"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 think the generic 'show corp id' designation means show the company business card. I think a lot of us don't have them or, if we do & we're not going to an office that we'd need to show them, leave them at home. I worked for some F500s that didn't require corp ids with shiny smiling faces on them & others that did; same with company credit cards. All, however, provided biz cards when working for them."
