"Oracle Taiwan's Hyatt code (52730) shares the same risk profile as Oracle's other Hyatt codes. FlyerTalk's "Hyatt Discount Codes" thread specifically documents: "Andaz Tokyo asked for badge, business card and email" and "Park Hyatt Sydney liaised directly with my company's travel desk." Oracle codes at Hyatt are particularly high risk because: (1) Oracle has a documented close relationship with Marriott/hotel brands; (2) Taiwan Hyatt properties enforce verification with near 100% frequency. Combined with the general Oracle + Asia Hyatt pattern, this code is rated High risk."

"I’ve stayed at the HR Tokyo four times on leisure travel using the Deloitte corporate code. I believe they have asked for my badge each time, which I have shown to them and it has not been an issue. They have never asked if I was traveling for business, and I have had someone with me each time (either my partner or mom)."

"Yup, Asia is very strict; I don't think I've never not been asked for either a business card, an ID badge, or a corporate email to make sure that it doesn't bounce back. They often photocopy it or take a photo and send it to their manager and wait until they get an OK before they check me in. There have also been hotels that have emailed me ahead of time, saying that if I didn't provide ID via email, they would update my reservation to the rack rate. North America has been a bit more lax. The higher the discount, the higher the chances of being asked, in my experience."
