What box is the IRS using when comparing the Name Control to the tax return?

 

Are they looking at both the individual name and the business name or one or the other?

 

For example if my name is John Doe my name control is DOE and my business name is "Generic Company" Are they going to match this with the business name or just the last name on the return? If the business name then "Generic Company" would not match the Name control.
