To run a California fictitious business name search by county, go directly to the county clerk (or recorder, depending on the county) where the business has its principal place of business, because California keeps FBN records at the county level and has no statewide search tool.1California Legislative Information. California Code BPC – Fictitious Business Names Most counties now offer a free online search. A county check is the first layer, but not the only one: to actually clear a name for use, you also search the Secretary of State’s entity database and the federal trademark register.
Why the Search Is County-by-County
California has 58 counties, and each maintains its own independent FBN records. There is no unified statewide database, and county clerks don’t cross-reference filings with other counties.1California Legislative Information. California Code BPC – Fictitious Business Names A name can be available in Los Angeles County and already in use in San Diego County, and neither clerk will tell you about the other.
Most clerks won’t even screen duplicates within their own records. Sacramento County states plainly that it will file any properly completed FBN statement and does not check whether the same name is already on file.2Sacramento County Department of Finance. Sacramento County Fictitious Business Name FAQ The clerk’s office is a filing agency, not a name-clearance service. The searching is on you.
Which County to Search First
Start with the county where the business has its principal place of business. For a sole proprietor working from home, that’s the county of residence. For a company with a storefront or office, it’s the county where that location sits. A business with no place of business in California at all files with the Sacramento County Clerk.3California Legislative Information. California Business and Professions Code 17915
If you plan to operate across county lines, searching each of those counties is worth the effort. Another business already using the name in a neighboring county won’t legally block your filing at home, but it invites confusion and disputes with customers who see both names in the same market.
How to Run the County Search
The office that keeps the records goes by different titles across the state. In some counties it’s the County Clerk, in others the County Recorder or the Assessor-Recorder-County Clerk. The process is similar wherever you land.
Online
Most California counties now publish a free online FBN search on the clerk’s website. Los Angeles County offers a searchable database through its open data portal.4County of Los Angeles Open Data. LA County Fictitious Business Names Fresno County provides its own online search page.5Fresno County Clerk. Fictitious Business Name Search These tools usually let you search by business name or by registrant name.
Search the exact name you want, then run variations. “Golden State Landscaping” and “Golden State Landscape Services” are separate filings that can still cause confusion in the market. Online databases generally cover recent filings rather than the complete historical record, so if you need older records you may have to visit the office or request a mail search.
In Person or by Mail
Walking into the clerk’s office for a basic name check is usually free. Staff will look up a specific name and tell you whether it’s currently on file. Many county clerks also accept mail requests for a formal search, typically for a small fee. Include the exact business name you want checked and, if you have it, the registrant’s name. Results normally show the business name, filing date, and owner information for any match.
The Two Searches You Can’t Skip After the County Check
A county FBN search only covers trade names filed in that county. It says nothing about corporations, LLCs, or limited partnerships registered with the state, and nothing about federally registered trademarks. Clearing a name means running all three searches.
California Secretary of State
Corporations, LLCs, and other registered entities file their legal names with the California Secretary of State, in a database separate from any county’s FBN records.6California Secretary of State. Business Entities You can search those records for free at bizfileonline.sos.ca.gov. Look for the same or confusingly similar names. An FBN is a public notice of a trade name; it doesn’t carry the same legal weight as a registered entity. If an LLC already holds a similar name, that LLC has the stronger claim, and the FBN filing won’t save you from a cease-and-desist letter after the business cards are printed.
Federal Trademark Register
This is where new business owners often get caught. A name can be clean at the county and state level and still collide with a federal trademark holder whose rights run nationwide. An FBN filing gives no trademark protection at all, and neither does a state entity registration.
Before committing, search the U.S. Patent and Trademark Office’s free trademark database at tmsearch.uspto.gov.7United States Patent and Trademark Office. Trademark Search Check for identical matches and phonetic near-matches. A registered federal trademark in your industry beats an FBN filing regardless of filing dates. If a conflict shows up, pick a different name. Rebranding later costs far more than choosing again now.
What a Winning County Search Actually Buys You
Filing an FBN after a clean county search doesn’t give you ownership of the name outright. It gives you a rebuttable presumption of exclusive rights to the name inside the county where you filed, provided you were the first to file it there and you’re actually using it in business.8California Legislative Information. California Business and Professions Code 14411 Another party can still challenge that presumption by showing a stronger claim, such as prior use or a registered trademark.
Because the clerk won’t reject a duplicate, filing early matters. If someone else files the same name in your county later, the clerk will process it anyway, and your earlier filing date is what establishes priority. That county-level presumption is a thin shield next to a federal trademark, which is why the USPTO search belongs in every name-clearance workflow.
Why the Search Is Worth Doing Carefully
The penalty for operating under a fictitious name without a properly filed and published FBN statement isn’t a fine. It’s the loss of your right to sue. Under BPC section 17918, a person doing business under a fictitious name without a properly filed and published statement cannot maintain a lawsuit on any contract or transaction conducted under that name.9Justia Law. California Business and Professions Code 17900-17930 If a client refuses to pay a $50,000 invoice and the FBN isn’t on file, you can’t sue to collect until you cure the filing. Banks will also typically refuse to open a business account under a fictitious name without a filed FBN statement.
The county search protects you on the front end. Running it, along with the state and federal searches, is the only way to know the name is worth filing at all.
