Short answer
A trade name names a business. A trademark identifies the source of goods or services offered to customers. One name can do both jobs, but merely registering a business name is not the same as establishing trademark rights in that name. 1 2
The same wording can be both a trade name and a trademark, but using a business name does not automatically make it a mark.

What each thing is
Trademark. A word, phrase, design or other sign used to identify and distinguish the source of goods or services. 1
Trade name. The name under which a business operates or identifies itself. 2
Key differences
The issue is how a name is used in commerce. A sign on goods, packaging or service advertising can function as a mark. A company name appearing only in an entity filing may identify the legal business without telling consumers the source of particular offerings. Trademark registration and business-name registration follow different processes. 1 2
How to tell them apart
Ask what the wording identifies to customers. If it distinguishes a seller’s goods or services, analyze trademark use. If it simply names the company in corporate records or invoices, analyze trade-name use. Check actual use rather than assuming the words’ appearance determines their legal role. 1 2
Where they overlap
A small company may put its legal name on storefront signs and product labels, making that same text both a trade name and a mark. Both can matter when choosing a new business identity. 1 2
Edge cases
A name’s use can change over time; a trade name may become source-identifying. State entity registration does not necessarily resolve federal trademark conflicts. The distinct legal rights depend on facts and jurisdiction. 1 2
Why the distinction exists
US law separates business identity from marketplace source identification. Consumers need to distinguish who supplies products or services, while businesses also need formal names for operations. 1 2
Common misconceptions
“I registered the company name” is not proof that no one else has trademark rights or that the company owns a federal trademark registration. 1 2
Examples
“Blue Harbor LLC” in incorporation papers is a trade name or legal business name. If “Blue Harbor” appears as the brand on its coffee bags, the wording may also serve as a trademark. 1 2
