"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 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."

"FedEx Ground is one of several FedEx business unit codes in IHG's GDS system. The general FedEx IHG pattern documented on FlyerTalk: IHG has been "very careful" in recent years about verifying codes at full-service brands. FedEx Ground staff IDs are company-standard. Properties near FedEx Ground hubs (Indianapolis, Memphis) are more familiar with FedEx employee badges and may request them. Holiday Inn Express near distribution centers: essentially never check."
