"Coca-Cola's IHG code (128813) is for one of the world's most recognized brands. IHG enforcement is tier-based: InterContinental Atlanta (near Coke HQ in Atlanta GA) regularly sees Coke employees and has established verification procedures. Holiday Inn Express: essentially never checks. Coca-Cola has dedicated travel partnerships with major hotel chains — the contract likely specifies usage verification protocols. hotelcorporatecodes.com notes Coke codes at "⚠️ Sometimes" at IHG."

"UPS' IHG code (108146) is for one of the world's largest package delivery companies. UPS has 500,000+ global employees and major hub in Louisville KY. IHG enforcement: Holiday Inn Express near UPS distribution centers (Louisville, Atlanta, Dallas, Newark) rarely checks; IHG InterContinental/Kimpton properties in business centers are more likely to verify. UPS employee IDs are physical company-issued photo badges recognizable to hotel staff. No specific UPS IHG denial incident documented in FlyerTalk."

"FedEx Supply Chain Services (100172336) and FedEx Trade Networks (970001266) are IHG codes for FedEx supply chain and trade services divisions. The same FedEx IHG enforcement pattern applies: tier-dependent verification at IHG properties. FedEx Supply Chain has major facilities in Memphis, Pittsburgh, and across the US Southeast — IHG Holiday Inn properties near those facilities are familiar with FedEx employee badges. FedEx Trade Networks focuses on international freight logistics; international IHG InterContinental properties carry higher verification risk."
