Find any 408- phone number in California
The 408 area code is a California area code that is located in the northern portions of California. This particular area code is part of the highly sophisticated North American Numbering Plan (NANP), which is used to create a geographical numbering system for North America. The plan divides the US and Canada into regions, with each region receiving a three-digit code. The 408 area code falls under the Californian region and is used to route calls for various cities located in the northern parts of the state, including San Jose, Santa Cruz, and Sunnyvale.
The prior area code for the Northern Californian cities was 415, which was established in 1947. Due to the area’s increasing population and growth in the telecommunications industry, the California Public Utilities Commission decided to create a separate area code for the northern region. As a result, the 408 area code was created in November 1998 as an overlay to the 415 area code. This allowed customers in the affected cities to retain their original area codes while allowing for growth in the telecommunications industry.
