"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 use MY job's corporate code when booking personal travel. Most companies have a list of which hotels they contract with also allow personal bookings. If you're improperly using a corporate code, the hotel can cancel your booking or change your rate at check in."

"We have a personal travel option in Concur and can also use the corporate travel agency for personal travel. Rates usually match between Concur and booking direct with the code but vary from time to time. The PH Sydney dates I looked at were $1,200 (BAR), $700 (corp code), $500 (Concur)."
