"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."

"FedEx's main IHG code (109207) is documented in the FlyerTalk IHG Rate Codes master thread. The IHG enforcement pattern for FedEx: "Airport Holiday Inns rarely check credentials; InterContinentals in major cities almost always do." FedEx monitors hotel usage volume with IHG — anomalous usage in one business unit could trigger company-side audit. One FlyerTalk user documented IHG refusing to honor a rate without ID and offering to cancel after the cancellation deadline. FedEx employee IDs are physical company badges recognizable to hotel staff."

"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."
