The two main ways of finding out your federal student loan servicer’s identity are by either scrolling down to the “My Loan Servicers” section in your studentaid.gov account dashboard or calling the Federal Student Aid Information Center (FSAIC) at 1-800-433-3243. If you have a private student loan, then the lender is likely also your servicer, but you can look at your monthly loan statements or check the relevant online portal to confirm this.
