"ConocoPhillips' IHG code (262552) is an energy company code. ConocoPhillips HQ is in Houston TX with major operations globally. IHG enforcement is tier-based: InterContinental properties near Houston (Energy Corridor) encounter ConocoPhillips employees regularly and have established verification processes. Holiday Inn Express: minimal enforcement. ConocoPhillips is a "major" oil company with recognizable employee credentials. No specific 262552 denial documented in FlyerTalk."

"FedEx Ground is one of several FedEx business unit codes in IHG's GDS system. The general FedEx IHG pattern documented on FlyerTalk: IHG has been "very careful" in recent years about verifying codes at full-service brands. FedEx Ground staff IDs are company-standard. Properties near FedEx Ground hubs (Indianapolis, Memphis) are more familiar with FedEx employee badges and may request them. Holiday Inn Express near distribution centers: essentially never check."

"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."
