"Oracle's IHG code appears in FlyerTalk's "List of IHG Rate Codes" thread. A FlyerTalk 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." IHG enforcement is tier-dependent: InterContinental and Kimpton properties enforce eligibility most strictly while Holiday Inn Express shows minimal enforcement. One FlyerTalk user documented IHG refusing to honor a rate without ID and offering to cancel the reservation after the cancellation deadline."

"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."

"FedEx Freight American Freightways (954105683) is an IHG code for a FedEx freight division. The FedEx/IHG enforcement pattern applies across all FedEx business unit codes: IHG InterContinental properties request employee ID; IHG Holiday Inn Express properties essentially never do. FedEx's reported monitoring of hotel booking volume means anomalous usage could trigger company-side audit. FedEx employee IDs are standardized physical badges. Properties near FedEx facilities (Memphis TN, Indianapolis IN) are most verification-active."
