Area code 951

Area code 951 serves California, including Riverside, Corona and Temecula (Pacific time). It has been in service since July 17, 2004.

Numbers starting with 951 drew 1,636 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 716 complaints to the FCC since November 2023. The number on your screen can be faked, so a 951 number proves nothing about where a call came from.

Phone companies holding 951 exchanges
