Area code 707

Area code 707 serves California, including Santa Rosa, Fairfield-Suisun and Vallejo (Pacific time). It has been in service since January 1, 1959 and shares its area with 369.

Numbers starting with 707 drew 3,244 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 865 complaints to the FCC since November 2023. The number on your screen can be faked, so a 707 number proves nothing about where a call came from.

Phone companies holding 707 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.
