"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."

"Code 150711 is confirmed in the FlyerTalk IHG rate code master list alongside Microsoft (100857558) and IBM (000243132). IHG enforcement: some franchises instruct staff to ask all guests; others only ask if discount is better than 15% of flex rate. IHG T&Cs explicitly list using corporate rates without entitlement as grounds to close IHG account. Holiday Inn Express: minimal enforcement; InterContinental/Kimpton: almost always verify."

"HotelCorporateCodes.com rates Walmart IHG code 293512 as "Sometimes." IHG properties near Walmart's Bentonville AR HQ enforce verification more strictly — hotels that see the same corporate code 50 times a day become experts at identifying valid employee badges. Standard IHG pattern: Holiday Inn Express/Candlewood rarely verify; InterContinental/Kimpton almost always verify. Walmart code works well at mid-tier IHG properties in most US markets outside Bentonville."
