Area code 657

Area code 657 serves California, including Anaheim, Huntington Beach and Santa Ana (Pacific time). It has been in service since September 23, 2008 and shares its area with 714.

Numbers starting with 657 drew 1,053 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 346 complaints to the FCC since November 2023. The number on your screen can be faked, so a 657 number proves nothing about where a call came from.

Phone companies holding 657 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% 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.
