What if I do not have the reference number or co-sign code?
Then you should contact the IDR applicant because an email was sent to them containing the reference number or co-sign code.
I do not know where the reference number or co-sign code is, how can i get it?
Just ask your spouse because an email was sent to him or her and the IDR applicant can also access the number by logging in to StudentAid.gov.
