A tradename is the name your business is known by. It is also commonly referred to as a DBA.
A DBA or tradename can be different than your legal business name. As an example, your legal business name might be Sally Smith LLC, but your tradename is “Sally’s Interior Design.”
Tradenames are legal to use when doing business and usually must be registered through your local or state government. One business might have multiple tradenames or DBAs.
Corporations, LLCs, Partnerships and sole proprietors are all eligible to register a tradename.
