Area code 323

Area code 323 serves California, including Los Angeles and Montebello (Pacific time). It has been in service since June 13, 1998 and shares its area with 213 and 738.

Numbers starting with 323 drew 1,569 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 900 complaints to the FCC since November 2023. The number on your screen can be faked, so a 323 number proves nothing about where a call came from.
