"Oracle's IHG code appears in FlyerTalk's "List of IHG Rate Codes" thread. A FlyerTalk moderator explicitly cautioned: "Unless you're employed by one of those companies, I would avoid using these codes at all. They do often ask for ID." IHG enforcement is tier-dependent: InterContinental and Kimpton properties enforce eligibility most strictly while Holiday Inn Express shows minimal enforcement. One FlyerTalk user documented IHG refusing to honor a rate without ID and offering to cancel the reservation after the cancellation deadline."

"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."

"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."
