"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."

"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."

"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."
