"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."

"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."

"FedEx's main IHG code (109207) is documented in the FlyerTalk IHG Rate Codes master thread. The IHG enforcement pattern for FedEx: "Airport Holiday Inns rarely check credentials; InterContinentals in major cities almost always do." FedEx monitors hotel usage volume with IHG — anomalous usage in one business unit could trigger company-side audit. One FlyerTalk user documented IHG refusing to honor a rate without ID and offering to cancel after the cancellation deadline. FedEx employee IDs are physical company badges recognizable to hotel staff."
