"hotelcorporatecodes.com explicitly places McDonald's N1360871 in the "Rarely" / no ID check required category alongside BASF, Dow Chemical, Nestlé, and Coca-Cola. milepro.com notes: "Franchisee-heavy companies like McDonald's present ambiguous affiliation — a franchisee employee, a corporate employee, and a supplier may all legitimately use the code, making front-desk challenges impractical and uncommon.""

"The Hilton BP International code is listed as active with up to 15% discount. No specific FlyerTalk thread or Reddit post documents a verification denial for this code. BP is a globally recognized energy company, but enforcement is reactive (when the hotel is busy or the discount is steep), not proactive. Hilton's verification is reported as inconsistent — roughly 20% of stays for legitimate codes — but no BP-specific incident was documented."

"No specific forum reports of verification incidents found for the Disney Hilton code. Disney has one of the largest US workforces, meaning the code is widely distributed and hotels near Disney properties are accustomed to seeing it. Hilton's general 20% verification rate applies. The large and diverse Disney employee base makes stringent verification less practical. Fishbowl discussions about hotel codes focus on consulting firm codes, with Disney not emerging as a frequently discussed verification concern."
