"UBS is explicitly discussed on FlyerTalk in the "Corporate ID required???" thread. One user: "Of the numerous Marriotts I've used my corporate code at in the US and Asia, I was only asked once — at the SF Marriott, because that particular hotel has seen a number of people abusing the corporate discount policy." Another: "Asia is the one place where I have been asked to show ID." A commenter noted: "if Marriott was really concerned about abuse, maybe they should have picked something other than stock ticker symbols as the prevalent corp code" — directly referencing UBS-style codes. hotelcorporatecodes.com: "⚠️ Sometimes," 10-15% discount. Financial services codes at full-service urban Marriotts in Europe (London, Zurich) carry meaningfully higher risk."

"I work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."

"We know what the various Deloitte, EY, PwC, Google, Meta, etc badges look like. If you work for the company, it’s not a problem to verify that you work there. We do this for the random people that say they work for Deloitte, when in reality, they just refill the vending machine at a Deloitte office."
