History of 707 Area Code
The 707 area code was established in 1959 as a split from 415 to serve northern and coastal California, including the North Bay, Wine Country, and nearby coastal areas. In 1997, the 916 area code was split to create 530, and communities like Dixon were moved into 707 as part of the planning process.
To accommodate growing demand for phone numbers, the 369 overlay was introduced in 2023, providing additional numbers without changing existing ones. Separately, ten-digit dialing became mandatory in October 2021 to support the nationwide 988 Suicide & Crisis Lifeline, ensuring local calls could be completed alongside this new system.

How Does a 707 Phone Number Work for Your Business?
If you are expanding your business across Santa Rosa and the North Coast, a 707 area code phone number helps your business appear as a professional local company. You can simply connect with local customers in the region remotely without needing a physical office.
In the 707 region, 10-digit dialing (area code + phone number) is mandatory for all local calls. While long-distance calls within the U.S. are made by adding a leading 1 before the 10-digit number. However, international callers can reach local lines by dialing their country’s exit code, followed by the U.S. country code 1 and the 707 number.
Major carriers operate in the region, including Pacific Bell (AT&T), Verizon, and T-Mobile. Businesses can obtain 707 phone numbers through these local providers or use VoIP services to access features like auto-attendant and call forwarding for seamless business communication across Northern California.
