The area code 369 is located in santa rosa, California.
Area code 369 serves Santa Rosa, California, as an overlay to the long-standing 707 area code, covering the North Bay and North Coast. It was introduced for new phone numbers on February 1, 2023, to keep up with demand across Sonoma, Napa, Solano, Mendocino, Humboldt, Lake, and nearby counties. Santa Rosa—the largest city in Sonoma County and a gateway to Wine Country—anchors this region with landmarks like the Charles M. Schulz Museum and Annadel State Park. With the overlay, 10-digit dialing is required for local calls, but existing 707 numbers did not change.
Major cities and communities in the 707/369 overlay include:
This broad footprint stretches from vineyards in Napa and Sonoma to the rugged Redwood Coast along Highway 1 and U.S. 101. The overlay keeps the same geographic boundaries as 707, so calls within the region work the same—only the area code on new numbers may be different. Santa Rosa’s central location—about an hour north of San Francisco—makes it a hub for business, tourism, and wine production, all supported by growing phone number needs. “Customers will use 10-digit dialing for local calls, and existing numbers will not change,” — California Public Utilities Commission (CPUC).
