How to Check If Your California LLC Name Is Available on bizfile Online

You can check whether a California LLC name is available for free on bizfile Online, the California Secretary of State online filing and search system. Enter your proposed name, review the results for exact matches and close matches, and confirm that the name is distinguishable from other business names already on record. If the name passes that check and meets California naming rules, you can reserve it for 60 days for $10 or move straight to filing Form LLC-1 for $70.

What bizfile Online Is

bizfile Online is the California Secretary of State online portal for business filings and business searches. For a founder, its most useful early feature is the business search, which shows names already registered in California. That search is free, and it is the right first step before you print business cards, buy a domain, or sign a lease in a new business name.

Step by Step: Run the Free Name Search

Start by writing down three to five name options, ranked in order of preference. Then use the business search on bizfile Online to enter each option exactly as you would write it in your formation filing, including the LLC ending. Search the full name first, then search the distinctive words without the ending, because a similar core name can cause a problem even when the ending is different.

Many founders begin with a dedicated guide to the california llc name search before they run their own search, because it explains the distinguishable rule in plain language and shows what kinds of differences the state will and will not accept. Keep a short note of every name you searched and what you found.

Read each result carefully. Look at the entity type, the status, and the full legal name, not just the first word. If you see a close match in the same industry or the same part of California, assume the risk is higher and move to your next option rather than arguing that customers would tell the difference.

The Distinguishable Rule in Plain Language

California requires an LLC name to be distinguishable on the records of the Secretary of State from the names of other entities already registered in the state. In practice, that means your name cannot be the same as an existing name, and it cannot be so similar that it would be confused with an existing name. Changing only the punctuation, changing only the capitalization, adding or removing a space, or swapping a word like Company for Co. is generally not enough on its own.

A stronger difference comes from the distinctive part of the name. A unique invented word, a distinctive combination of words, or a clearly different core word is much more likely to pass than a generic word plus a city name or a common industry word.

The LLC Ending and Words You Cannot Use

Every California LLC name must include one of three endings: LLC, L.L.C., or Limited Liability Company. The ending tells the public that the business is a limited liability company, and it is part of the legal name, not an optional label you can add or drop when it is convenient.

Do not add an ending that belongs to another type of entity. Do not use Inc., Incorporated, Corporation, or Corp. in an LLC name, because those endings signal a corporation. Likewise, do not use the words bank or trust, or words that suggest your business is a bank, a trust company, or an insurer, unless you have the approvals California requires for that kind of business.

Professionals, Reservation, Filing, and Annual Tax

Licensed professionals face a special limit in California. In general, professionals such as doctors, lawyers, accountants, and architects cannot form a regular LLC for their licensed practice, and California instead requires a professional corporation or another permitted structure for many licensed professions.

If you find a name you like but you are not ready to file yet, you can reserve it with the Secretary of State for $10. The reservation holds the name for 60 days, which gives you time to finish your operating agreement, line up a registered agent, and prepare your filing. To form the LLC, you file Articles of Organization, Form LLC-1, for $70. After formation, California LLCs owe an $800 annual tax to the Franchise Tax Board, with limited exceptions for the first year for some new LLCs under current law.

Trademarks, DBA Rules, and What to Do If Your Name Is Taken

Approval by the Secretary of State does not mean your name is safe as a trademark. State approval only means the name is distinguishable on state records. A trademark owner in another state, or a federal trademark owner, could still object if your name would confuse customers about the source of goods or services.

Your LLC legal name is the name on Form LLC-1. If you want to operate under a different name, California generally requires you to file a fictitious business name statement, often called a DBA, with the county where your principal place of business is located, and to publish it as county rules require. If your first choice is taken, do not force it through with a trivial change. Add a distinctive word or invent a new core word, check the new option again, and file promptly, because names are claimed on a first come, first served basis.

Conclusion

Checking a California LLC name on bizfile Online is free, fast, and essential, but it is only the first step. Confirm that the name is distinguishable, that it includes LLC, L.L.C., or Limited Liability Company, and that it avoids restricted words and corporation endings. Reserve the name for $10 for 60 days if you need time, then file Form LLC-1 for $70 and plan for the $800 annual tax. Check trademarks separately, register a DBA if you will use another operating name, and confirm the right entity type if you are a licensed professional. A careful name check now saves rejection, rebranding, and delay later.
