History of Area Code 369
Area code 369 entered service on February 1, 2023, as an overlay for area code 707. It was not created by splitting Santa Rosa into a separate calling region. Area code 707 began service in 1959 after a split from area code 415.
The overlay added new telephone number capacity without requiring customers with existing 707 numbers to change their numbers. The change responded to growing demand for mobile phones, business lines, internet-based services, and other connections across the region.
