About 707 Area Code
Area code 707 serves Northwestern California and the North Bay region. Created in 1959 when it split from area code 415, 707 is California's longest-lasting area code with unchanged boundaries. It covers Santa Rosa, Vallejo, Napa, Fairfield, Vacaville, Eureka, and dozens of smaller communities across Sonoma, Napa, Solano, Mendocino, Humboldt, and several other counties. The code supports local voice and SMS-capable numbers used by wineries, hospitality businesses, healthcare providers, and agricultural operations.
The 707 region centers on world-famous wine country, with Napa and Sonoma counties driving billions in tourism revenue annually. Local businesses use 707 numbers for winery reservations, hotel bookings, tour coordination, and agricultural supply chains. A local area code signals credibility in a market where personal connection and regional authenticity matter. Answer rates jump when customers recognize familiar local numbers instead of toll-free or out-of-area alternatives.
FoneSwift lists live 707 inventory with Voice, SMS, and MMS capabilities on this page. In February 2023, area code 369 was added as an overlay, meaning new numbers in the same region may receive either 707 or 369. If 707 numbers are limited, consider nearby codes like 415, 510, or 925 to maintain strong Bay Area and Northern California presence.
If you're targeting wine country or the North Bay, format your 707 numbers in both local style (707) 555-1234 and international E.164 format +1 707 555 1234. Register A2P messaging if you plan business SMS campaigns. For number porting, check our porting guide. Many hospitality and tourism businesses keep their existing numbers when switching providers to preserve brand recognition and customer familiarity.

California's longest-lasting area code
Area code 707 has maintained the same geographic boundaries since 1959, making it the longest-lasting area code in California without a split or major boundary change.
Split from 415
Created on January 1, 1959, the 707 area code was California's eighth area code and resulted from splitting the northern portion from the original 415 area code that covered the Bay Area.
Wine country epicenter
The 707 region includes Napa and Sonoma counties, which together represent one of the world's most prestigious wine regions. Tourism generates billions in annual visitor spending across wine country.
Recent overlay addition
In February 2023, area code 369 was added as an overlay to 707, meaning both codes now serve the exact same geographic area. This was the first overlay in the San Francisco Bay Area.
Rotary phone legacy
When 707 launched in 1959, rotary phones required 24 pulses to dial. Area codes with fewer pulses were prioritized for larger cities, showing 707 served less densely populated regions initially.

How Does Local 707 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 707 number in Santa Rosa and California, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (707): directs the call to the Santa Rosa / California region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 707 555 1234 |
| Local Format (National) | (707) 555-1234 |
