"Philips' IHG code (953100013) is for the Dutch electronics and healthcare company. IHG enforcement is brand-tier dependent: InterContinental properties in Amsterdam (Philips' HQ city) and other European markets are most likely to verify. Holiday Inn Express properties in the US: essentially never check. Philips has major operations across Europe, North America, and Asia — IHG InterContinental in those regions carries moderate verification risk. FlyerTalk general IHG warning: "They do often ask for ID at full-service properties.""

"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."

"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."
