"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."

"A former Siemens employee posting on FlyerTalk noted: "When checking in as a group of Siemens employees, we were never asked for ID. However, when traveling alone, front desk staff often asked for some form of ID." IHG enforcement is highly fragmented across its franchise network. Siemens's code falls into the mid-tier corporate bucket. At InterContinental/Kimpton properties, verification is near-certain; at Holiday Inn Express, essentially never. IHG's 2018 T&C update explicitly added unauthorized corporate rate use as grounds for account closure."
