Area code 909

Area code 909 serves California, including Ontario, San Bernardino and Fontana (Pacific time). It has been in service since November 14, 1992 and shares its area with 840.

Numbers starting with 909 drew 2,326 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 678 complaints to the FCC since November 2023. The number on your screen can be faked, so a 909 number proves nothing about where a call came from.

Phone companies holding 909 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 71% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
