I found some posts on this topic but the links to the database no longer work.
I tried searching on my own but could not find said database.
See if your school is on the U.S. Department of Education’s Database of Accredited Post Secondary Institutions and Programs (DAPIP) or the Federal Student Loan Program list. (from IRS web site)
U.S. Federal Student Aid Code List. (download)
