A DBA, also called Doing Business As, is a registered alias that an individual or business uses rather than their legal name. It allows businesses to market under a different name while preserving the legal name for contracts and official documents. Depending on the state, a DBA may also be called a trade name, fictitious name, or assumed name.
Note that a DBA is not a legal business entity. It does not create a separate legal structure like an LLC, corporation, or partnership does. Regardless of the naming convention used in a state, a DBA is a name registration that generally allows a business to operate under a different name than its legal one. It does not create liability protection, tax status, or separate legal existence for the owner.
The primary purpose of a DBA is consumer protection. When a business uses a name besides its legal name, most states require that name to be registered through a DBA filing. This step ensures that the public has a way to identify the actual person behind the business. Hence, a DBA creates a public link between the business name and the real owner.
