What Address Can I Use for My California Fictitious Business Name (FBN) Filing?

If you’re registering a business under a name that isn’t your own, you’ll need to file a Fictitious Business Name (FBN). Many entrepreneurs get stuck wondering what address they can use, and that’s where mistakes happen. Understanding California Fictitious Business Name address is critical because the wrong address could delay your filing or even cause legal issues later on.

ZworkSpace offers flexible office and mailing solutions in Fullerton, CA that meet California’s FBN requirements. We give entrepreneurs, freelancers, and startups a professional business presence without the commitment of a long-term lease.

What Is a Fictitious Business Name (FBN) in California?

A Fictitious Business Name (sometimes called a “Doing Business As” or DBA) is the public registration of your business name with your county. It ensures transparency by letting customers know who’s behind a business. If you’re operating under anything other than your legal name, California law requires you to file an FBN with your county clerk’s office.

What Are the Address Requirements for a California FBN?

When filing, you must provide:

• A physical street address in California where your business is located

• The principal place of business — not just a mailing address

• No P.O. boxes allowed

The county uses this address for public records, so it must be accurate and accessible.

Can I Use a Virtual Office for My FBN Filing?

Yes — if it meets California’s requirements. A virtual office address from ZworkSpace includes a physical street address in Fullerton, which qualifies for most county FBN filings. The key is that the address must be an actual location where business records can be kept or where someone can receive official notices.

Benefits of using a ZworkSpace virtual office for your FBN:

• Professional business address in Orange County

• Mail handling and forwarding services

• Privacy protection (keeps your home address off public record)

• Month-to-month flexibility

What If I Work From Home?

You can use your home address for an FBN — but it comes with risks:

• Your home address becomes public information

• Less professional image for clients and partners

• Potential zoning restrictions depending on your city

Many home-based business owners choose a virtual office to avoid these issues.

How to File Your FBN with the Right Address

1. Choose your address — decide between home, brick-and-mortar, or virtual office

2. Check your county’s requirements (some counties have extra rules)

3. Complete your FBN application online or in person

4. Publish your FBN in an approved local newspaper (required in California)

5. Renew every 5 years or when your address changes

FBN Address Mistakes to Avoid

• Using a P.O. box as your main business address

• Providing an address in a different state

• Listing an address you cannot legally occupy

• Failing to update your address after moving
