"AT&T is among the companies with the best Marriott negotiated rates. In the US, I've never been asked to show corporate ID. In Asia and Europe, I've been asked for corporate ID every single time. Since some companies don't put their name on badges for security reasons, the business card route is often tried first and usually accepted."

"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)"
— FlyerTalk_User
"FlyerTalk community specifically notes the MMM code as "the go-to code for the Minneapolis/St. Paul area, described as extremely reliable at local Courtyard and Residence Inn properties, with a low risk rating." One user documented using an IBM rate for 14 years at 80-100+ nights annually and "never once being asked for an ID." Another stayed 500+ nights and was never asked. The 3M code is regionally well-known near 3M's Minnesota HQ."
