"University of Texas' IHG code (99502056) is an academic institutional code. IHG enforcement: Holiday Inn / Crowne Plaza near UT Austin essentially never verifies academic rates. InterContinental Austin (if applicable) might theoretically ask, but university codes are the lowest-enforcement category across all IHG properties. No UT+IHG verification incident documented in public forums."

"Dell's IHG code (954284898) is listed in the FlyerTalk IHG Rate Codes master thread but community members have noted: "the codes are generally not giving any significant discount — maybe 6 to 10% at the most. In some cases, the corporate rate essentially just gives you a refundable rate at the same price as the non-refundable rate." Low discount spread means low enforcement motivation. The practical consensus is that a sub-10% discount at Holiday Inn / Crowne Plaza tier rarely triggers ID requests. Risk rises at InterContinental properties, but overall Dell's IHG code is among the lower-risk corporate codes given the minimal discount depth."

"That being said, I've never been asked to provide any proof. It's not something I just do all the time, but I've never had any problems when I have."
