Area codes 408 and 669


Area code 408 is a California telephone area code that was split from area code 415 as a flash-cut in 1959. Area code 669 is an overlay of 408 that became effective on November 20, 2012. It covers most of Santa Clara County and Northern Santa Cruz County and includes Gilroy, Morgan Hill, Saratoga, Los Gatos, Monte Sereno, Milpitas, Sunnyvale, Santa Clara, Cupertino, and San Jose.

On July 11, 1998, it was split again, with area code 831 having been created for the counties of Santa Cruz, Monterey, and San Benito. Despite this split, the 408 area code is still used in northern Santa Cruz County.

On November 20, 2012, numbers in a new overlay area code 669 began to be assigned to new customers, requiring the use of ten-digit dialing in the entire area.

Los Gatos is one of three cities in Santa Clara County that was not served by the Bell System. Gilroy and Morgan Hill were also outside the Regional Bell Operating Company (RBOC) service area. These communities were served by what was referred to, in "Bell System circles", as "independent" telephone companies.
