trade name

A trade name, also known as a trading name, business name or operating name, is a pseudonym used by companies and other organizations that do not operate under their registered legal name. Registering the trade name with a relevant government body is often required.

In a number of countries, the phrase "trading as" (abbreviated to t/a) is used to designate a trade name. In the United States, the phrase "doing business as" (abbreviated to DBA, dba, d.b.a., or d/b/a) is used, among others, such as assumed business name or fictitious business name. In Canada, "operating as" (abbreviated to o/a) and "trading as" are used, although "doing business as" is also sometimes used.
