"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."

"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."

"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."
