"I used to China often for work and book directly. I’ve never been asked, if you have a sticker or they can see something with the company logo they assume you work there. I’ve only been asked in Korea and was a hot mess until a manager stepped in."

"AT&T is among the companies with the best Marriott negotiated rates. In the US, I've never been asked to show corporate ID. In Asia and Europe, I've been asked for corporate ID every single time. Since some companies don't put their name on badges for security reasons, the business card route is often tried first and usually accepted."

"HotelCorporateCodes.com rates the Marriott DIS code as "Sometimes" for ID verification. No dedicated forum thread found specifically discussing Disney corporate code verification incidents. Disney has 140,000+ US employees and the code is widely circulated. One FlyerTalk user noted that a retired employee who disclosed their retired status was never asked for ID, suggesting properties prioritize rate code volume over strict verification. FL Marriott properties near Orlando HQ are most familiar with the code."
