"Shell's Marriott code SHL appears in FlyerTalk corporate code compilations. Shell is a global energy giant with major US presence in Houston TX. Marriott properties near Houston Energy Corridor routinely handle Shell employees. No specific verification-denial cases were found. The energy sector code pattern tends to be less targeted than tech company codes in current enforcement discussions."

"GAP Inc's Marriott code GAP is listed in corporate code databases. No verification incidents documented in FlyerTalk or Reddit discussions. Clothing retail corporate codes at Marriott receive minimal attention from front desk staff — retail employee IDs are not standardized enough to be reliably verified. US domestic properties rarely verify retail-sector codes."

"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)"
