California LLC Name Search

How to search for LLC names in California

Searching for an available LLC name in California is a required first step before submitting your Articles of Organization to the California Secretary of State. The Business Search database on the Secretary of State's website shows all active and inactive business entities registered in California, including LLCs, corporations, and limited partnerships. Running a search lets you confirm whether your proposed name is distinguishable from existing registrations. Keep in mind that a name appearing available in the database does not guarantee approval — the Secretary of State makes the final determination at filing time. Additionally, state registration does not protect your name at the federal trademark level, so a separate trademark search is strongly recommended before investing in branding or marketing materials.

Step-by-step: using the California Secretary of State name search

1. 1. Go to the California Secretary of State Business Search portal at https://bizfileonline.sos.ca.gov/search/business.
2. 2. Select 'Business Name' as your search type from the search options available on the page.
3. 3. Enter your proposed LLC name or a keyword variation into the search field and click the Search button.
4. 4. Review the results list carefully, looking for names that are identical or confusingly similar to your proposed name, including alternate spellings, abbreviations, and plural forms.
5. 5. If no conflicting names appear, note that the name may be available, but confirm by also checking recently dissolved entities and considering filing a Name Reservation (Form NP-1) to hold the name for up to 60 days while you prepare your Articles of Organization.

California LLC naming rules

• The LLC name must include the words 'Limited Liability Company', the abbreviation 'LLC', or 'L.L.C.' as the last words of the name.
• The name must be distinguishable from the name of any existing California business entity or reserved name on record with the Secretary of State.
• The name cannot contain words that imply the LLC is a government agency, such as 'State', 'Federal', 'United States', 'FBI', or similar terms.
• The name cannot include words suggesting an affiliation with financial institutions — such as 'Bank', 'Trust', 'Trustee', or 'Credit Union' — without prior approval from the California Department of Financial Protection and Innovation.
• Words implying the LLC provides professional licensed services — such as 'Attorney', 'Doctor', 'Architect', or 'Engineer' — are restricted and may require a professional license or regulatory approval.
• The name cannot include terms related to insurance — such as 'Insurance', 'Insurer', 'Assurance', or 'Surety' — without prior approval from the California Department of Insurance.
• The name must not be obscene, profane, or likely to mislead the public about the nature or purpose of the business.
• California does not allow the use of 'Corporation', 'Corp.', 'Incorporated', or 'Inc.' in an LLC name, as those designators are reserved for corporations.

Restricted words in California LLC names

• Insurance / Insurer / Assurance / Surety — requires approval from the California Department of Insurance

How to reserve an LLC name in California

California allows you to reserve an LLC name before filing by submitting Form NP-1 (Name Reservation Request) to the Secretary of State, along with a $10 filing fee. The reservation holds the name exclusively for 60 days. You can submit the form by mail or in person at a Secretary of State office. Name reservations cannot be renewed or extended, so you must file your Articles of Organization within the 60-day window or reapply with a new reservation request.

Tips for choosing an LLC name that passes in California

• Search for your exact proposed name and then run additional searches using common misspellings, abbreviations, and keyword variations — the Secretary of State applies a 'distinguishable' standard that may catch names you would not expect to conflict.
• After checking the California database, search the USPTO Trademark Electronic Search System (TESS) at tmsearch.uspto.gov to confirm the name is not already federally trademarked, which could expose you to infringement liability regardless of state approval.
• Check domain name availability for your LLC name simultaneously using a registrar such as Namecheap or GoDaddy — securing a matching .com domain early protects your online presence.
• Avoid including geographic terms like 'California', 'Northern California', or specific city names in your LLC name unless your business is permanently local, as they can limit your brand's flexibility if you expand to other states.
• Consider how your name will appear in abbreviated form, in email addresses, and on social media handles before committing — short, distinctive names tend to perform better and are easier to protect.
• File a Name Reservation (Form NP-1) as soon as you settle on a name to lock it in for 60 days while you complete your Articles of Organization and obtain any required licenses or approvals.
