Direct Loans may now be serviced by one of five service centers. It is the goal of the Department of Education that all of your Direct Loans will have the same servicer. To find out who is servicing your loan(s), please log onto the National Student Loan Data System (NSLDS) and view the individual loan(s). Each will list the servicer with their customer service contact information. Customer Service Centers include Direct Loan Servicing (ACS), Great Lakes, Nelnet, Fedloan (PHEAA), and Sallie Mae.
