"FedEx's main IHG code (109207) is documented in the FlyerTalk IHG Rate Codes master thread. The IHG enforcement pattern for FedEx: "Airport Holiday Inns rarely check credentials; InterContinentals in major cities almost always do." FedEx monitors hotel usage volume with IHG — anomalous usage in one business unit could trigger company-side audit. One FlyerTalk user documented IHG refusing to honor a rate without ID and offering to cancel after the cancellation deadline. FedEx employee IDs are physical company badges recognizable to hotel staff."

"Electronic Data Systems (EDS) IHG code (136905) follows the same profile as EDS Marriott — a widely-circulated code from a company now absorbed into HP/DXC Technology. FlyerTalk's IHG Rate Codes thread: "A 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." EDS employee credentials (badges) no longer exist post-HP acquisition, which could complicate verification. IHG InterContinental: likely to ask; Holiday Inn Express: rarely."

"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."
