History and Evolution of Area Code 408
The area code 408 was introduced on January 1, 1947, as one of the original 86 area codes in the North American Numbering Plan (NANP). Initially, it served the entire central coast of California, from the San Francisco Bay Area to the Monterey Bay area. However, due to the rapid growth of the region, particularly in the technology sector, the area code 408 became one of the first to be split. In 1998, area code 831 was created to serve the Monterey Bay area, reducing the geographic scope of the 408 area code. Later, in 2012, area code 669 was introduced as an overlay to the 408 area code, allowing for more phone number combinations in the same geographic region.
