"FlyerTalk's Hyatt corporate codes thread identifies code 90010 as resolving to Li & Fung Trading Ltd in Hyatt's system, not Oracle directly. This creates a mismatch risk: if a guest claims Oracle employment but the code resolves to a different company in the system, a suspicious front desk agent could escalate. Park Hyatt Sydney has been documented liaising directly with company travel desks, and Andaz Tokyo has required badge, business card, and email confirmation."

"I still see a problem for those that don't have a badge and not all employees do"

"I really don't think you should be worried. I have never been asked for ID at any hotel including the PHT. In fact, all the front desk person knows is that you are using some type of corporate discount. You are right, you could have any of a number of connections to the company, vendor, contractor, applicant, spouse of employee or applicant, salesperson, client and the list goes on."
