California lesson 1 of 6
Name your California LLC
California will reject your Articles of Organization if the name clashes with a name already on the register or breaks the naming rules, and a rejection costs you the whole processing queue again. Five minutes of checking here saves a fortnight.
What the name must contain
A California LLC name has to end with wording that tells the public it is a limited liability company. The Secretary of State accepts Limited Liability Company, or the abbreviations LLC or L.L.C. The words Limited and Company may themselves be shortened to Ltd and Co.
- Acceptable: Nova Ventures LLC, Nova Ventures L.L.C., Nova Ventures Limited Liability Company
- Not acceptable: a name that suggests a different structure, such as Inc, Corporation or Incorporated
- Not acceptable: a name that would mislead the public about what the business does
Restricted and prohibited words
Some words cannot be used at all in an LLC name, and others need approval from the regulator that oversees that field. Bank, trust, trustee, incorporated, insurer and similar terms are the common blockers. California also does not allow an LLC to be formed to provide a professional service that requires a state licence, which is why doctors, lawyers, architects and accountants in California use a professional corporation rather than an LLC.
If your business needs a California professional licence to operate, check before you file. The LLC route is closed for most licensed professions in this state.
Check the name is free
Search the Secretary of State business search first. The comparison is not just exact matches: California will refuse a name that is likely to mislead the public because it is too close to an existing one. Test a couple of alternatives so a rejection does not stall you.
If you are not ready to file yet, you can hold a name for 60 days by filing a Name Reservation Request for $10. It is optional and most people skip it.
🇺🇸 Check United States company name availability
Search the official United States state registry before you file. Opens the government portal in a new tab.
Tip: also confirm the .com domain and matching social handles are free before you commit.
Key takeaways
- End the name with LLC, L.L.C. or Limited Liability Company.
- Licensed professions generally cannot use a California LLC.
- A $10 reservation holds a name for 60 days if you are not filing straight away.
Frequently asked questions
Do I need a separate DBA in California?
Only if you trade under a name different from the LLC's registered name. That is filed as a fictitious business name statement with the county clerk where your business is located, not with the Secretary of State.
Can two California businesses share a name?
Not on the LLC register. A trademark is a separate question, and clearing your name with the USPTO is worth doing before you invest in branding.
