I mean, you're dealing with a planetary megacorp. I know it's facebook, but you should expect to have to fax something and be ready to pull out a DUNS number, SOW, and MSA. The fact that you don't is a miracle.
A DUNS number is a 9-digit business ID number from Dun & Bradstreet. Apple requires you to have one if you want to create an organization developer account for the App Store. See http://blog.metamorphium.com/2012/12/03/apple-duns/
