After you file

So was her info correct, or not?  This is just a guess, but the IRS may have implemented more stringent rules to fight identity theft.  For example (my example, not the IRS's), maybe only the first 4 letters of her name had to agree with her SSN before, but now the first 6 do.  (For security reasons, the IRS does not disclose all the checks that they make.) What exactly did the rejection message/code say?
