"General Electric's IHG code (102806) reflects GE's massive global travel volume. FlyerTalk specifically documented IHG escalating GE code enforcement: "In the past two years, IHG has been very careful in checking on people using IBM and GE corporate rates. Not only corporate ID is required, also an email from IBM or GE to confirm staff identity in extreme cases." At Holiday Inn Express tier: essentially no enforcement. At InterContinental tier: near-certain verification and potential email confirmation. GE's 70% discounts at some InterContinentals trigger automatic audit flags."

"The only legitimate reason the hotel needs is that the company is giving permission, for whatever reason, for that individual to stay on the corporate rate. Since my uncle is THE guy to ask permission from, I see that to be a perfectly legitimate reason, and the paperwork (that so far has never actually been produced) would not be fake."

"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."
