"Bank One's Marriott code BOB may still exist in Marriott's GDS system following the 2004 acquisition by JPMorgan Chase. JPMorgan has a separate Marriott code (JPM). Legacy acquired-company codes are practically never verified as the hotel has no way to confirm employer identity for a company that no longer exists independently. Risk for legacy codes is negligible."

"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?""

"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."
