California Rules on Naming Your corporation or LLC

Once you’ve checked to see if your California business name is available, you’ll need to confirm it follows certain naming rules.

Your California business name should not be confusable with or similar to another business in CA.

Normally, you cannot imply connection with a California state entity or that you will be carrying out activities your CA business is not legally able to provide.

If your California business is an LLC, it must contain “Limited Liability Company” or an abbreviation. If it’s a corporation, it must contain a word like “Incorporated,” “Corporation” or something similar.
