"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."

"Electronic Data Systems (EDS) IHG code (136905) follows the same profile as EDS Marriott — a widely-circulated code from a company now absorbed into HP/DXC Technology. FlyerTalk's IHG Rate Codes 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." EDS employee credentials (badges) no longer exist post-HP acquisition, which could complicate verification. IHG InterContinental: likely to ask; Holiday Inn Express: rarely."

"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."
