How to Register a Business Name in California: Step-by-Step Guide

Coming up with the perfect name for your business is a big moment—it feels real. But before you start building your website, printing marketing materials, or setting up social media, there's a critical step that many first-time founders overlook: registering your business name in California.

Whether you're starting an LLC, running a sole proprietorship, or filing a DBA, registering your business name properly helps you avoid legal conflicts, protect your brand, and start strong. This guide walks you through the full process: checking name availability, reserving a name, registering it with the Secretary of State or county, filing a fictitious business name (FBN), and adding trademark protection—step by step, with current fees as of 2026.

1. Checking Business Name Availability in California

Before you fall in love with your business name, make sure it's available. California requires entity names to be distinguishable from existing businesses on file with the Secretary of State.

How to Run a California Business Name Search:

✔️ Search the California Secretary of State's bizfile Online database—this covers LLCs, corporations, and limited partnerships already registered in the state.
✔️ Run a trademark search on the USPTO website to make sure your name isn't protected at the federal level.
✔️ If you'll operate under a DBA, check your county clerk's fictitious business name index too—FBN filings live at the county level, not in the state database.
✔️ Double-check domain name and social handle availability if you plan to build an online presence.

📌 Tip: An online California LLC name search is preliminary, not a guarantee. The Secretary of State only confirms availability when it processes and accepts your actual filing.

2. Reserving a Business Name in California

Not quite ready to file your formation documents, but want to lock in your name? California lets you reserve a name for 60 days so no one else can claim it while you finish your setup.

What You Need to Know:

✔️ Submit a Name Reservation Request through bizfile Online—the Secretary of State recommends online filing for faster service.
✔️ Fee: $10 per reserved name (an extra $10 special handling fee applies only if you drop off a paper form in person).
✔️ The reservation cannot be renewed for consecutive 60-day periods. You can reserve the same name again, but there must be at least one day between reservation periods.
✔️ Reserving a name doesn't guarantee it meets every requirement for your entity type—names are fully reviewed when you file your formation documents.

📌 Tip: Don't treat the reservation as a long-term parking spot. If you're serious about the name, file your formation documents within the 60-day window.

3. Registering Your Business Name with the State

Once you're ready to make your business official, your name gets registered as part of forming your entity. Unlike some states, California does not require a separate name registration if you're forming a legal entity under that name—the formation filing is the registration.

Key Details:

✔️ LLC: File Articles of Organization (Form LLC-1) through bizfile Online. Filing fee: $70. Your LLC name is registered the moment the state accepts the filing. Full walkthrough in our California LLC formation guide.
✔️ Corporation: File Articles of Incorporation. Filing fee: $100 for a stock corporation. Not sure which structure fits? See our LLC vs. corporation comparison.
✔️ Sole proprietorship or general partnership: There's no state-level name registration. If you operate under anything other than your own surname, you file a Fictitious Business Name (FBN) at the county level (covered below).
✔️ Out-of-state businesses: If your company is registered elsewhere but wants to operate in California, you must register as a foreign entity with the Secretary of State before doing business in the state.

Two follow-up filings catch many new owners off guard. First, California LLCs and corporations must file an initial Statement of Information within 90 days of formation ($20 for LLCs, $25 for corporations). Second, registering your name doesn't register your tax accounts—you'll still need an EIN from the IRS (here's how to file Form SS-4) and, for LLCs and corporations, you'll owe California's $800 minimum franchise tax. Our California franchise tax guide covers the forms and deadlines.

📌 Tip: Budget for the whole stack, not just the name: formation fee + Statement of Information + $800 annual franchise tax. The name registration itself is the cheapest part.

4. Filing a DBA (Fictitious Business Name) in California

If you want to operate under a name that's different from your official business name, you'll need a DBA (Doing Business As)—officially called a Fictitious Business Name (FBN) in California. This is the most common filing for sole proprietors, and it's also how an LLC or corporation runs a second brand without forming a new entity.

A DBA doesn't create a separate legal entity, and it doesn't change your liability or tax status. Your legal name stays the one on file with the Secretary of State (or your personal name, for sole proprietors)—the FBN is simply an alternate, public-facing name your existing business operates under. California DBA filings are also non-exclusive: registering an FBN doesn't stop another business from using a similar name. For real name protection, you need the trademark layer in the next section.

How California DBA Filing Works:

✔️ Any business type—sole proprietors, partnerships, LLCs, and corporations—can file an FBN, and you can register multiple DBAs under one business.
✔️ File with the county clerk in the county of your principal place of business—not with the Secretary of State. California law expects the statement to be filed within 40 days of starting to transact business under the name.
✔️ Filing fees vary by county, typically $25–$60 for the first name. In Los Angeles County, for example, it's $26 for the first name plus $5 for each additional name or registrant.
✔️ Publication requirement: within 30 days of filing, you must publish the statement in an adjudicated newspaper in that county, once a week for four consecutive weeks, then file an affidavit of publication with the county clerk within 30 days after the last run.
✔️ An FBN statement expires after 5 years. Renew before expiration—if nothing has changed, most counties don't require re-publication on renewal.

📌 Tip: Newspapers handle FBN publication constantly, and many county clerk websites list approved papers. Ask the paper to file the affidavit of publication for you—most will.

5. Protecting Your Name with a Trademark

Registering your name with the state or county gives you the right to use it—but it doesn't stop a competitor in another state (or even another county) from trading on it. That's what trademarks are for, and you have two layers to choose from:

✔️ California state trademark: File with the Secretary of State's Trademark Unit. Fee: $70 per classification, valid for 5 years and renewable in the final 6 months for $30. Good protection if you only operate in California.
✔️ Federal trademark (USPTO): Nationwide protection. The base application fee is $350 per class as of 2026, with surcharges for incomplete or free-form applications. Worth it the moment you sell across state lines.

📌 Tip: A trademark protects the name as a brand; entity registration protects it as a legal identity. Growing businesses usually end up needing both.

6. Changing Your Business Name in California

Business evolving? Need a rebrand? You can change your official business name anytime, but it requires proper filing.

Steps to Update Your Name:

✔️ File a Certificate of Amendment with the California Secretary of State via bizfile Online. Fee: $30 for LLCs and corporations.
✔️ Update your records with the IRS, the California Franchise Tax Board, and the CDTFA if you have a seller's permit.
✔️ Notify your bank, vendors, insurers, and licensing agencies.
✔️ If the old name had an FBN attached, file an abandonment with the county and a new FBN statement for the new name.

📌 Tip: Don't forget the branding sweep—website, invoices, contracts, social profiles, and anywhere else the old name appears.
