Area code 707 spans a broad region of Northern California, including cities such as Santa Rosa, Vallejo, Napa, and Eureka. Established in 1959 as a split from area code 415, 707 serves the North Coast and parts of the Wine Country and Redwood Empire. It includes iconic wine-producing regions like Napa and Sonoma, as well as scenic coastal towns and forested areas. Due to increasing demand, area code 369 was approved as an overlay in 2023, introducing mandatory ten-digit dialing. The 707 area is known for its natural beauty, agriculture, and tourism. It plays a crucial role in California’s wine economy and is a destination for visitors worldwide. Despite changes, 707 continues to symbolize Northern California’s rural charm and sophisticated appeal.
