"No specific FlyerTalk or Reddit threads document AIG code verification incidents. The code follows Marriott's general corporate rate policy. AIG is a large but relatively low-profile financial services firm; its ticker-style code is widely circulated but US properties rarely enforce. International properties (especially Asia and Europe) are more likely to ask. No documented denied-rate cases found specifically for AIG."

"I also use AAA if the corporate is not available. In 10+ years of using AAA I had never been asked to show the card until last month in FL at two different properties. One was a HGI in Palm Beach Gardens and the other a CY in Stuart. Stayed at both since on AAA rate and wasn't asked."

"I have been a Platinum for a few years (which implies I frequent Marriott properties on a regular basis) and up until tonight was NEVER asked for any id to justify a corporate rate or discount (I legitimately use a few corporate rates I am entitled to and AAA rates)"
