"GE's IHG code is directly mentioned in FlyerTalk: "The GE code brings a Holiday Inn rate down from $114 to $84." A more recent thread warns: "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." GE's documented 70% discount at InterContinental Chicago makes it a high-audit-trigger code at luxury IHG properties. Holiday Inn Express tier: low risk. InterContinental/Kimpton tier: high risk, consistent with the brand-tier pattern across all IHG properties."

"Only once was I asked, by a new room (revenue) manager of a hotel I've used extensively. Explained that the code was provided by my contact at the company, offered to provide his information, and that contractors were included and allowed to use the code. Never had a problem."

"Overall, I have been asked for proof of corporate id or business card especially when using negotiated rates at individual properties. Now at most of these places our company has deeply discounted rates that can be 50% off the BRG and may have last room guarantee too. For example, I have been asked at the Hilton KL, IC Strings Tokyo, IC Jakarta, IC Frankfurt, IC GS Hong Kong, CP Zurich to name just a few. From friends experiences the GH Singapore is also known to ask for proof if some of the quite low negotiated rates are used. Now usually, I was asked once and then it was done and only twice at the Hilton KL, but not all the time on every stay."
