"ThyssenKrupp's Marriott code TSN is for the German industrial conglomerate (steel, elevators, automotive). German industrial codes follow the European Marriott enforcement pattern: "In Europe, they tend to follow the rule by the book." ThyssenKrupp has significant European properties in Essen/Duisburg (HQ) and US operations in Birmingham AL, Pittsburgh PA, and Calvert AL (steel facilities). FlyerTalk notes German Marriott properties are among the most verification-active. No TSN-specific denial 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 last couple of corporate RFID cards had no company name on them for security purposes. My current company doesn’t do business cards. I use my Bonvoy card for corporate travel to get the points. I’d have to write them an email standing at the check in desk, I guess."
