"Prudential Financial's Marriott code PRU is a financial services code. Finance codes in major business centers (NYC, Newark NJ where Prudential is HQ'd) face more scrutiny. FlyerTalk's finance sector enforcement thread: "NYC-area full-service Marriotts — the W, the Westin, the Marquis — have all been reported in individual accounts as asking for corporate ID." Prudential's massive Newark/NYC presence means front desk staff are familiar with Prudential employee badges. No PRU-specific denial documented; pattern-based Medium risk."

"I have been asked to show some proof couple of times. I normally show my corp id but credit card with employers name on it has worked, too. As would probably just showing my laptop with employer e-mail account or whatever. My impression has been they are happy with just about anything that proves I'm working for the company whose rate I use and why wouldn't they."

"I am very rarely asked to prove my eligibility for a rate...but they have every right to ask and if you can't produce it, you will be re-rated to the current rate, which is often even higher and there is no guarantee points rooms will be available. Doing online check in rarely helps this as most properties don't actually do online anyway - especially to people who are not returning guests to the property or elite. You are taking a gamble. One that is likely to be fine. But understand you are intentionally breaking the terms of the bonvoy program and if someone really cared, there can be consequences."
