"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 actually used to work for the Park Hyatt Sydney several years ago, in sales and marketing. Every year corporate rates are negotiated based on the number of room nights from the previous year. I can assure you that the abuse of these codes will not go unnoticed. While a chainwide code may apply, it wouldn't be difficult for IBM to see that rates were being used at a property they may not utilise, such as the Park Hyatt Sydney due to the high average room rate, and realise that the code was being abused. They will also notice a significant spike in room nights booked."

"We are pleased to note you have a future reservation on xxxxxx, 2010 made through hyatt.com. I do kindly ask that you bring your valid working ID in order for us to be able to confirm the corporate rate at time of check-in which will be cross referenced with the company. Unfortunately of late we have been experiencing misuse of some of our corporate rates, with your company a target and we have had to implement tighter controls in this regard."
