DBA vs. Fictitious Business Name: What Is the Difference?
There's no legal difference. "DBA" and "fictitious business name" describe the same type of filing, registering a name different from your legal one; the term that applies to you just depends on which word your state's statute uses. California and Florida call it a "fictitious business name" or "fictitious name" on their own forms, while "DBA" is the informal, nationally understood term people use regardless of a state's official wording.

The Core Answer: It's the Same Filing
"DBA" and "fictitious business name" aren't two different registrations you might have to choose between; they're two names for the same underlying idea: registering a name you do business under that isn't your legal name. If you've filed what your state calls a "fictitious business name statement," you've filed a DBA in the everyday sense of the word, and vice versa.
Why Two Terms Exist for One Thing
"DBA" is short for "doing business as," a plain-English phrase that describes what the filing is for, not a legal term defined by any specific statute. "Fictitious business name" is the literal term some states chose when writing their own statutes, describing the same concept from a different angle: the name is "fictitious" because it isn't the business's real, legal name. Over time, "DBA" became the everyday shorthand used in conversation, banking, and informal writing nationwide, regardless of which specific term a given state's law actually uses.
Where "Fictitious Business Name" Is the Official Term
California's own statute is titled the Fictitious Business Name law, found in the Business and Professions Code, and its filing is called a "fictitious business name statement." Florida's form, filed through the Division of Corporations, is officially named a "Fictitious Name Registration." If you're filing in either of these states, the paperwork itself will say "fictitious," not "DBA," even though everyone, including the state's own guidance in places, will still refer to it informally as a DBA.
Where Other Terms Are Used Instead
Many states use yet other words for essentially the same filing. Texas and New York call theirs an "assumed name" certificate. Some states, and some counties within states that don't run it statewide, use "trade name." Ohio is a useful example of why reading the actual form matters: its Secretary of State offers both a "trade name," which must be distinguishable and gives the registrant exclusive use of it in Ohio once granted, and a separate "fictitious name," a public notice filing that doesn't need to be distinguishable and grants no exclusive rights. These aren't just two labels for the same Ohio filing; they're two different products with different legal effects, so in a state like Ohio, confirming which one you actually want matters more than the general DBA-versus-fictitious-name question.
Why the Terminology Doesn't Change What the Filing Does
Regardless of which word your state uses, the filing itself generally works the same way: it's a public record of who's using a given name, it requires a form and a fee, and per the SBA, it doesn't provide legal protection by itself in any state, no matter what the filing is called there. None of these filings create a new legal entity, change liability protection, or give exclusive nationwide rights to a name; that requires a federal trademark through the United States Patent and Trademark Office, a completely separate process from any state's DBA, fictitious name, or assumed name filing.
How to Find Your State's Actual Term
The fastest way to know what to call your filing is to check your own state's Secretary of State or county clerk website and see what the form itself is titled. Searching "DBA" will usually get you to the right page regardless, since most state websites now use "DBA" somewhere in their guidance even if their statute uses different language, but the form you actually sign will use whatever official term your state has chosen.
Practical Considerations
Match the Term on Your Own Paperwork
When filling out a bank form, a license application, or a contract, use whatever term your own state's filing actually uses, rather than defaulting to "DBA" everywhere, since a form that specifically asks for your "fictitious business name number" expects that exact filing, not a generalized reference.
Don't Assume Every State's Version Works the Same Way
As the Ohio trade name versus fictitious name example shows, some states offer more than one type of name filing with real legal differences between them. Read your own state's specific definitions rather than assuming "DBA," "fictitious name," and "trade name" are always perfectly interchangeable everywhere.
Search Using Multiple Terms
When researching your state's requirements or searching for existing names, search using "DBA," "fictitious name," "assumed name," and "trade name" together, since a state's own search tool might be indexed under a term different from the one you'd naturally search for first.
Not Legal Advice
If a state offers more than one type of name filing with different legal effects, such as Ohio's trade name and fictitious name, confirm which one fits your situation with the filing agency or a business attorney before choosing.

Frequently Asked Questions
Is a fictitious business name statement the same as a DBA?
Yes, in states like California and Florida, "fictitious business name" or "fictitious name" is simply the official term for what's commonly called a DBA elsewhere.
Why does my state call it something other than DBA or fictitious name?
States chose different wording when writing their own statutes. Texas and New York use "assumed name," for example, but the filing serves the same purpose as a DBA or fictitious business name in other states.
Are a trade name and a fictitious name always the same thing?
Not necessarily. Some states, including Ohio, offer both as separate filings with different legal effects, so check your own state's specific definitions rather than assuming the terms are interchangeable there.
Does it matter which term I use when searching for DBA information online?
It can help to search using several terms, including DBA, fictitious name, assumed name, and trade name, since your state's own resources may be organized under whichever term its statute uses.
