"Coca-Cola's IHG code (128813) is for one of the world's most recognized brands. IHG enforcement is tier-based: InterContinental Atlanta (near Coke HQ in Atlanta GA) regularly sees Coke employees and has established verification procedures. Holiday Inn Express: essentially never checks. Coca-Cola has dedicated travel partnerships with major hotel chains — the contract likely specifies usage verification protocols. hotelcorporatecodes.com notes Coke codes at "⚠️ Sometimes" at IHG."

"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."
