Find any 631- phone number in New York
The 631 area code is a North American Numbering Plan area code that is used to designate the Suffolk County region of New York. This geographical area covers the eastern tip of Long Island, which includes cities such as Patchogue, Huntington, Islip, Riverhead and the Hamptons. This area code was created in 1999 as a result of an area code split of the 516 code which was then reserved for Nassau County. This area code split was done to accommodate the massive growth that was occurring in Suffolk County. Despite the area code split, many consumers still retain their 516 numbers.
The North American Numbering Plan is a unified system of more than 350 area codes that are used throughout the United States and its territories. This numbering plan is administered by the North American Numbering Plan Administrator (NANPA), which is responsible for allocating specific area codes to telephone service providers. This numbering system also allows for easy identification of geographical areas, allowing for calls to be routed to their proper destinations. NANPA also regularly reviews the need for new area codes to accommodate population growth and the demand for new phone numbers.
