"FlyerTalk's dedicated thread "AAA card – Do hotels check?" documents: "One frequent traveler staying 1-3 hotels per week was asked for the AAA card at about 10-15% of hotels." Another reported being asked only twice in 70-80 stays. The IHG/AAA discount is officially listed on IHG's website as a membership benefit — unlike corporate codes, this is a publicly advertised member rate. AAA rates are typically only 5-15% off, reducing hotels' incentive to verify."

"Arizona State University's IHG code (ASU) is an academic institutional code. University codes at IHG properties are used primarily for conference and academic travel. No FlyerTalk thread discusses ASU IHG verification incidents. Academic/education sector codes at IHG are the lowest-enforcement category — holiday Inn / Crowne Plaza near Phoenix (where ASU's main campus is located) are familiar with ASU travelers and rarely request ID."

"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."
