"Honda 100371240 is confirmed in the FlyerTalk IHG rate codes thread, where a moderator immediately responded: "Unless you're employed by one of those companies, I would avoid using these codes at all. They do often ask for ID." Honda employees travel heavily to IHG properties near manufacturing hubs (Ohio, Indiana, Alabama) which are predominantly Holiday Inn / Crowne Plaza tier — mid-range enforcement. The 9-digit code format is consistent with large-account codes that IHG's system flags for verification."

"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."

"Electronic Data Systems (EDS) IHG code (136905) follows the same profile as EDS Marriott — a widely-circulated code from a company now absorbed into HP/DXC Technology. FlyerTalk's IHG Rate Codes thread: "A moderator explicitly cautioned: unless you're employed by one of those companies, I would avoid using these codes at all. They do often ask for ID." EDS employee credentials (badges) no longer exist post-HP acquisition, which could complicate verification. IHG InterContinental: likely to ask; Holiday Inn Express: rarely."
