"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."

"Target's IHG code (888400) is a major retail chain code. IHG enforcement is tier-based: InterContinental and Kimpton properties are more likely to verify; Holiday Inn Express essentially never checks. Target's code circulates widely online, which is specifically called out in FlyerTalk's IHG thread: "A moderator explicitly cautioned — unless you're employed by one of those companies, I would avoid using these codes at all. They do often ask for ID." Target employees near Minneapolis HQ and major distribution centers may be verified at full-service IHG properties."
