"Boeing's Marriott corporate code is widely shared online, partly because Boeing has major campuses near Seattle, Chicago, and Charleston — cities where Marriott properties are plentiful. One industry source rates Boeing's code as "Medium Risk," noting verification is more common near Boeing facilities. FlyerTalk documents cases of consultants using codes and being charged $300 (rack) vs. $100 (corp) when failing to produce company ID. Boeing is a defense/aerospace firm with recognizable employee badges."

"I get asked every single time on Government Rates/Per Diem Rates. (Multiple properties per month) I just know to keep my ID right there. Every once in a while they will try to photo copy it and then have to explain that isn’t allowed, otherwise I have no issues with it being validated."

"I occasionally try to get the corporate rate for a company I'm visiting in the area (for sales/consulting). Only once has a front desk clerk asked me to prove my eligibility, and she was satisfied by me giving the name and telephone number of the person I was visiting."
