"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."

"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."

"Enforcement is highly fragmented across brand tiers. At Holiday Inn / Holiday Inn Express: minimal enforcement. At InterContinental and Kimpton: almost always verify. One user stated: "Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do." Properties near Seattle headquarters offer deeper discounts but face stricter verification."
