"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."

"I get randomly asked for my id if I check in at peak times, if it’s late or super early morning they just let it go. I’ve showed my corporate email on my phone for proof before"

"We just have to book under our corporate rate in Concur regardless of rate. Example in Columbus, OH our 2 preferred properties are Hilton downtown and Hilton Polaris those rooms can be $400+ a night. If I book at the Hyatt House at $199-$225 also part of our general corporate rate off BAR it will tell me I’m out of compliance for not booking our preferred hotels even though they are more. I override this all the time but that’s how it works."
