"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."

"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."

"Kraft's IHG code (105406) is a food and beverage corporate code. Kraft Heinz (as it's now known) HQ is in Chicago IL and Pittsburgh PA. IHG enforcement: Holiday Inn Express essentially never checks food company codes; Crowne Plaza occasionally. No Kraft+IHG specific verification incident documented. Consumer packaged goods codes at IHG follow the same pattern as McDonald's and Coca-Cola: low scrutiny due to ambiguous franchise/supplier affiliation."
