"Philips' IHG code (953100013) is for the Dutch electronics and healthcare company. IHG enforcement is brand-tier dependent: InterContinental properties in Amsterdam (Philips' HQ city) and other European markets are most likely to verify. Holiday Inn Express properties in the US: essentially never check. Philips has major operations across Europe, North America, and Asia — IHG InterContinental in those regions carries moderate verification risk. FlyerTalk general IHG warning: "They do often ask for ID at full-service properties.""

"Only once was I asked, by a new room (revenue) manager of a hotel I've used extensively. Explained that the code was provided by my contact at the company, offered to provide his information, and that contractors were included and allowed to use the code. Never had a problem."

"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."
