"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."

"The Walmart IHG code is widely discussed online. Analysis confirms: "IHG might occasionally ask for verification, such as a Walmart employee ID, upon check-in. IHG may cross-reference submitted information with Walmart's employee database." Enforcement is tier-based: airport Holiday Inn Express properties rarely check while InterContinentals almost always do. With 1.6M+ US Walmart employees, hotel staff are familiar with what Walmart IDs look like, making false affiliation claims harder to sustain."

"Yesteryear it wasnt so risky sinc ethe CX policy was Day of @ Check-in time, so as long as you got there before the CX time was past, then if carded all you had to say was OK CX the res then. That doesnt exist any longer as its now 24 hrs before if not earlier, so no ID they simply will charge the CC you used when you made the res , forget about Disputing it as the hotel will produce the res and their CX policy and that you used a code that you werent entitled to use"
