California DBA Search
A DBA (“doing business as”) lets a business operate under a name different from its legal name. In California, DBAs are filed at the county level — here is how to search them.

A DBA (“doing business as”) is a fictitious business name — the name a business operates under when it differs from its legal registered name. Unlike corporations and LLCs, DBAs are filed at the county level, not with the Secretary of State. That means a DBA search works a little differently: you start with the state database to find the legal entity, then check the county where the business operates for the fictitious name filing.
What Is a DBA in California?
A DBA — also called a fictitious business name (FBN) — is a trade name a business uses that differs from its legal registered name or the owner’s personal name. California law (Business and Professions Code §17900) requires businesses to file a fictitious business name statement with the county where they operate.
Common examples:
- A sole proprietor named Maria Lopez trading as “Lopez Family Catering”
- An LLC called “Golden State Holdings LLC” running a shop named “Bayview Books”
- A corporation operating multiple brands under different trade names
Key point: DBAs are not in the Secretary of State’s statewide database. They are recorded by each of California’s 58 counties. That is why a DBA search is different from a company search.
How to Search California DBA Records
- Figure out the county. DBA statements are filed in the county where the business’s principal place of business is located. If you know the city, you know the county.
- Use the county’s FBN search. Most populous counties offer a free online fictitious business name search on the county clerk’s website.
- Search the trade name. Enter the business name the public sees. Results typically show the legal owner or entity behind the name.
- Check the state database too. If the DBA belongs to an LLC or corporation, you can then pull the full entity record on bizfile Online.
Where to Search by County
Start with the county clerk or registrar where the business operates. Some of the most searched counties:
| County | Where to search |
|---|---|
| Los Angeles | LA County Registrar-Recorder/County Clerk — Fictitious Business Name search |
| San Diego | San Diego County Clerk — Fictitious Business Name lookup |
| Orange | Orange County Clerk-Recorder — FBN search |
| Riverside | Riverside County Clerk — Fictitious Business Name search |
| San Bernardino | San Bernardino County Clerk — FBN records |
| Santa Clara | Santa Clara County Clerk — FBN search |
| Alameda | Alameda County Clerk-Recorder — FBN search |
| Sacramento | Sacramento County Clerk — Fictitious Business Name search |
| San Francisco | San Francisco Office of the Assessor-Recorder — FBN search |

DBA Filing Basics
- Where filed: the county clerk/recorder of the business’s principal county
- Publication: after filing, the statement must be published in a newspaper of general circulation for 4 weeks
- Expiry: a fictitious business name statement expires 5 years after filing and must be renewed
- Protection: a DBA does not create a legal entity and does not by itself grant exclusive rights to the name

Why Search a California DBA?
A DBA (“doing business as”) is a fictitious business name — the name a business operates under when it differs from its legal registered name. Because DBAs are filed at the county level rather than with the Secretary of State, searching for them works differently. Here are the most common reasons people search for a DBA:
- Find the legal entity behind a trade name. If you see a business name in the marketplace, a DBA search helps you find the actual company or person behind it.
- Verify a business before paying. Confirm the trade name is registered and find the legal entity that owns it.
- Check whether a name is in use. Before you file your own DBA, see if the name is already taken in your county.
- Research competitors. See what trade names competitors operate under in your area.
Where DBAs Are Filed
Unlike corporations and LLCs, which are registered with the Secretary of State, DBAs are filed with the county clerk in the county where the business operates. This means there is no single statewide database for DBAs. Each of California’s 58 counties maintains its own fictitious business name records.
To search for a DBA, you typically need to know which county the business operates in. Start with the county clerk’s website or office for that county. Many counties offer online search tools.
Start with the state database. Even though DBAs are filed at the county level, the legal entity behind a DBA is often a corporation or LLC registered with the Secretary of State. Search the state database first to find the entity, then check the county for the DBA filing.
How to Search for a DBA
- Search the state database first. Look up the trade name in the Secretary of State’s business search. If the business is a corporation or LLC, you may find it here.
- Identify the county. If the business operates under a DBA, find out which county it operates in. This is usually where the DBA is filed.
- Search the county’s records. Visit the county clerk’s website or office and search their fictitious business name database.
- Review the filing. A DBA filing shows the trade name, the legal name of the owner or entity, and the business address.
What a DBA Filing Shows
A fictitious business name statement typically includes:
| Field | What it tells you |
|---|---|
| Fictitious business name | The trade name the business operates under. |
| Legal name of owner/entity | The actual person or registered entity behind the trade name. |
| Business address | The principal place of business. |
| Owner details | For sole proprietors, the owner’s name and address. |
| Filing date | When the DBA was registered with the county. |
DBA vs. LLC vs. Corporation
A DBA is not a legal entity — it is just a name. Here is how it compares to forming an LLC or corporation:
| Feature | DBA | LLC / Corporation |
|---|---|---|
| Legal entity | No | Yes |
| Liability protection | No | Yes |
| Filed with | County clerk | Secretary of State |
| Name protection | County only | Statewide |
| Typical cost | $40–$60 | $70–$100 + annual fees |
For statewide name protection, consider forming an LLC or corporation and using a DBA only for an additional trade name. A DBA alone does not protect your name outside the county where it is filed.
How Long Does a DBA Last?
A California fictitious business name statement expires after five years. If you want to keep using the name, you must renew it before it expires. Here is the renewal timeline:
| Event | When | What to do |
|---|---|---|
| Initial filing | When you start using the name | File the Fictitious Business Name Statement with the county clerk |
| Publication | Within 30 days of filing | Publish the statement in a newspaper of general circulation for 4 weeks |
| Proof of publication | After publication | File the affidavit of publication with the county clerk |
| Renewal | Before the 5-year expiration | File a renewal statement to keep the name active |
| Abandonment | When you stop using the name | File a statement of abandonment (optional but recommended) |
Don’t let it lapse: if your DBA expires and you keep using the name, you lose the legal protection of the filing. Another business could register the same name. Set a reminder to renew before the five-year mark.
Searching DBAs in Major California Counties
Because DBAs are filed at the county level, you search them through each county’s clerk office. Here are the largest counties and where to search:
- Los Angeles County. The Registrar-Recorder/County Clerk maintains fictitious business name records. Search online through the county’s portal.
- San Diego County. The County Clerk’s office handles DBA filings and offers an online search.
- Orange County. The Clerk-Recorder maintains fictitious business name records with online search available.
- Riverside County. The County Clerk handles DBA filings.
- San Bernardino County. The County Clerk maintains fictitious business name records.
- Sacramento County. The County Clerk handles DBA filings and offers search tools.
Each county has its own fees, forms, and search tools. If you are researching a DBA, start by identifying the county where the business operates, then visit that county’s clerk website.
DBA Publication Requirements Explained
One of the most misunderstood parts of filing a DBA in California is the publication requirement. Here is how it works in detail:
- File the statement first. You file the Fictitious Business Name Statement with the county clerk and pay the filing fee.
- Publish within 30 days. Within 30 days of filing, you must publish the statement in a newspaper of general circulation in the county where the business operates.
- Publish for four consecutive weeks. The statement must run once a week for four weeks in a row.
- File proof of publication. After publication, the newspaper provides an affidavit. You file this affidavit with the county clerk to complete the process.
The purpose of publication is to give the public notice of who is operating under the trade name. If you skip this step, your DBA filing is not fully effective, and you may have trouble enforcing rights to the name.
DBA Costs by County
DBA fees vary by county, but here is a general idea of what to expect:
| Cost item | Typical range | Notes |
|---|---|---|
| Filing fee | $40–$60 | Varies by county; some charge extra for additional names or owners |
| Publication | $30–$150 | Depends on the newspaper and the length of the statement |
| Renewal fee | $40–$60 | Every 5 years |
| Certified copy | $5–$15 | If you need an official copy of the filing |
Because fees and procedures differ by county, always check the specific county clerk’s website before you file. Some counties allow online filing and payment, while others require in-person or mail submission.
Common DBA Mistakes to Avoid
- Not publishing the statement. Filing alone is not enough — you must complete publication and file the proof.
- Letting the DBA expire. DBAs expire after five years. Set a reminder to renew before expiration.
- Assuming statewide protection. A DBA only gives notice in the county where it is filed. For statewide protection, form an LLC or corporation.
- Using a DBA instead of forming an entity. A DBA provides no liability protection. If you want protection, form an LLC or corporation.
- Forgetting to update the DBA. If your business address or ownership changes, you may need to file an amended statement.
Research tip: when investigating a business that uses a trade name, search both the state database (for the legal entity) and the county records (for the DBA). Together they give you the full picture of who is behind the business.
Frequently Asked Questions
Why can’t I find a DBA in the state search?
Because DBAs are county records, not state records. The Secretary of State database only contains registered entities like LLCs and corporations. Use the county search for the business’s county instead.
Is a DBA search free?
Most counties offer free online FBN searches. Some charge a small fee for certified copies or in-person research.
Can I find who owns a business from a DBA?
Yes — that is the main purpose of the filing. The FBN statement lists the legal owner (a person or an entity) behind the trade name.
What if I don’t know the county?
Start with the city where the business operates and identify its county. If the business has a website, its contact page or terms often list the legal entity, which you can then verify in the state database.
Is a DBA the same as a business license?
No. A DBA (fictitious business name) registers the name you operate under. A business license is permission from a city or county to operate a business in that jurisdiction. You may need both. A DBA does not replace a business license.
Can I have more than one DBA?
Yes. A business can register multiple fictitious business names. Each one requires its own filing and publication. This is common for businesses that operate different brands or product lines under different names.
Need the entity behind a DBA?
Once you know the legal name, pull its full record on the official state database.
