"Nike's Marriott corporate code NKE is listed on corporate code sharing sites but has no documented FlyerTalk or Reddit thread specifically discussing verification experiences. Nike is headquartered in Beaverton, Oregon; Marriott properties in the Portland metro area may be more familiar with Nike employees. The NKE code is less frequently discussed than Boeing or ExxonMobil codes, suggesting lower community awareness and potentially lower audit frequency. General Marriott enforcement in the US is well under 5%."

"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."

"I've never been asked, but last night I stayed at a SHS I had only stayed at once before and the clerk casually asked "what company are you with" and she was writing out my card. I suspect she was comparing to the rate plan I used for the reservation."
