Uses for a DBA
The most significant use of a DBA is the ability for a sole proprietorship to open a business bank account and collect money using a name other than its legal name.
In many cases, more than one business can operate under the same DBA. There is no protection or exclusivity offered by operating solely under a "doing business as" name. When registering your DBA, you may also find a corporation, LLC, sole proprietorship or other business entity using the same or a similar business name.
