Your  loan repayment start date depends on the type of loan you borrowed. You are  required to begin making payments on time, even if you have not received a  payment notice or statement from your loan holder. If you do not receive a  payment notice, request one from your loan holder immediately.

To   find contact information for the loan servicer or lender for your loans, visit the National   Student Loan Data System (NSLDS®). You will need the PIN you established when completing the FAFSA to access your   information
