History of the 363 Area Code
Area code 363 was introduced in January 2023 as an overlay to the 516 area code, which had served Nassau County since 1951. As Long Island’s population grew and demand for mobile and business numbers surged, the overlay became necessary to ensure a steady supply of new phone numbers. Today, both 363 and 516 serve as identifiers for one of New York’s most economically active regions.
