What is a DRN number?
DRN stands for Data Release Number. It is a 4-digit number listed on the FAFSA filing confirmation page, in addition to the longer Filing Confirmation Number. The DRN is also listed on the Student Aid Report (SAR).
If you call the Department of Education's Federal Student Aid office about a FAFSA application that has already been filed, they may require you to provide your DRN number.
