How to Register a Business Name in California?

Table of Contents

Last updated: July 3, 2026

To register a business name in California, first choose your business structure, then check whether your preferred name is available.

LLCs, corporations and limited partnerships register their legal business name through the California Secretary of State when filing formation documents through bizfile Online.

Sole proprietors and partnerships usually register a trade name as a Fictitious Business Name, also called an FBN or DBA, with the county clerk where the business is based.

California business entity names generally must be distinguishable in the records of the California Secretary of State and must not be likely to mislead the public.

A business name can also be reserved for 60 days before filing if you are not ready to form the entity immediately.

Does a name search guarantee approval?	No. A search helps, but the Secretary of State or county still reviews the filing.
Does registering a business name protect a trademark?	Not fully. Trademark protection is separate from entity or DBA registration.

What Does “Registering a Business Name” Mean in California?

Registering a business name in California can mean different things depending on your business structure.

For an LLC, corporation or limited partnership, the business name is usually registered when you file formation documents with the California Secretary of State.

The Secretary of State’s bizfile Online system allows business owners to file, search and order business records.

For a sole proprietorship or general partnership, the owner’s legal name may not need a state entity filing.

But if the business uses a name that is different from the legal name of the owner or partners, it usually needs a Fictitious Business Name filing with the county.

For example:

Business Situation	Likely Name Filing
Maria Lopez runs consulting as “Maria Lopez”	May not need FBN if using only legal name
Maria Lopez runs consulting as “Golden Coast Consulting”	Likely needs county FBN/DBA filing
Two partners operate as “Pacific Design Studio”	Likely needs county FBN/DBA filing
Golden Coast Consulting LLC	Register LLC name with California Secretary of State
Pacific Design Studio Inc.	Register corporation name with California Secretary of State

Business Name, DBA, FBN, LLC and Trademark: What Is the Difference?

Many new business owners confuse these terms. They are connected, but they are not the same.

Term	Meaning	Where It Is Usually Filed
Legal business name	The official name of an LLC, corporation or other entity	California Secretary of State
DBA	“Doing Business As” name used publicly	County clerk as an FBN
FBN	Fictitious Business Name, California’s common term for DBA	County clerk or county clerk-recorder
LLC name	Legal name of a limited liability company	California Secretary of State
Corporation name	Legal name of a corporation	California Secretary of State
Trademark	Brand identifier for goods or services	USPTO federally, or state trademark filing where applicable
Domain name	Website address	Domain registrar
Business licence	Permission or registration to operate locally	City, county or local agency

A California business name filing does not automatically give full trademark rights, does not replace a business licence, and does not create a website domain.

Step-by-Step: How to Register a Business Name in California

1.Choose Your Business Structure First

Before registering a name, decide how the business will operate legally. The business structure affects how the name is filed, who owns the business, tax treatment, personal liability and annual compliance.

Common California business structures include:

sole proprietorship,
general partnership,
limited liability company,
corporation,
limited partnership,
nonprofit corporation.

If you form an LLC or corporation, you will normally file with the California Secretary of State. If you operate as a sole proprietor or general partnership using a trade name, you will usually file an FBN with the county.

2.Create a Name That Meets California Naming Rules

A California business name should be clear, unique enough for filing, not misleading and suitable for your business activity.

California Secretary of State regulations say proposed corporation, LLC and limited partnership names must be distinguishable in Secretary of State records and must not be likely to mislead the public.

A good California business name should:

identify your brand clearly,
avoid copying an existing business name,
avoid implying a regulated activity unless you are authorised,
avoid suggesting a government connection,
work as a domain and social handle,
be easy to spell and remember,
not create trademark conflict.

Avoid choosing a name only because it sounds catchy. A name that is too similar to another entity, trademark or local DBA can create rejection, rebranding costs or legal risk.

3.Search the California Secretary of State Business Database

Use the California Secretary of State business search to check existing corporations, LLCs and limited partnerships. The official search lets users access records for California corporations, LLCs and limited partnerships and retrieve public filings where available.

Search for:

exact business name,
plural and singular versions,
abbreviations,
similar spellings,
punctuation variations,
words in a different order,
closely related brand names.

A business name search can show useful information such as:

Search Result Field	What It Means
Entity name	The legal name registered with the state
Entity number	The identification number assigned by the Secretary of State
Entity type	Corporation, LLC, limited partnership or other entity
Registration date	When the entity was registered
Status	Whether the entity is active, suspended, dissolved or cancelled
Agent for service of process	Person or company authorised to receive legal papers
Business address	Public address information on file
Filing history	Public documents filed with the state

Important: a business search is not a final legal clearance. It only helps you spot obvious conflicts before filing.

4.Check County Fictitious Business Name Records

If you plan to use a DBA or fictitious business name, search the FBN records in the county where your business will operate.

California fictitious business names are not handled in one central statewide business-name database in the same way as LLCs and corporations. They are generally filed locally with the county clerk or county clerk-recorder.

This matters because an LLC name available at state level may still conflict with a county DBA, trademark, domain name or competitor brand.

5.Check Trademarks Before You File

A business entity name or FBN filing does not automatically protect your brand as a trademark. The USPTO explains that its trademark resources allow users to search trademarks, apply to register marks and maintain registrations.

Before using a name, check:

federal trademarks through USPTO,
California business entity records,
county FBN records,
domain availability,
social media handles,
common law usage online,
similar names in your industry.

This is especially important if you plan to sell across state lines, build a national brand, franchise, raise investment or spend heavily on marketing.

6.Reserve the Name If You Are Not Ready to File

California allows name reservations for corporations, LLCs and limited partnerships. The California Secretary of State says a name can be reserved for 60 days, and name reservations can be submitted online through bizfile Online.

A name reservation can be useful if:

you are waiting for documents,
you are preparing investor paperwork,
partners have not signed final agreements,
you need time to set up a registered agent,
you are not ready to form the entity immediately.

However, a name reservation does not start the business, create an LLC, issue a licence or protect a trademark. It only temporarily holds the name for filing purposes.

7.Register an LLC Name in California

To register an LLC name in California, you usually file Articles of Organization with the California Secretary of State.

The LLC name must include an LLC identifier such as “Limited Liability Company,” “LLC” or “L.L.C.”

California Secretary of State name guidance also says an LLC name may not include words such as bank, trust, trustee, incorporated, inc., corporation or corp., and may not suggest insurance activity unless permitted.

The LLC filing registers the legal entity name. After that, the business may still need:

Statement of Information filing,
California Franchise Tax Board obligations,
local business licence,
seller’s permit if selling taxable goods,
industry permits,
county FBN filing if using another public trade name.

For cost planning, see: how much does it cost to start an LLC.

8.Register a Corporation Name in California

To register a corporation name in California, you usually file Articles of Incorporation with the California Secretary of State.

California name regulations say a proposed corporate name must be distinguishable in the records from existing corporate names and must not be likely to mislead the public.

A corporation may also need:

bylaws,
initial directors,
shares or stock structure,
Statement of Information,
federal EIN,
California tax registration,
business licence,
permits based on activity,
trademark checks for the brand name.

Corporation names and LLC names are reviewed under state rules, but approval by the Secretary of State does not mean the name is safe from trademark disputes.

9.Register a Fictitious Business Name in California

A Fictitious Business Name is used when a person or business operates under a name that is not the exact legal name of the owner or entity.

Common examples:

a sole proprietor named John Rivera operating as “Rivera Digital Studio,”
a partnership operating as “Sunset Coffee Partners,”
an LLC named “BRK Holdings LLC” operating as “Bay Road Kitchen.”

In California, FBN statements are generally filed with the county clerk or county clerk-recorder where the principal place of business is located. Some counties also allow online filing or online pre-application.

California Business and Professions Code guidance commonly requires a person regularly transacting business for profit under a fictitious business name to file a statement within 40 days after starting to transact business under that name.

10.Publish the Fictitious Business Name Notice

After filing an FBN statement, California generally requires publication in an approved newspaper.

County examples such as Los Angeles County, Santa Clara County, San Diego County, San Bernardino County and Riverside County state that publication must appear once a week for four consecutive weeks, usually starting within 45 days of filing.

Publication rules are important because missing the publication deadline may affect the validity of the filing.

The newspaper usually files proof of publication with the county, but business owners should confirm this with the newspaper and county clerk.

11.Renew or Refile When Required

Fictitious Business Name statements generally remain effective for five years, unless they expire earlier because of a change in the facts stated in the filing. Some county guidance confirms that FBN statements remain in effect for five years from the filing date.

You may need to renew or refile if:

the five-year period is ending,
the business address changes,
ownership changes,
the business entity changes,
the name changes,
the filing information is no longer accurate.
Do not rely only on memory. Add renewal dates to a compliance calendar.

For internal organisation, see: keep your business organized.

12.Register for Taxes, Permits and Local Licences

Registering a business name does not complete the full California business setup process.

Depending on your activity and location, you may still need:

EIN from the IRS,
California tax registration,
seller’s permit,
local business licence,
zoning approval,
health permit,
professional licence,
industry-specific permit.

The California Office of the Small Business Advocate says CalGOLD helps businesses identify local, state and federal permit information, including resources, application forms and agency contact information.

For local licensing, see: how to get a business license in California.

California Business Name Registration by Business Type

Business Type	Where Name Is Registered	Common Extra Steps
Sole proprietorship using owner’s legal name	Usually no state entity name filing	Local licence, tax registration if applicable
Sole proprietorship using trade name	County FBN filing	Publication, local licence, tax registration
General partnership using trade name	County FBN filing	Publication, partnership agreement, tax registration
LLC	California Secretary of State	EIN, Statement of Information, FTB/tax obligations, local licence
Corporation	California Secretary of State	EIN, Statement of Information, tax obligations, local licence
Existing LLC using another public brand name	Secretary of State for legal name, county FBN for trade name	Publication and renewal
Online business	Depends on structure and name used	Domain, seller’s permit, local licence, FBN if needed

California Business Name Search Checklist

Before you file, check:

California Secretary of State business search,
county FBN records,
USPTO trademark search,
California state trademark records where relevant,
Google search results,
domain name availability,
social media handles,
industry directories,
competitor names,
spelling variations,
similar names in the same niche.

California Business Name Restrictions

California name rules depend on the entity type.

For LLCs, the name generally must include an LLC identifier and must not include certain words that imply another entity type or regulated activity.

California Secretary of State guidance says LLC names may not include terms such as “bank,” “trust,” “trustee,” “incorporated,” “inc.,” “corporation” or “corp.,” and may not include words suggesting the LLC is an insurance company or assumes insurance risks.

For corporations, the proposed name must be distinguishable from existing corporate names on Secretary of State records and must not be likely to mislead the public.

Avoid words that could imply:

banking,
insurance,
government agency status,
professional licensing you do not have,
nonprofit status if you are not a nonprofit,
medical, legal or financial services without proper authorisation.

Does Registering a California Business Name Protect Your Brand?

Registering a California business name helps identify your business in state or county records, but it does not provide complete brand protection.

A business name filing may not stop another business from using a similar name in another state, another industry or under prior trademark rights. A federal trademark can offer broader protection if your mark qualifies and is approved.

The USPTO trademark system is separate from California business registration. Before applying for a trademark, review whether your brand name is distinctive, whether similar marks already exist and what goods or services the mark will cover.

Should You Register a Trademark?

You may want to consider trademark registration if:

the brand will be used outside California,
you sell online to customers in several states,
you are building a long-term brand,
you plan to franchise or license the name,
you are investing heavily in advertising,
your name is central to your product or service identity.

Trademark registration is not required for every small local business, but it can be valuable when brand identity matters.

Common Mistakes When Registering a Business Name in California

Mistake 1: Thinking a DBA Creates an LLC

A DBA or FBN does not create a legal entity. It only registers a business name. A sole proprietor with a DBA is still a sole proprietor unless they form an LLC, corporation or another entity.

Mistake 2: Forgetting County FBN Publication

Many California FBN filings require newspaper publication. Filing the form but missing publication can create compliance problems.

Mistake 3: Ignoring Trademarks

A name may be available with the California Secretary of State but still conflict with a federal trademark. Search trademarks before investing in branding.

Mistake 4: Registering the Domain Only

Buying a domain name does not register a business name with California and does not create trademark rights.

Mistake 5: Using Restricted Words

Words related to banking, insurance, professional licensing or government authority can trigger rejection or extra approvals.

Mistake 6: Not Checking Local Business Licence Rules

Registering a name is not the same as getting permission to operate. California businesses often need city or county licences and permits.

Mistake 7: Missing Renewal Dates

FBNs generally expire after five years. LLCs and corporations also have ongoing state filings and tax responsibilities.

Mistake 8: Choosing a Name That Limits Growth

A name that is too narrow may restrict future services, locations or product expansion.

Example: How a New California Business Might Register a Name?

Imagine a Los Angeles freelancer named Sofia Martinez wants to start a design business called “Pacific Studio Creative.”

Here is the likely path:

Sofia checks the California Secretary of State business search.
She checks Los Angeles County FBN records.
She searches USPTO trademarks.
She checks the domain and social handles.
If she stays a sole proprietor, she files an FBN with the county.
She publishes the FBN notice in an approved newspaper.
She applies for any required local business licence.
She registers for taxes if required.
She tracks the FBN renewal date.

If Sofia instead forms “Pacific Studio Creative LLC,” she would register the LLC with the California Secretary of State and may still need a county FBN if she uses a different public trade name.

Business Name Registration Checklist

Before you submit any filing, prepare:

preferred business name,
two or three backup names,
business structure,
owner or entity information,
business address,
mailing address,
registered agent details if forming an entity,
county of principal business location,
business description,
NAICS or industry category if requested,
EIN if already obtained,
domain name choice,
trademark search notes,
local licence requirements,
publication plan for FBN filing.

What to Do After Registering Your Business Name?

After registering your California business name, the next steps may include:

Apply for an EIN through the IRS if needed.
Register for California tax accounts.
Apply for a local business licence.

Apply for seller’s permit if selling taxable goods.
Open a business bank account.
Set up bookkeeping.
Protect your brand with trademark review.

Final Thoughts

Registering a business name in California is more than choosing a name you like.

You need to match the name to your business structure, check state and county records, understand whether you need an FBN, avoid misleading or restricted words, consider trademark risk and complete any local licensing steps.

The most important distinction is this: an LLC or corporation name is registered with the California Secretary of State, while a DBA or fictitious business name is usually filed with the county.

Neither one automatically replaces a business licence, tax registration or trademark search.

Start with official databases, keep records of your searches and filings, and build your brand on a name that is legally usable, clear to customers and flexible enough for future growth.

FAQ: Registering a Business Name in California

Do I need to register my business name in California?

Yes, if you are forming an LLC, corporation or limited partnership, your legal name is registered with the California Secretary of State.

If you are a sole proprietor or partnership using a name other than the owner’s legal name, you usually need a county Fictitious Business Name filing.

Is a fictitious business name the same as a DBA in California?

Yes. In California, a DBA is commonly called a Fictitious Business Name or FBN. It allows a person or entity to conduct business under a name different from the legal name.

Where do I register a DBA in California?

You usually register a DBA/FBN with the county clerk or county clerk-recorder where your principal place of business is located.

Can I register a California business name online?

Many Secretary of State business entity filings can be completed online through bizfile Online. Some counties also offer online FBN filing or pre-application, but county systems vary.

How long does a California name reservation last?

A California business entity name reservation lasts 60 days. It temporarily holds the name but does not form the business or provide trademark protection.

Does a California FBN expire?

Yes. FBN statements generally remain effective for five years unless they expire earlier due to changes in the filing information.

Do I need to publish my California DBA?

Usually yes. After filing an FBN, California county guidance commonly requires publication in an approved newspaper once a week for four consecutive weeks, usually within 45 days of filing.

Does registering a business name give trademark protection?

Not fully. Entity registration and FBN filing are different from trademark registration. For broader brand protection, search USPTO records and consider trademark registration if appropriate.

Can two California businesses have similar names?

Possibly, depending on entity type, county, industry, trademark rights and whether the name is distinguishable or misleading. Similar names can still create branding or legal risk.

Do I need a business licence after registering a business name?

Often yes. Registering a name does not replace local business licence, permit, zoning, tax or seller’s permit requirements.

Can I change my business name later?

Yes, but the process depends on the structure. An LLC or corporation usually files amendments with the Secretary of State.

A sole proprietor or partnership may need to file a new or amended FBN. You may also need to update IRS, tax, banking, licence and domain records.

For IRS-related changes, see: how to change business name with IRS.

Editorial note: This guide is for general business information only. California business name rules can vary depending on whether you are forming an LLC, corporation, partnership, sole proprietorship or filing a fictitious business name.

Always check official state, county and federal sources before filing.
