I just received the same letter in the mail, wanted to search to internet to see if this is a scam before I call and give out any of my personal information.  The letter says its a secure document from:
Student Loan Division
1133 Westchester Avenue S-223
White Plains, NY 10604 USA
1-888-626-0307

Can someone confirm on deny if this is a scam, I could really use the relief but I don't want to be scammed in the process.

Thanks
