The telecommunications landscape of the United States is a patchwork of area codes, each with its unique history, geography, and cultural significance.

This comprehensive guide dives into the origins, coverage, and modern-day significance of these two area codes, providing a detailed perspective on their roles in communication.

Area Codes in the US

In the North American Numbering Plan (NANP), the U.S. state of New York has telephone overlay area codes 516 and 363. Nassau County on Long Island is included in the numbering plan area (NPA). Area code 363 was introduced to the numbering plan area in 2023, whereas area code 516 was established in 1951.

History of Area Code 516

In 1947, AT&T introduced the first nationwide telephone numbering plan. Area code 914 was assigned to Nassau, Suffolk, the lower Hudson Valley, and nearby areas in New York. By 1951, Nassau and Suffolk counties were reassigned to area code 516 due to growing demand. Despite Long Island’s population boom, this setup remained for decades.

In 1999, Suffolk split off into area code 631, while Nassau retained 516. By October 2021, ten-digit dialing became mandatory after 988 was designated for the National Suicide Prevention Lifeline, creating a conflict with existing exchanges.

In 2021, an analysis projected area code 516 would run out of numbers by 2023. To address this, area code 363 was introduced as an overlay to 516, officially activated on January 20, 2023.
