What is the MPN?
The master promissory note (MPN) essentially opens a line of credit for education expenses during your academic career. When you sign a Federal Stafford Loan promissory note, you promise to repay your student loan(s). The note also includes important language about your rights and responsibilities as a borrower. The MPN replaced the Common Federal Stafford Application and Promissory Note for all Federal Stafford Loans on July 1, 2000.
