707 as an Overlay of 415
Area code 707 is an overlay of area code 415, meaning the two codes share the exact same geographic territory in Northwestern California — North Bay, Wine Country, and North Coast from the San Francisco Bay fringe to the Oregon border. When 707 was activated in March 1, 1959, all existing 415 phone numbers stayed unchanged. New phone lines in the region may now be assigned either 415 or 707, and ten-digit dialing is required for all local calls.

About the 707 Code
Area code 707 was carved out of 415 on March 1, 1959, when post-war population growth pushed northern California past what a single code could serve. It became California’s eighth area code and the last new one in the state until 619 arrived in 1982. For more than six decades 707 kept its original boundaries unchanged — a distinction that makes it the longest-lived unaltered area code in California. When area code 530 split from 916 in 1997, the Dixon area was folded into 707, its only geographic adjustment. Explosive mobile-phone and VoIP growth finally exhausted the prefix pool, and the CPUC approved an all-services overlay on June 23, 2022 through Decision 22-06-031; the 369 overlay took effect February 1, 2023, mandating ten-digit dialing throughout the region.
The 707 carries strong regional identity across NorCal. Vallejo rapper E-40, one of the Bay Area’s most prominent hip-hop figures, released the track “707” in 2014 with Willie Joe and Nef the Pharaoh as a direct salute to the code and its communities. Santa Rosa is home to the Charles M. Schulz Museum — Schulz lived and worked in the city from 1969 until his death in 2000, and Peanuts character statues are a fixture of downtown streets. The region also provided the real-world backdrop for Alfred Hitchcock’s 1943 film Shadow of a Doubt, shot largely in Santa Rosa. Beyond pop culture, the 707 is synonymous with Napa Valley and Sonoma wine country, old-growth redwood forests in Humboldt and Del Norte counties, and the historic Mare Island Naval Shipyard in Vallejo.

How to Get a 707 Phone Number
There are three ways to get a phone number with the 707 area code, each suited to a different need:
- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 707 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Browse our 707 inventory.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 707 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 707 number. If you already have a 707 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of California sometimes can’t accept inbound ports of 707 numbers due to 911 routing rules.

Can I get a 707 number if I don't live in California?

Is 707 a scam area code?
No. 707 is a legitimate, active area code for Northwestern California — North Bay, Wine Country, and North Coast from the San Francisco Bay fringe to the Oregon border. Like any area code, scammers occasionally spoof 707 caller IDs, but the code itself is heavily used by real California businesses, government offices, and residents.
What cities are in the 707 area code?
The 707 area code covers Santa Rosa, Vallejo, Napa, Fairfield, Vacaville, Petaluma, Eureka, Ukiah, Crescent City, Healdsburg, and dozens of other cities across ten counties in northwestern California.
Does the 707 area code require ten-digit dialing?
Yes. Ten-digit dialing (area code + seven-digit number) has been mandatory since October 24, 2021, because the 369 overlay shares the same geographic territory. All local calls within the 707/369 region require the full ten digits.
When did the 369 overlay start, and why was it added?
Area code 369 became effective February 1, 2023, after the CPUC approved the overlay on June 23, 2022. It was added because the 707 prefix pool was projected to be exhausted by late 2023 due to population growth and the proliferation of mobile and VoIP lines.
Is 707 one of California's original area codes?
No. It was split from the original 415 code on March 1, 1959 — California’s eighth area code at the time. It is not one of the three codes assigned to California in the original 1947 NANP rollout.
