"GE's IHG code is directly mentioned in FlyerTalk: "The GE code brings a Holiday Inn rate down from $114 to $84." A more recent thread warns: "In the past two years, IHG has been very careful in checking on people using IBM and GE corporate rates. Not only corporate ID is required, also an email from IBM or GE to confirm staff identity in extreme cases." GE's documented 70% discount at InterContinental Chicago makes it a high-audit-trigger code at luxury IHG properties. Holiday Inn Express tier: low risk. InterContinental/Kimpton tier: high risk, consistent with the brand-tier pattern across all IHG properties."

"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."
