A Assumed Business Name is the same as a trade name. It is the name of the business when officially registered with the government. For example, you do business as a sole proprietor using the business name "Best Widgets Company". The business name is called an Assumed Business Name, or fictitious firm name (as in Nevada).
In other states, it goes by a fictitious business name, as in California, and assumed business name in Texas or Business Name Certificate in New York etc. It is also known as Doing Business As ( DBA ) because a business is doing business as a certain name as in the example above.
