707 Area Code: Location, Time Zone & Phone Lookup - Page 2

Area code 707 is one of the original area codes established in California in October 1947. It originally served the entire north coast of the state, from the Oregon border to San Francisco Bay. In the late 1990s, the 707 area code was split, and the code now serves only the northern coast, from the Oregon border to the Sonoma County line. The 707 area code has a rich history dating back to the late 1940s. The code got its start in October 1947, when it was one of the original area codes established in California. At the time, it served the entire north coast of the state, from the Oregon border to San Francisco Bay.

In the late 1990s, the 707 area code was split into two parts. The southern portion, including the Bay Area and Sacramento, became area code 916. The northern coast, from the Oregon border to the Sonoma County line, became area code 707.

Today, the 707 area code serves only the northern coast of the state. This includes the counties of Humboldt, Mendocino, Lake, Napa, Sonoma, and Solano.
