"Not a code per se, but I've booked the Intercontinental Grand Stanford in Hong Kong and the Intercontinental Tokyo Strings recently using the Government rate. Both places wanted to see my govt ID."

"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."

"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."
