Origin Story
Area code 408 was established in June 1959 when it was split from the original 415 area code, which had covered much of Northern California. This creation coincided with the early growth of the Santa Clara Valley, then known as the 'Valley of Heart's Delight' for its orchards. The area code's boundaries were significantly reduced in 1998 with the creation of area code 831, which took Monterey and Santa Cruz counties. In 2012, due to the explosive demand from the tech boom, 408 received its first overlay, area code 669. Today, 408 and 669 serve the same geographic area, covering most of Santa Clara County and parts of Northern Santa Cruz County, including cities like San Jose, Sunnyvale, Santa Clara, Gilroy, and Los Gatos. The code has evolved from representing agricultural lands to being the digital identity of Silicon Valley.
