"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.

"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."
