What this is
A business operating in Sonoma County under a name other than its owner's files a fictitious business name statement with the County Clerk, valid five years. This site keeps the companies — names that carry Inc, LLC, Corp and the like — and makes them searchable by name, type and place.
Who uses it
- Suppliers and landlords — is this company in the Sonoma County file, and since when?
- Sales teams — companies by type and place, and the newest ones.
- Owners — your own record as the source publishes it.
What it is not
Not the County of Sonoma, and not a certificate. Individuals and names without a company word are left out. The registrant's name is never shown, and business names without a company word are left out.
