"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."

"I work for BofA and the internal discounts website didn't list codes, instead directing employees to contact individual properties. I later confirmed the code is 109568. Unless you're employed by one of those companies, I would avoid using these codes. They do often ask for ID at InterContinental properties, though Holiday Inn locations rarely enforce."

"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."
