"Harvard University's Marriott code 17885 is an academic institutional code. No FlyerTalk thread discusses Harvard verification incidents. University codes at Marriott receive the lowest enforcement treatment — hotel staff view academic institutional rates as similar to government rates in terms of legitimacy. Harvard's Cambridge MA presence means nearby Marriott properties (Marriott Boston Cambridge, Sheraton Commander) are familiar with Harvard employees. No verification incident documented."

"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."

"I've been given codes for several chains from family/friends who are entitled to have them. All have assured me they have never been asked to provide company ID when checking in. In fact I was told they give the codes out to visiting clients who won't have ID anyway."
