"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.""

"A former Siemens employee posting on FlyerTalk noted: "When checking in as a group of Siemens employees, we were never asked for ID. However, when traveling alone, front desk staff often asked for some form of ID." IHG enforcement is highly fragmented across its franchise network. Siemens's code falls into the mid-tier corporate bucket. At InterContinental/Kimpton properties, verification is near-certain; at Holiday Inn Express, essentially never. IHG's 2018 T&C update explicitly added unauthorized corporate rate use as grounds for account closure."

"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."
