"FedEx has multiple IHG codes covering different business units (FedEx Ground, FedEx Freight, FedEx Supply Chain). FlyerTalk's dedicated FedEx hotel rate thread notes: "FedEx reportedly monitors hotel usage volume — inflated usage could affect their contract negotiations." IHG enforcement follows brand-tier pattern: InterContinental/Kimpton properties may request ID; Holiday Inn Express essentially never checks. FedEx employee IDs are standard-issue company badges and well-recognized. One user warned of being charged rack rate after failing to produce credentials at a Crowne Plaza."

"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."

"Once you are past cancelation deadline either advance rate or flex, and obviously your CC is provided when originally booking, if your hotel asks for corporate ID of your corporate rate and you can not comply, the hotel will simply charge you the correct higher rate."
