To run a California fictitious business name search by county, go to the county clerk’s office (or its website) where the business will have its principal place of business, because FBN records are kept county by county with no statewide database.1California Legislative Information. California Code BPC – Fictitious Business Names That county search is the first layer. To actually clear a name before you print cards or build a website, you also need to search the Secretary of State’s business entity database and the federal trademark register.
Which County to Search
You file your FBN in the county where your business has its principal place of business, and that is the county you search first. For a sole proprietor working from home, that is the county where you live. For a business with a storefront or office, it is the county where that location sits. If you have no place of business in California at all, filings go to the Sacramento County Clerk.2California Legislative Information. California Business and Professions Code 17915
California has 58 counties, and each maintains its own independent FBN records. A name can be available in Los Angeles County and already taken in San Diego County. County clerks do not cross-reference with other counties, and most will not reject a duplicate filing even within their own records. Sacramento County, for example, states that it will file any properly completed FBN statement and does not check whether the same name is already on file.3Sacramento County Department of Finance. Sacramento County Fictitious Business Name FAQ The screening is on you.
If you plan to operate in neighboring counties as well, search those counties too. A match there will not block your filing at home, but it will create customer confusion and set up a potential dispute down the road.
How to Run the County Search
The office that handles FBN records goes by different names in different places. You will see County Clerk, County Recorder, and Assessor-Recorder-County Clerk. The process is similar everywhere.
Online
Most California counties offer a free online FBN search on the county clerk’s website. Los Angeles County publishes its filed names through an open data portal.4County of Los Angeles Open Data. LA County Fictitious Business Names Fresno County has its own search page.5Fresno County Clerk. Fictitious Business Name Search These tools usually let you search by business name or by registrant name. Run the exact name you want and then run partial variations. “Golden State Landscaping” and “Golden State Landscape Services” are separate filings, but either one would cause you problems if the other already existed.
Online databases generally cover recent filings rather than the full historical record. If you need older records, plan on an in-person visit or a mail search.
In person or by mail
A basic name check at the counter is usually free. Staff will look up a specific name and tell you whether it is currently on file. A more formal search by mail usually carries a small fee. Include the exact business name and, if you have it, the registrant’s name. Results typically show the business name, the filing date, and owner information for any matches.
Also Search the Secretary of State’s Business Database
A county FBN search only covers trade names filed in that one county. It tells you nothing about corporations, LLCs, limited partnerships, or other entities registered with the state. Those entities file their legal names with the California Secretary of State, which keeps a separate database.6California Secretary of State. Business Entities
You can search those records for free using the Business Search tool at bizfileonline.sos.ca.gov. Enter your proposed name and look for entities with the same or confusingly similar names. An FBN is a public notice of a trade name; it does not carry the same legal weight as a formally registered business entity. If an LLC already holds a name close to the one you want to use, that LLC has the stronger claim.
Then Search the Federal Trademark Database
A name can be clear at the county level and clear at the state level and still belong to a federal trademark holder with superior rights across the entire country. An FBN filing gives you no trademark protection, and neither does a state entity registration.
Before you commit, search the U.S. Patent and Trademark Office’s free online trademark database at tmsearch.uspto.gov.7United States Patent and Trademark Office. Trademark Search Look for identical matches and for phonetic look-alikes. A registered federal trademark in your industry will beat your FBN filing regardless of when either one was filed. If you find a conflict, pick a different name. Rebranding later costs far more than choosing differently now.
What a Clean County Search Actually Gets You
A county FBN filing does not give you ownership of the name in any absolute sense. It gives you a rebuttable presumption of exclusive rights to the name within the county where you filed, and only if you were the first to file it there and you are actually using the name in business.8California Legislative Information. California Business and Professions Code 14411 “Rebuttable” means another party can still challenge your right to the name if they can show a stronger claim, such as prior use or a federal trademark.
Because the clerk will not refuse a duplicate, your filing date is your evidence of priority. That is a real reason to search carefully and file promptly, but it is a thin shield compared to a federal trademark registration.
After the Name Clears
Once the name is clear in all three places, file the FBN statement with the county clerk where your principal place of business is located. You have 40 days from the date you start doing business under the name to file.9California Legislative Information. California Business and Professions Code 17910 Filing fees vary by county and generally fall in the range of $26 to $40 for one business name and one registrant.
Filing is only half of it. California also requires you to publish the statement in a newspaper of general circulation in the county where you filed. Publication must start within 45 days of filing and run once a week for four consecutive weeks.10California Legislative Information. California Business and Professions Code 1791711California Legislative Information. California Government Code 6064 After publication finishes, you have another 45 days to file the affidavit of publication back with the county clerk. The newspaper usually handles the affidavit as part of its publication fee, which often runs between $30 and $80.
The statement itself expires five years from the filing date, so your clean search today buys you a five-year runway on the name before you have to refile.1California Legislative Information. California Code BPC – Fictitious Business Names
Why Skipping the Filing Backfires
The penalty for operating under a fictitious name without a proper filing is not a fine. It is a loss of standing to sue. Under BPC section 17918, a person doing business under a fictitious name without a properly filed and published FBN statement cannot maintain a lawsuit on any contract or transaction conducted under that name.12Justia Law. California Business and Professions Code 17900-17930 If a client refuses to pay a $50,000 invoice and your FBN is not on file, you cannot sue to collect until you cure the filing. You can fix it by filing and publishing, and your right to sue is then restored, but the delay is the kind of risk no business should take on by choice.
