To check whether a business name is available in California, run a SOS business name search at bizfileonline.sos.ca.gov, the Secretary of State’s free online portal that lets you look up every registered entity in the state. A search that returns no matches is a good sign, but it isn’t a guarantee: the Secretary of State applies its own review when you file formation documents and can still reject a name that looked clear in the database.
How to Run the Search
Open the portal and choose the business search tab. No account is needed. Select “Entity Name” as your search type, type in your proposed name, and hit search.
A few small habits make the results more useful. Drop entity suffixes like “LLC,” “Inc.,” or “Corp.” from the query, since they clutter results without flagging real conflicts. Leave out punctuation; the database doesn’t handle it consistently. If your name contains common words, search only the distinctive part. For “Redwood Coast Consulting LLC,” search “Redwood Coast” and see what comes up.
Run several variations. Swap abbreviations for full words and the other way around, try alternate spellings, and test each distinctive word on its own. People who search only the exact string they want tend to get blindsided when the Secretary of State flags something close during the filing review.
Reading Your Results
“No results found” means no entity with that exact name string is currently on file. It doesn’t guarantee acceptance. The Secretary of State can still reject the name during manual review if a phonetically similar or visually confusing name exists under a different spelling.
When results appear, look at two columns: the entity name and its status. “Active” means currently registered and off-limits. “Dissolved,” “Cancelled,” or “Surrendered” means the business is no longer operating, but California still treats those names as part of its records for distinguishability purposes. A closed business doesn’t free up its name.
Watch for near-matches as closely as exact ones. If you want “Pacific Trail Designs” and “Pacific Trails Design Inc.” is active, expect trouble. The Secretary of State judges the overall impression a name creates, not whether every character matches.
What Makes a Name Distinguishable in California
California law requires every business entity name to be distinguishable from names already on file. Corporations Code Section 201 sets the standard for corporations, and Section 17701.08 does the same for LLCs. Both statutes say the Secretary of State will reject any name it determines is “likely to mislead the public.”1California Legislative Information. California Corporations Code – Section 2012California Legislative Information. California Corporations Code 17701.08
“Distinguishable” takes more than a trivial change. Swapping “and” for “&,” adding or dropping “the,” or shuffling punctuation won’t do it. The name needs a genuinely distinctive element that keeps it from being confused with an existing one. Phonetic similarity counts too; if two names sound alike spoken aloud, a different spelling won’t save you.
Your proposed name is compared against several categories of existing records: every domestic corporation and LLC on file, every foreign corporation or LLC authorized to do business in California, every name currently under reservation, and alternate names adopted by foreign corporations operating here. That’s a wide net, which is why running thorough searches up front matters.
Restricted Words That Need Advance Approval
Some words require approval before the Secretary of State will accept them in a business name. “Bank” and “Trust” are the most common triggers. If your corporation isn’t actually in the banking or trust business, you need a Certificate of Approval from the Department of Financial Protection and Innovation before filing. For fictitious business names containing those words, the DFPI issues a Letter of No-Objection instead. Skip this step and the filing gets rejected.3Department of Financial Protection and Innovation. Corporate Names and Information
California also prohibits names that imply a purpose the business doesn’t actually serve. A consulting firm can’t adopt a name suggesting it’s a government agency or a licensed financial institution. Misleading names get rejected even when nothing identical appears on file.
Reserving a Name for 60 Days
If the name looks available but you aren’t ready to file formation documents yet, you can reserve it for 60 days. The fee is $10, payable by check if you mail the form or online through bizfile. The reservation blocks anyone else from registering the name while you finish your paperwork.4California Secretary of State. Name Reservation Request Form
One catch catches people off guard: you cannot reserve the same name for two consecutive 60-day periods. The statute prohibits back-to-back reservations by the same person, and the prohibition extends to names similar enough to fall within the distinguishability rules. You can’t tweak the name slightly and re-reserve it.5California Legislative Information. California Corporations Code 17701.09
A reservation also doesn’t guarantee the name will survive filing. At the reservation stage the Secretary of State only confirms the name appears available in the database. Restricted-word approvals, entity-type naming requirements, and other legal standards are evaluated only when you submit the actual formation documents.6California Secretary of State.

Locking the Name In Through Formation
A name isn’t truly yours until the Secretary of State accepts your Articles of Incorporation (for a corporation) or Articles of Organization (for an LLC). That filing is where the state conducts its full review. Even with a clean search and a paid reservation, the state can still reject the name at this stage if it doesn’t meet every legal requirement.4California Secretary of State.

The Secretary of State’s own guidance says it plainly: don’t order stationery, signs, or make financial commitments tied to a proposed name until the formation documents have been filed and accepted.6California Secretary of State. Name Reservations
Search Federal Trademarks Separately
The California business entity search only tells you whether a name is registered as a business entity with the state. It tells you nothing about federal trademark rights. Someone in another state could hold a registered trademark on the exact name you want, and that trademark gives them the legal right to stop you from using it anywhere in the country, no matter what California’s database shows.
Before you commit, search the U.S. Patent and Trademark Office database at tmsearch.uspto.gov. The tool is free and covers both registered marks and pending applications. If you find a match in the same industry or a related one, pick a different name. A trademark infringement claim can lead to a court order forcing you to rebrand, plus damages. That is a far more expensive problem than choosing a different name at the start.7United States Patent and Trademark Office. Search Our Trademark Database
State registration and federal trademark protection serve different purposes. Registering an LLC name in California gives you the right to use that name as your legal entity name in the state. It does not give you exclusive commercial rights to the name as a brand. If brand protection matters to the business, pursue a federal trademark registration separately.
A Note on DBAs
If you plan to operate under a name different from your entity’s legal name (for example, “JKM Holdings LLC” doing business as “Coastal Candle Co.”), you file a fictitious business name statement with the county clerk where your principal place of business is located. That is a separate process from the Secretary of State search and filing, and it is governed by California Business and Professions Code Section 17900.8California Legislative Information. California Business and Professions Code 17900 A DBA does not give you exclusive rights to the name and does not replace entity formation with the state. Checking name availability through the Secretary of State is a separate step from any DBA filing you may also need.
