No Office Needed

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 the broader Silicon Valley area. However, due to limited availability, new 408 numbers are no longer being issued. If you already own a 408 number, you can easily port it to DialLink. If not, overlay code 669 is available and serves the exact same region.
With DialLink, you can activate a local number in minutes and manage your entire business phone system through our intuitive, AI-powered platform — without expensive hardware or technical overhead.

Why Choose a 408 Area Code?

The 408 area code is a well-known identifier for California’s tech capital, covering major cities like San Jose, Santa Clara, Campbell, Saratoga, and parts of Sunnyvale. It’s one of the most recognized area codes in the tech world used by early-stage startups, venture-backed companies, and global enterprises alike.
Due to the high demand for local numbers, the 669 area code was added as an overlay in 2012. Both codes now serve the same geographic area, and choosing either ensures your business is locally aligned with one of the most prestigious markets in the U.S.
