"Hyatt is quite strict about checking identification, especially in their hotels in Asia and Europe. Hotel in question may require employee verification."

"I used a code at the Ritz in Tokyo. When I was asked for my Google code, I just straight up said charge me regular rate. The front desk said okay, but when I checked out they never updated it. I was at an AVIS in LAX a few weeks ago, when they asked for my Palantir proof; I just said charge me the regular rate. The front person tried to charge me an outrageous rate, so I just walked off and booked at National. My advice would be to try and book where they have skip the desk options."

"International locations will require a passport as identification when you check-in to confirm idenity and for other govt and immigration reasons. It is not b/c you used a corporate id code. Also, every international hotel I have stayed in at Hyatt has asked for a business card. This is so they can update there records for futrue stays and it is easier for them to read the business card. They are not looking for you to show them an employee id badge. I have used and continue to use various corporate codes to get the best discount, I generally give them my business card so their records are clear, but have never had an issue."
