"UBS' Hyatt code (42366) is documented in FlyerTalk's Hyatt corporate code community. Unlike the now-defunct Credit Suisse Hyatt code (12624, rated High due to specific Tokyo staff alert), UBS Hyatt is UBS's own direct corporate code. FlyerTalk's Hyatt verification pattern: Park Hyatt Zurich and Park Hyatt Zurich are among the most enforcement-active European Hyatt properties for financial institution codes. FlyerTalk general: "50% check rate across 10 countries, primarily at Park Hyatt." Self-printed business cards work "100% of the time" per one user."

"I mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."

"I don’t really know how they truly enforce this. A lot of companies don’t even put the company name or brand on ID cards anymore due to security concerns (if you find a card on the ground it’s a lot harder to know where to use it). In 20 years of traveling for work I’ve only been asked for a form of ID one time, which was in Germany, and sending the front desk agent an email from my corporate email address took care of their concern."
