How is a Name/TIN mismatch identified?
A Name/TIN combination is incorrect if it doesn’t match or can’t be found on IRS or SSA files. An example of a Name/TIN mismatch is when an individual name is submitted with an EIN. Your TIN is not interchangeable with different names. A business EIN must be used for a partnership, corporation, or Limited Liability Company (LLC). A SSN must be used with an individual name. A sole proprietor must his/her individual name, but may also provide his/her DBA name.
