Contact the original lender of your PLUS Loan(s). The lender that initiated the loan will maintain your account records for a set period of time even if it sells your loan to another company. Lenders offering a life-of-loan service will update your records regardless of how many times your loan has been sold until your debt is paid in full. If the company sells your account and doesn't maintain records after the transaction, it will still have the new lender's contact information. You may have to contact several lenders before you find the company currently holding the loan.
Use the National Student Loan Data System (NSLDS), which acts as a central database for federal student loans. To access the site, you need a personal identification number (PIN). You can apply for a PIN by visiting the Federal Student Aid PIN website. Once you have a PIN, you can create an account with NSLDS and access your Federal PLUS Loan information.
Talk with a financial representative at the college that received funding from the loan. If the college doesn't have you listed on the student's records, the representative won't give you the requested information. In this case, have the student make the request. Financial records contain the amount of the loan and the original lender. Although the college won't necessarily have records indicating the sale of your loan, you can use the original lender information to help you track down the current lender.
Get a copy of your credit report. Federal lenders offering PLUS Loans report your payment history to at least one of the three credit reporting agencies in the United States. In some cases, you can get a free copy of the report from Equifax, Experian, or TransUnion. The report should show the loan origination even if you haven't begun repayments. Your credit report should have the lender's name as well as a contact phone number for the lender.
