"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."

"I had the same experience with the IBM corporate rate. When I went to IBM sites to install machines they always said stay at one of these hotels and tell them you need the IBM rate. Always worked and saved a lot of money and I always got full credit with the hotels frequent stay program."

"UPS' IHG code (108146) is for one of the world's largest package delivery companies. UPS has 500,000+ global employees and major hub in Louisville KY. IHG enforcement: Holiday Inn Express near UPS distribution centers (Louisville, Atlanta, Dallas, Newark) rarely checks; IHG InterContinental/Kimpton properties in business centers are more likely to verify. UPS employee IDs are physical company-issued photo badges recognizable to hotel staff. No specific UPS IHG denial incident documented in FlyerTalk."
