California LLC Name Rules

Name Distinguishability Requirement

Your LLC name must be distinguishable from all other business names already on file with the California Secretary of State. This means your name cannot be identical to or confusingly similar to any existing registered business entity in California's records. The Secretary of State applies a strict standard: your name must be clearly different when reviewed against the official business database.

You can search existing business names free of charge using the California Secretary of State's online business search tool at https://bizfileonline.sos.ca.gov/search/business. This database includes all active corporations, LLCs, partnerships, and other registered entities. Before submitting your Articles of Organization, conduct a thorough search to verify your chosen name is available and distinguishable.

The distinguishability requirement applies even if another business operates under a similar name in a different state or uses the name for a different purpose. California's standard is based solely on what appears in the Secretary of State's official records.

When searching, use multiple variations of your intended name. Search for the exact name, common abbreviations, and phonetically similar names. For example, if you plan to use "Green Valley Consulting LLC," also search "Green Valley," "Greenvalley," and "GreenValley" to identify any potentially confusing existing names.

Name Reservation: Process and Duration

You can reserve your LLC name for 60 days before filing your Articles of Organization. This reservation protects your chosen name while you prepare your formation documents and conduct due diligence. To reserve a name, you submit a Name Reservation Request directly to the California Secretary of State.

The name reservation fee is $10.00. You can file the reservation online through the Secretary of State's BizFileonline portal at https://bizfileonline.sos.ca.gov/. The 60-day reservation period begins on the date the Secretary of State approves your request, giving you a two-month window to complete your LLC formation.

If you do not file your Articles of Organization within the 60-day reservation period, the reservation expires and your name becomes available for other businesses to use. You can renew the reservation by submitting another request and paying an additional $10.00 fee, but you cannot extend the existing reservation beyond its expiration date.

Conducting a Name Search

Before reserving or filing your LLC name, you must search the California Secretary of State's business database to confirm availability. The free online search tool at https://bizfileonline.sos.ca.gov/search/business allows you to search by business name, file number, or agent name.

The search results display all registered entities with matching or similar names, their file numbers, and registration status. If you find an existing business with an identical or confusingly similar name, you must choose a different name for your LLC. The Secretary of State will reject any filing that violates the distinguishability requirement.

Searching multiple name variations prevents rejection and wasted filing fees. The search is instantaneous and accessible 24/7, making it easy to verify availability before you commit to a name choice.

DBA (Doing Business As) Requirements and Filing

If your LLC operates under a name different from its registered legal name, you must file a Doing Business As (DBA) statement, also called a fictitious business name statement. This requirement applies even if your LLC name includes the required "LLC" designator but you want to conduct business under an alternate name.

For example, if your LLC is legally named "Tech Solutions LLC" but you want to operate as "Tech Innovations," you must file a DBA statement. The DBA filing notifies the public of the connection between your legal LLC name and your operating name.

DBA filings are submitted to your county clerk's office, not the California Secretary of State. The filing fee is $26.00 per county where you conduct business. If you operate in multiple counties, you must file a separate DBA statement in each county.

DBA statements must be renewed every five years. The renewal deadline is five years from the date of original filing. Failure to renew results in expiration of your DBA registration, though your LLC itself remains active. Contact your county clerk's office for specific renewal deadlines and procedures.

Filing Your LLC Name with the Secretary of State

Once you have confirmed your name is available and distinguishable, you file it as part of your Articles of Organization with the California Secretary of State. Your LLC name appears on the cover page of your Articles and becomes your official registered name in California's business records.

You can file your Articles of Organization online through BizFileonline at https://bizfileonline.sos.ca.gov/ or by mail. Online filing is faster and provides immediate confirmation of receipt. The filing fee for Articles of Organization is $70.00 (as of 2026).

Your LLC name becomes effective on the date the Secretary of State approves your Articles of Organization. From that date forward, your LLC is legally registered under that name in California, and you have exclusive rights to use that name in California's business records.

Name Changes After Formation

If you want to change your LLC name after formation, you must file an Amendment to Articles of Organization with the California Secretary of State. The amendment must state your current registered name and your new desired name. The new name must still comply with all naming requirements—it must include the required designator, avoid restricted words without authorization, and be distinguishable from existing business names.

Before filing your amendment, search the Secretary of State's business database at https://bizfileonline.sos.ca.gov/search/business to confirm your desired new name is available. You can also reserve the new name for 60 days ($10.00 fee) while you prepare your amendment documentation.

The amendment filing fee is $70.00. You can file amendments online through BizFileonline or by mail. The name change becomes effective on the date the Secretary of State approves your amendment.

If you file a name change, you may also need to update your DBA statement if you operate under a fictitious name. Contact your county clerk's office to determine whether a new DBA filing is required.

Contact Information for Name-Related Questions

For questions about LLC naming requirements, name availability, or the name reservation process, contact the California Secretary of State directly:

The Secretary of State's office can confirm whether a specific name is available, explain the distinguishability standard, and provide guidance on restricted words. You can also submit questions through the Secretary of State's website contact form.

For questions about DBA filings, contact your county clerk's office directly. Each California county maintains its own DBA filing system and can answer questions about local requirements and fees.

FAQ: California LLC Naming Rules

Q: Can I use "Inc." or "Corporation" in my LLC name?

A: No. Under California Corporations Code § 17701.08, you cannot use "Inc.," "Incorporated," or "Corporation" in an LLC name under any circumstances. These designators are reserved exclusively for corporations. Your LLC name must end with "LLC," "L.L.C.," or "Limited Liability Company."

Q: What happens if someone else registers my desired LLC name before I file?

A: The California Secretary of State will reject your Articles of Organization if your chosen name is not distinguishable from an existing registered business. You must choose a different name. This is why searching the Secretary of State's database at https://bizfileonline.sos.ca.gov/search/business before filing is critical. A 60-day name reservation ($10.00) can protect your chosen name while you prepare your formation documents.

Q: Do I need to file a DBA if my LLC name already includes "LLC"?

A: Only if you operate under a name different from your registered LLC name. For example, if your LLC is legally named "Smith Consulting LLC" but you want to do business as "Smith's Consulting Services," you must file a DBA with your county clerk ($26.00 fee). The DBA requirement applies to any assumed business name, regardless of your LLC's official designation.

Q: Can I use "Bank" or "Insurance" in my LLC name?

A: Only with special authorization. California Corporations Code § 17701.08 prohibits these words without prior approval from the California Department of Financial Protection and Innovation (for "Bank") or the California Department of Insurance (for "Insurance"). You must obtain written consent from the appropriate agency and attach it to your Articles of Organization before the Secretary of State will approve your filing.

Q: How long does a name reservation last?

A: A California LLC name reservation lasts exactly 60 days from the date the Secretary of State approves your request. If you don't file your Articles of Organization within this period, the reservation expires and your name becomes available for others to use. You can renew by submitting another $10.00 reservation request, but you cannot extend an existing reservation beyond its expiration date.

Q: What if my search finds a similar but not identical name?

A: The California Secretary of State applies a strict distinguishability standard. If an existing business name is confusingly similar to your proposed name, the Secretary of State may reject your filing. If you're uncertain whether your name is sufficiently distinguishable, contact the Secretary of State at (916) 657-5448 before filing. They can clarify whether your proposed name meets California's distinguishability requirement.

Q: Do I need to renew my DBA registration?

A: Yes. California requires DBA registrations to be renewed every five years from the original filing date. If you don't renew before the deadline, your DBA registration expires, though your LLC itself remains active. Contact your county clerk's office for specific renewal deadlines and procedures in your county.

Q: Can I change my LLC name after formation?

A: Yes. You can change your LLC name by filing an Amendment to Articles of Organization with the California Secretary of State ($70.00 fee). Your new name must still comply with all California naming requirements: it must include the required designator, avoid restricted words without authorization, and be distinguishable from existing business names. File online at https://bizfileonline.sos.ca.gov/ or by mail.
