Register a Fictitious Business Name in California

Registering a California fictitious business name, also known as a DBA, is easy!

Your California fictitious business name must be unique and must also meet California’s business name requirements.

Before you file, you will need to search county records to make sure your exact name isn’t already taken. We will provide contact information for county offices in Step 2. You will also need to consider any state naming rules.

Your California fictitious business name should NOT include:

  • Any business entity suffix, such as LLC, Incorporated, Corp, etc., unless the business is actually an LLC, corporation, etc.
  • Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your business.

For a complete list of naming rules in California, you can read California's Code of Regulations.

We recommend checking if your name is available as a web domain (URL). You might not plan on starting a business website today, but you may want to prevent others from acquiring your URL.

Step 2: Use Your California Fictitious Business Name

California fictitious business names are filed with the county where your principal place of business is located.

If your principal place of business is outside of the state of California, you must file with the Sacramento County Clerk. Nonprofits are not required to file a Fictitious Business Name Statement.

Filing a DBA With the County Clerk

DBA regulations are managed by the state of California which means the steps for getting a DBA are similar from county to county.

Step 3: Register Your California DBA

Within 30 days of registering your fictitious business name, the state of California requires that you publish a "fictitious business name statement" in a newspaper in the county where your principal place of business is. You must publish once a week for four weeks.

Publication requirements are explained in detail on the California Legislative website. The basic steps are:

  • The newspaper must be a general circulation publication that circulates in the county where you register your fictitious business name. You can find a list for LA County on the LA County website.
  • Contact the newspaper of your choice that circulates in your county and is on the list mentioned above. Request to publish a “fictitious business name statement” in the newspaper once a week for four weeks. 
  • If re-filing your fictitious business name is required (the original expired), you must publish a statement again.
  • Lastly, you must file an affidavit proving publication within 30 days of the completion of publication. In LA county, this can be completed by following the steps detailed on the LA County publication info page.

You should direct any questions about publication requirements to the county clerk’s office that you registered your fictitious business name with. You can find the complete list of county contact information on the California Department of Public Health's website.

After Filing Your California DBA

If filing a DBA marks the beginning of your business journey, then there are a few more steps that you should take before getting started:

  • Create your Business’s Website - Every business needs a website. Luckily, drag-and-drop builders like GoDaddy and Wix make the job quick and easy. Check out our Best Website Builder article to find the tool that’s best for you.
  • Get your Business Finances in Order - You’ll need to separate your business finances from your personal ones. This is accomplished by opening a business bank account. If your business has long lead times or other cash flow irregularities, you can also look into a business credit card.
  • Protect Your Business - While an LLC will help to protect your personal assets in the case of a lawsuit, your business’s assets also need protection. Having the right business insurance will ensure that you’re covered if the worst happens. Most businesses start with general liability insurance as their base coverage.

DBA California FAQ

You can have as many DBAs as you can afford to create and are able to keep track of. Each one comes with additional incremental expenses and paperwork, meaning more is not necessarily better.

DBAs aren’t required to have a separate EIN because DBAs aren’t a business entity. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you need one for your business, read our What is an EIN guide.

No. An LLC is a business entity, while a DBA is just a name for a business.

Sole proprietorships are often confused with DBAs, but they are not the same: a sole proprietorship is a business entity, therefore it can choose to become an LLC.

To learn how to form an LLC, visit our Form an LLC state guides.

A DBA can only have Inc. in the name if the business entity the DBA is attached to is a corporation.

Holding a rental property in your name and with a DBA will not afford you any protection. The best option is to form an LLC to protect your personal assets in the event of an issue with the rental property. In any case, it is always best to consult an attorney.

Getting a DBA is often a better choice than changing your business’s legal name. If you want to rebrand your company or focus on another line of business, filing for a DBA is a simpler process than filing for a legal name change.

Some state-level laws prevent DBAs that are too similar to existing ones from being used, but this varies from state to state. It is possible to trademark a DBA, which would offer stronger protection across state lines.
