A "DBA", also known as an "assumed name", is typically completed by making a filing at the county level where the business is located. This filing does not change the official name of the corporation; however, it allows the company to use additional names.
A merchant's legal business name as differentiated from the names of a company's principals or other entity that owns or manages the business. A DBA that is significantly different from the principals' or other entity's name can result in an unrecognizable merchant name, or descriptor, on a cardholder's monthly Visa statement, which can in turn lead to potential copy requests and chargebacks.
A company whose operating name differs from its legal name is said to be "doing business as" the operating name. Some states require DBA or "fictitious business name" filings to be made for the protection of consumers conducting business with the entity.
The phrase "doing business as" (abbreviated DBA or d/b/a) is a legal term, meaning that the name of the business or operation does not include the legal name of its proprietor, the names of all partners, or the official registered name of the limited partnership or corporation that owns it.
