HW is correct, it is Upenn alumni association.

I'm a Penn alum, and I have received three calls from this number in the last two days.  I guess it makes sense but damn put some kind of ID on the call if you want to solicit alums for donations.

Must be a Penn alum as everyone says here.  I don't pick up unknown numbers these days-- Google first!

Yup, it must be related to Penn alumni. Didn't pick up, though.

Are you a Penn grad, it might be the alumni association.
