"Toyota's IHG code (954409548) follows the same low-enforcement pattern as Toyota's Marriott code (TOY), which is confirmed as 'Rarely' checked in FlyerTalk's master codes list. Toyota's IHG travel concentrates near manufacturing hubs (Georgetown KY, San Antonio TX, Princeton IN) at Holiday Inn Express and Crowne Plaza properties — property types with minimal verification infrastructure. No Toyota IHG verification incident documented."

"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."

"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."
