in 516 across Long Island continued until the spring of 2000. [2]

2016–present: 631/934 overlay

On July 16, 2016, area code 934 was assigned to overlay 631, which was nearing depletion of central office codes. This was the first overlay in an area in the state of New York outside New York City, and required ten-digit dialing for both area codes, effective June 18, 2016. [3]

The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the telephone country code 1. Some North American countries, most notably Mexico, do not participate with the NANP.

A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks.
