Area code 363

Area code 363 serves New York, including Nassau Zone 02, Nassau Zone 05 and Nassau Zone 07 (Eastern time). It has been in service since January 20, 2023 and shares its area with 516.

Numbers starting with 363 drew 79 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 37 complaints to the FCC since November 2023. The number on your screen can be faked, so a 363 number proves nothing about where a call came from.

Phone companies holding 363 exchanges
