DBA vs. Trade Name: What Is the Difference?
In everyday use, "DBA" and "trade name" mean the same thing, and some states, including Arizona and Washington, use "trade name" as the formal term on their own DBA filing forms. Under federal trademark law, "trade name" has a narrower meaning: per 15 U.S.C. Section 1127, it's any name used to identify a business itself, as distinct from a trademark, which identifies the goods or services that business sells.

Comprehensive Guide
How States Use "Trade Name"
In ordinary business conversation, and on many states' own filing forms, "trade name" is simply the formal label for what's informally called a DBA. Arizona registers trade names with the Secretary of State as a separate process from LLC formation through the Corporation Commission. Colorado's Statement of Trade Name is filed with the Colorado Secretary of State and, for an LLC, stays effective for as long as the LLC remains in good standing, with no separate renewal required. Washington requires registering a trade name as part of the state's Business License Application, filed with the Department of Revenue rather than the Secretary of State. In all of these states, "trade name" is the exact filing other states call a DBA, fictitious name, or assumed name; it's the same kind of registration under a different label.
What "Trade Name" Means Under Federal Trademark Law
Federal trademark law draws a sharper distinction. Per 15 U.S.C. Section 1127, the terms "trade name" and "commercial name" mean any name used by a person to identify his or her business or vocation. A trademark, by contrast, is defined in the same section as a word, name, symbol, or device used, or intended to be used, to identify and distinguish specific goods, including a unique product, from those made or sold by others, and to indicate the source of those goods. In this federal sense, a trade name identifies the business itself (who's selling), while a trademark identifies particular goods or services (what's being sold) and who's providing them.
Why the Distinction Matters
A single business can have one trade name and several trademarks at the same time, and they don't have to match. A company might operate under the trade name "Riverside Manufacturing," while selling products under entirely different trademarked brand names for each product line. The trade name is how the business identifies itself on contracts, licenses, and state filings; the trademarks are how it identifies specific products or services to customers and competitors in the marketplace. Confusing the two can lead to a mistaken assumption that registering one protects the other.
Neither a State Trade Name Filing Nor the Term Itself Creates Trademark Rights
Registering a trade name with a state, regardless of whether that state calls it a trade name, DBA, or fictitious name, doesn't create the exclusive, nationwide rights a federal trademark registration through the USPTO provides. A state trade name filing is mainly a public record that a specific business is using a specific name in that state, and most state registries don't even check it against the national trademark database. If you want to stop others nationwide from using a confusingly similar name in connection with similar goods or services, you need a federal trademark registration, a separate and additional process from any state trade name or DBA filing.
Checking Which Meaning Applies to You
When you see "trade name" on a government form or a state's business filing site, it almost always means the same thing as a DBA: a registration letting your business operate under a particular public name. When you see "trade name" discussed in the context of trademark law, such as in a trademark application, a cease-and-desist letter, or a legal dispute, it's being used in the narrower federal sense, referring to how your business identifies itself as distinct from the goods or services it sells. Context tells you which meaning applies; the word itself is the same either way.
Filing a Trade Name Where Required
If your state uses "trade name" as its formal DBA term, the filing process works the same as any other state's DBA: search for name availability, file with the correct state or county agency, pay the fee, and track any renewal requirement. Arizona's trade name process runs through the Secretary of State, not the Corporation Commission that handles LLC formation, so confirm you're filing with the correct agency specifically for the trade name, separate from any LLC paperwork.
Practical Considerations
A Trade Name Search Isn't a Trademark Search
Searching your state's trade name registry only tells you whether that exact filing is available in your state; it doesn't tell you whether the name conflicts with an existing federal trademark. Search the USPTO's trademark database separately before committing to a name.
Legal Documents May Use "Trade Name" in Either Sense
When reading a contract, a franchise agreement, or correspondence from an attorney, check the context to see whether "trade name" refers to your state filing or to the federal trademark-law concept; the same word carries different legal weight depending on which is meant.
One Trade Name Filing Doesn't Cover Every Product Brand You Sell
If you sell multiple product lines under different brand names, your single trade name or DBA filing covers only the business's own operating name; each individual product brand that needs legal protection as a trademark has to be separately registered with the USPTO if you want that protection.
Not Legal Advice
The federal trademark-law meaning of "trade name" involves legal nuance beyond what a general overview can cover. Talk to a trademark attorney if a dispute or a contract hinges on this distinction.

Frequently Asked Questions
Is a trade name the same as a DBA in my state?
In most cases, yes. A number of states, including Arizona, Colorado, and Washington, use "trade name" as the formal term for the same filing commonly called a DBA elsewhere.
What's the legal difference between a trade name and a trademark?
Per 15 U.S.C. Section 1127, a trade name identifies a business itself, while a trademark identifies specific goods or services that business provides. They're legally distinct, and one business can have both.
Does registering a trade name with my state protect it like a trademark?
No. A state trade name filing is a public record of who's using a name in that state; it doesn't create the nationwide, exclusive rights that come from a federal trademark registration through the USPTO.
Can my business have a trade name and multiple trademarks at the same time?
Yes. Your trade name identifies your business as a whole, while each product or service brand you want legally protected as a trademark needs its own separate USPTO registration.
