The National Student Loan Data System (NSLDS) has a loan locator service that can answer questions about your lender/s and federal aid. The NSLDS website displays information about any outstanding balances, loan statuses, and disbursements. Upon viewing your loan history, if you should have any questions, please call 1-800-4-FED-AID. If you need to resolve conflicting information about your loan status or have questions about a particular loan, please contact your lender or guarantor listed for that loan in NSLDS.
