"Not a code per se, but I've booked the Intercontinental Grand Stanford in Hong Kong and the Intercontinental Tokyo Strings recently using the Government rate. Both places wanted to see my govt ID."

"FedEx Supply Chain Services (100172336) and FedEx Trade Networks (970001266) are IHG codes for FedEx supply chain and trade services divisions. The same FedEx IHG enforcement pattern applies: tier-dependent verification at IHG properties. FedEx Supply Chain has major facilities in Memphis, Pittsburgh, and across the US Southeast — IHG Holiday Inn properties near those facilities are familiar with FedEx employee badges. FedEx Trade Networks focuses on international freight logistics; international IHG InterContinental properties carry higher verification risk."

"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."
