No, not UCI because then it would have 824 as first 3 numbers. I saw on another website someone thinks its regarding donations. I've never answered, nor ever gotten a msg and when I try calling back, I get busy signal.
Yes, the UCI TELEPHONE OUTREACH PROGRAM.

UC Irvine's Telephone Outreach Program (T.O.P.) is a part of the UCI Fund and plays an integral role in providing alumni, parents, friends, and students with the information you need to stay in touch with UCI. From school rankings to a first-person perspective of student life, our callers are eager to share their UCI experience with you. And they play a critical role in reaching UCI supporters, many of whom choose to make a gift over the phone.
