"FedEx Supply Chain Services (100172336) and FedEx Trade Networks (970001266) are IHG codes for FedEx supply chain and trade services divisions. The same FedEx IHG enforcement pattern applies: tier-dependent verification at IHG properties. FedEx Supply Chain has major facilities in Memphis, Pittsburgh, and across the US Southeast — IHG Holiday Inn properties near those facilities are familiar with FedEx employee badges. FedEx Trade Networks focuses on international freight logistics; international IHG InterContinental properties carry higher verification risk."

"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."

"Bayer 251321 is confirmed as an IHG corporate code. IHG enforcement is highly brand-dependent: milepro.com states "At InterContinental or Kimpton, you'll almost certainly need to show proof of eligibility" while "Holiday Inn Express properties rarely check." Bayer's heavy presence at InterContinental properties in European pharma hubs (Frankfurt, Basel, London) means real-world usage skews toward high-enforcement properties. FlyerTalk on IHG code verification: "They do often ask for ID. YMMV." Rated Medium because enforcement is brand-split."
