🏷️ How to Register a DBA or Trade Name
A DBA—also called an assumed, fictitious, or trade name—lets a person or entity operate under a name different from its legal name. Requirements depend on the business structure and location.
The U.S. Small Business Administration notes that registration may be handled by a state, county, or city. A DBA filing does not by itself create a separate legal entity or provide trademark protection.
Check name availability, publication rules, local licenses, bank requirements, renewal dates, and whether the name also needs state tax or sales-tax registration.

Frequently asked questions
Does a DBA create an LLC?
No. It is a name registration, not a new legal entity.
Does a DBA give trademark rights?
Not by itself. Trademark rights and federal registration are separate issues.
Can multiple businesses use similar DBAs?
Rules vary and name availability does not eliminate trademark or unfair-competition risk.
