"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."

"This Deloitte code circulates widely among current and former staff. IHG auditing materials note that large firms like Deloitte and IBM have codes hard-coded into IHG's auditing software to trigger a request for ID. The "Stop at Desk" flag has been observed: certain high-value codes block issuance of a Digital Key until physical ID is presented at the front desk."

"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."
