Find any 516- phone number in New York

The 516 area code is part of the North American Numbering Plan (NANP). NANP is used to manage the task of assigning telephone numbers to each operating company. NANP divides the United States, Canada, and United States territories and possessions into geographic regions known as Numbering Plan Areas (NPAs). Each NPA is given a unique area code and is further divided into smaller geographic areas known as local exchange areas (LEAs).

The 516 area code encompasses the Nassau and Suffolk counties in Long Island, New York. The code was introduced in October 1999 as a result of the split of the 516/718 area code. The 516.718 split was the first geographically based split in New York, following the state's introduction of Number Portability in September 1992. The development of new technologies such as wireless phones and internet-based communications has prompted NANP to create more area codes and NPAs to meet the growing needs of consumers.
