"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."

"This Deloitte code circulates widely among current and former staff. IHG auditing materials note that large firms like Deloitte and IBM have codes hard-coded into IHG's auditing software to trigger a request for ID. The "Stop at Desk" flag has been observed: certain high-value codes block issuance of a Digital Key until physical ID is presented at the front desk."

"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."
