"Morgan Stanley's Marriott code MOS is listed alongside Goldman Sachs and UBS codes in FlyerTalk's compilation of financial institution corporate codes. The SF Marriott and midtown Manhattan Marriotts were specifically cited in enforcement threads as properties that "cracked down on corporate code abuse." For financial sector codes, the discount threshold triggers audit flags — if Morgan Stanley's rate is 20%+ below BAR, full-service properties are more likely to verify. US domestic verification: 10-20% at urban full-service; Europe/Asia: meaningfully higher. No MOS-specific denial incident documented."

"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."

"My employer does not have a corporate rate but when I'm consulting for a company that does, I use theirs. I've only been challenged for identification once. In that one situation I explained the consulting arrangement, and the desk clerk accepted it without a badge or business card (neither of which I had anyway)."
