As the sole member of ABC LLC, would/could the member file their name-Aaron J Jones or Alt/ AJ Jones as a DBA since many sites and purchases request a first and last name, not biz name?

State law allows a sole proprietorship to use a name other than the owner's legal name to conduct business only if the business name is registered with the state as a fictitious business name, also known as a “doing business as” or DBA;you, as a A sole proprietorship can have more than one DBA and can have DBAs in more than one state, provided the names are properly registered before use. Any name used for business that doesn’t contain the legal name of the owner/sole proprietor is called a fictitious business name
