"Stanford University's Marriott code 349097 is an academic institutional code. University codes at Marriott select-service and full-service properties are rarely scrutinized. Stanford's Silicon Valley presence means nearby Marriott properties are familiar with the code, but academic corporate rates are not high-value enough to trigger enforcement. No verification-denial cases documented in any public forum."

"I have never been asked and I have 51 nights in a Marriott this year using our corp rate."

"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?""
