"ConocoPhillips' IHG code (262552) is an energy company code. ConocoPhillips HQ is in Houston TX with major operations globally. IHG enforcement is tier-based: InterContinental properties near Houston (Energy Corridor) encounter ConocoPhillips employees regularly and have established verification processes. Holiday Inn Express: minimal enforcement. ConocoPhillips is a "major" oil company with recognizable employee credentials. No specific 262552 denial documented in FlyerTalk."

"Only once was I asked, by a new room (revenue) manager of a hotel I've used extensively. Explained that the code was provided by my contact at the company, offered to provide his information, and that contractors were included and allowed to use the code. Never had a problem."

"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."
