Want to build credibility in one of the most innovation-driven markets in the world? A 408 area code gives your business instant recognition in San Jose, Santa Clara, Cupertino, and other communities across Santa Clara County.
Located in the State of California, this region is home to Silicon Valley’s leading technology companies and startups.
However, new 408 numbers are no longer widely available due to limited supply. If you already own a 408 number, you can port it to DialLink. If not, overlay code 669 serves the same region and provides additional numbers for businesses.
With DialLink, you can activate a local number in minutes and manage your entire business phone system through our intuitive platform without expensive hardware or technical complexity.
Why Choose a 408 Area Code?
The 408 area code is a well-known identifier for Silicon Valley. It covers major cities in Santa Clara County, including San Jose, Santa Clara, Campbell, Saratoga, Sunnyvale, and Los Gatos.
The region plays a major role in global technology, making the 408 area code one of the most recognizable identifiers in the tech industry.
As the population and business activity in Silicon Valley grew, demand for phone numbers increased. To support the region’s telephone numbering needs, telecom authorities introduced area code 669 as an overlay in 2012.
Both codes now serve the same geographic area. Businesses in the region must dial using ten digit dialing for local calling, a standard requirement across the area.
Choosing a number with either code helps your business align with one of the most influential markets in the State of California.
