Area code 661

Area code 661 serves California, including Bakersfield, Palmdale and Santa Clarita (Pacific time). It has been in service since February 13, 1999.

Numbers starting with 661 drew 1,509 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 508 complaints to the FCC since November 2023. The number on your screen can be faked, so a 661 number proves nothing about where a call came from.

Phone companies holding 661 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 79% 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.
