Area code 669

Area code 669 serves California, including San Jose, Campbell and Sunnyvale (Pacific time). It has been in service since November 20, 2012 and shares its area with 408.

Numbers starting with 669 drew 660 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 212 complaints to the FCC since November 2023. The number on your screen can be faked, so a 669 number proves nothing about where a call came from.

Phone companies holding 669 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 99% 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.
