"JC Penney's Hilton code N0381437 is a retail corporate code. Hilton's general corporate verification rate of ~20% applies primarily to full-service urban properties. JC Penney's suburban mall-anchor presence means most JCP-related hotel stays are at select-service properties (Hampton, Hilton Garden Inn) where enforcement is minimal. JC Penney's workforce reduction following bankruptcy further reduces the volume of legitimate JCP code users."

"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."
