"General Electric's IHG code (102806) reflects GE's massive global travel volume. FlyerTalk specifically documented IHG escalating GE code enforcement: "In the past two years, IHG has been very careful in checking on people using IBM and GE corporate rates. Not only corporate ID is required, also an email from IBM or GE to confirm staff identity in extreme cases." At Holiday Inn Express tier: essentially no enforcement. At InterContinental tier: near-certain verification and potential email confirmation. GE's 70% discounts at some InterContinentals trigger automatic audit flags."

"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."
