408 Area Code
for San Jose Businesses

The 408 area code serves San Jose, California and Silicon Valley, covering Santa Clara County and parts of Santa Cruz, Monterey, and San Benito counties. Established in 1959, it's the telecommunications hub for America's technology capital.

The 408 area code was established in June 1959 as the first split from the original 415 area code, which had covered the entire San Francisco Bay Area since the North American Numbering Plan began in 1947. This split recognized the rapid growth of Santa Clara County and the emerging technology industry that would become known as Silicon Valley. The region's transformation from agricultural orchards to the world's technology capital drove unprecedented demand for telephone numbers. By 1998, the southern portions of the 408 territory (Santa Cruz, Monterey, and San Benito counties) were split off to create area code 831. As Silicon Valley continued its explosive growth with the dot-com boom and mobile revolution, number exhaustion became imminent. In November 2012, the 669 overlay code was introduced, creating a complex where new numbers could be assigned from either 408 or 669. Today, the 408/669 complex serves the heart of Silicon Valley, home to global technology giants including Apple, Google, Intel, Cisco, and thousands of startups that continue to drive innovation and demand for telecommunications services.
