"JC Penney's Marriott code JCP is a retail corporate code. No FlyerTalk or Reddit thread discusses JCP verification incidents. Retail corporate codes at Marriott are among the lowest-scrutiny categories — JC Penney employees travel primarily for store visits to suburban/mall-adjacent markets where Marriott select-service properties dominate. These property types essentially never verify corporate codes. JC Penney's financial difficulties (multiple bankruptcies) mean active corporate travel has declined."

"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)"

"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."
