"FedEx Custom Critical (954288433) is an IHG code for FedEx's expedited shipping division. FedEx's general IHG code enforcement: IHG has escalated monitoring of FedEx codes in recent years, with InterContinental properties requesting employee ID. FedEx monitors hotel usage volume across business units — inflated usage in any unit could flag a code for review. Holiday Inn/Express tier: minimal enforcement. Crowne Plaza and InterContinental: moderate enforcement. One FlyerTalk user documented being charged rack rate at a Crowne Plaza after failing to show FedEx credentials."

"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."

"Only once was I asked, by a new room (revenue) manager of a hotel I've used extensively. Explained that the code was provided by my contact at the company, offered to provide his information, and that contractors were included and allowed to use the code. Never had a problem."
