"A Fishbowl post titled "Anyone ever use another company's corporate discount code for Marriott? XOM Exxon code is showing a significant discount" directly references this code, confirming community awareness. FlyerTalk confirms Marriott is usually strict about corporate codes: "Consultants who tried to use a former company's code were required to produce a valid company ID. Since they couldn't, they were charged the full going rate of $300 instead of the corp rate of around $100." XOM is a ticker-style code with high profile."

"I have stayed 100s of times with various corporate rates (including Japan) and the only hotel that has asked is W hotels. Even then they didn’t push much. I have been a consultant for 20 years and many clients require you to use their rates when they are paying the bill. The hotel doesn’t have an up to date list of every employee that works for a company globally. The woman at the W said “I don’t really care, just show me anything on your phone that says your name and that company. You can type an email now “."

"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."
