"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."

"UPS' IHG code (108146) is for one of the world's largest package delivery companies. UPS has 500,000+ global employees and major hub in Louisville KY. IHG enforcement: Holiday Inn Express near UPS distribution centers (Louisville, Atlanta, Dallas, Newark) rarely checks; IHG InterContinental/Kimpton properties in business centers are more likely to verify. UPS employee IDs are physical company-issued photo badges recognizable to hotel staff. No specific UPS IHG denial incident documented in FlyerTalk."

"FedEx Freight American Freightways (954105683) is an IHG code for a FedEx freight division. The FedEx/IHG enforcement pattern applies across all FedEx business unit codes: IHG InterContinental properties request employee ID; IHG Holiday Inn Express properties essentially never do. FedEx's reported monitoring of hotel booking volume means anomalous usage could trigger company-side audit. FedEx employee IDs are standardized physical badges. Properties near FedEx facilities (Memphis TN, Indianapolis IN) are most verification-active."
