"University of Pennsylvania's Marriott code 4309 is an academic institutional code. No FlyerTalk thread discusses UPenn verification incidents.

"I have never been asked for proof the maybe 5 times I've used my corporate code but I at least keep my business cards with me"

"I'm guessing so, but I'm not a Marriott employee. Also, to answer some of the other questions floating around here, I have never been asked to produce my work ID when checking into the hotel that I booked using a corporate rate. I travel half a dozen times a year."

✅ Generally low risk
This code is rarely verified. Still, always compare prices — public rates sometimes beat corporate codes.
