Doing Business As (DBA) is a term used to describe a business name that is different from the legal name of the company. A DBA is also sometimes called a trade name or a fictitious business name.
For example, let's say a company is incorporated under the name "ABC Corporation," but it wants to operate under the name "XYZ Designs." In this case, the company would need to register a DBA to use the name "XYZ Designs" for its business.
