"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."

"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."

"IHG corporate codes vary by brand. Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do. The likelihood of a request for ID is based on the size of the discount — the greater the discount, the more diligent the front desk. Be prepared to be asked for company ID if the discount rate is more than the standard 15% given to most corporates, or if the company rate is a fixed rate lower than the hotel's ADR. Cisco's IHG code (954410926) sits alongside IBM and Dell in the widely-circulated FlyerTalk master list; tech-company codes at this tier typically yield 10-25% savings and trigger occasional verification at full-service properties but rarely at Holiday Inn Express tier."
