"GEE is rated "Rarely" for ID verification by HotelCorporateCodes.com, one of the lower-risk Marriott corporate codes. However, a notable FlyerTalk warning exists: "Companies like GE don't push their employees to use their corporate rate for leisure and FIRE them if they do." While hotel-side verification risk is low, GE reportedly monitors usage and has disciplined employees for personal travel misuse. GE's corporate policy appears stricter than hotel enforcement."

"I work for a company that is partially owned by a Fortune 100 company and we have their corporate rate code linked to our travel website, (although it is one of the ones that is very easy to figure out). In 4+ years I've never been asked for any ID, although a few times a year I get the question of "what company are you with?""

"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."
