"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."

"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"
