"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."

"This Deloitte code circulates widely among current and former staff. IHG auditing materials note that large firms like Deloitte and IBM have codes hard-coded into IHG's auditing software to trigger a request for ID. The "Stop at Desk" flag has been observed: certain high-value codes block issuance of a Digital Key until physical ID is presented at the front desk."

"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."
