"FedEx has multiple IHG codes covering different business units (FedEx Ground, FedEx Freight, FedEx Supply Chain). FlyerTalk's dedicated FedEx hotel rate thread notes: "FedEx reportedly monitors hotel usage volume — inflated usage could affect their contract negotiations." IHG enforcement follows brand-tier pattern: InterContinental/Kimpton properties may request ID; Holiday Inn Express essentially never checks. FedEx employee IDs are standard-issue company badges and well-recognized. One user warned of being charged rack rate after failing to produce credentials at a Crowne Plaza."

"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."
