"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."

"Ace Hardware's IHG code (100862437) is a retail cooperative corporate code. No FlyerTalk or Reddit discussion found specifically about Ace Hardware IHG verification. Retail sector codes at IHG Holiday Inn Express properties are essentially never verified. Ace Hardware is a dealer cooperative, not a traditional employer — verification of "Ace employee" status is inherently ambiguous. IHG enforcement is tier-based: InterContinental properties might ask; Holiday Inn Express properties rarely do."
