Sonoma County offender search FAQ
How many registered sex offenders are in Sonoma County?
As of August 2026, we index approximately 604 registrants with a Sonoma County, CA address — about 12.4 per 10,000 residents, or about 1 in 809 residents. Treat the figure as scale rather than a fixed number: the registered population moves continuously as people are added, move, or are released from the requirement. When you need an answer about a specific person, run a search.
How does Sonoma County compare with the rest of California?
Sonoma County sits at about 12.4 registrants we index per 10,000 residents, against a California average of about 15.9 and a national average of about 47.2. Density varies block by block inside any county, so use the ratio as context — and a search, not an average, to answer about a specific address or person.
How do I check a specific person in Sonoma County?
Type their last name and add whatever else you hold — first name, date of birth, or narrow to a Sonoma County city or ZIP. You get scored matches with photographs and official record links, and the search covers every US registry at once, so someone now in Sonoma County who was registered elsewhere still surfaces. Your first 25 searches are free, no card required.
How do I find sex offenders near a Sonoma County address?
Search outward from a street address or ZIP within Sonoma County. Each result is the full registry record — photograph, offense history and the official state link — and you can widen the radius from one mile to a hundred to cover a neighbourhood or the whole area. It is address-and-radius search rather than a map, and it sees registrants whose published address we hold and have placed on a coordinate.
Is this the official Sonoma County sex offender registry?
Registries are maintained per state, not per county, so no single official "Sonoma County registry" list exists. What you search here is our continuously updated national dataset with every US registry in one place, and each record links back to the official state entry that published it — so you can verify any Sonoma County result at its source.
