"Mitsubishi's Hyatt code (11657) follows Hyatt's standard corporate verification pattern. FlyerTalk users report 50% ID check rate across Hyatt stays in Asia, mitigated by "self-printed business cards that worked 100% of the time." Mitsubishi is a major Japanese conglomerate with strong presence at Hyatt properties in Tokyo, Osaka, and Singapore. Park Hyatt Tokyo has specific documentation of requiring "badge, business card, and email confirmation" for corporate rates. Hyatt Place/House properties globally: essentially never check."

The front desk asked him to verify but he couldn't, so we made full payment in the end, no drama."
