"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'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."

"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."
