California Business Entity Searches & Naming Your LLC

California Secretary of State Business Search

Once you've picked out a name for your business, you'll need to complete a California LLC search with the CA Secretary of State. The SOS has a helpful tool on their website that lets you search the registry of California LLCs and corporations to see if someone already has your desired business name.

If the name is already used according to the business entity search tool, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

California Naming Rules for LLCs

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet California Secretary of State naming rules. These do vary from state to state — we’ve got general naming rules below, as well as naming rules specific to LLC businesses formed in CA.

General Business Name Availability Rules

These rules typically apply to all LLCs, no matter what state they are formed in. You will need to pay attention to these rules, as they will influence the name you choose for your California LLC.

Your LLC Business Name Must Be Unique

The business name you have chosen cannot be used by any other LLC or corporation in the state of California. This is why you should check business name availability on the CA SOS website.

Your LLC Business Name Must Not Be Confusable With Another Business Name

It’s not enough for your CA LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in California. For example, you cannot use the following factors to say your name is different from the name of another business:

• Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., Ltd., LLC, etc.
• Definite articles like “A,” “And,” “An,” “&,” “The,” etc.
• The singular, plural or possessive forms of a word
• Abbreviations, punctuation, symbols, fonts, typefaces, etc.

Your LLC Business Name Must Contain Certain Words

All LLCs must have the words “Limited Liability Company,” “L.L.C.” or “LLC” in their name. These words should normally come at the end of the name.

Your LLC Business Name May Have Other General Restrictions

Most states will not allow you to form LLCs with names that:

• Are very similar to the name of a federal or CA agency or organization (e.g. FBI, FDA, California Tax Service Center, California Police, Treasury, etc.)
• Suggest affiliation with a federal or state agency or organization
• Use the term “Olympic” or any terms that are trademarks of the Olympic organization
• Imply a purpose that it would be illegal for your business to carry out

Specific LLC Naming Rules for California

In addition to the general rules listed above, the California Secretary of State has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your CA business appropriately.

• The business name may not include the words "corporation, corp, trustee, bank, trust, incorporated or inc."
• Your California business name cannot include any words suggesting you are an insurer or assume insurance risks.
• The business name cannot include “Agency,” “Commission,” “Department,” “Bureau,” “Division,” “Municipal” or “Board.”
• Although these are the main rules about naming your business in California, there are plenty more. You can find additional rules about naming your California business on the California Secretary of State website.

California LLC Fictitious Names

You might choose to do business under a different name from your legal LLC name. In California, doing business under a different name is known as a “Fictitious Name.” You might choose to use a different name from your CA formal LLC name for a variety of reasons.

For example, your LLC might be called California Leisure and Travel Holding Company LLC, and you have a chain called Hollywood Bus Tours. You should file a Fictitious Name to let the California Secretary of State know. In California, you do that through filing a form with the county administration that your business is located in. You can also have Incfile do it on your behalf through our Assumed Business Name service.

Register Your California LLC Business Name

Once you’ve searched for your California business name, checked availability, followed the naming rules and decided whether you need a fictitious name, you can register your CA LLC name. There are a couple of ways to do this.

1. If you don’t want to form your California LLC right now, you can reserve the business name with the California Secretary of State. You will need to complete a “Name Reservation Request” and file it with the CA SOS. You do not need to reserve a name if you are forming your business right away.
