"Honda 100371240 is confirmed in the FlyerTalk IHG rate codes thread, where a moderator immediately responded: "Unless you're employed by one of those companies, I would avoid using these codes at all. They do often ask for ID." Honda employees travel heavily to IHG properties near manufacturing hubs (Ohio, Indiana, Alabama) which are predominantly Holiday Inn / Crowne Plaza tier — mid-range enforcement. The 9-digit code format is consistent with large-account codes that IHG's system flags for verification."

"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."

"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."
