"Lowe's Marriott code LOW is a home improvement retail code. No FlyerTalk thread discusses Lowe's verification incidents. Lowe's HQ is in Mooresville NC with regional distribution nationally. Retail corporate codes at Marriott select-service and full-service properties yield near-zero verification frequency. The massive retail workforce (250,000+ US employees) makes ID verification impractical. No specific LOW denial incident documented in public forums."

"I used to China often for work and book directly. I’ve never been asked, if you have a sticker or they can see something with the company logo they assume you work there. I’ve only been asked in Korea and was a hot mess until a manager stepped in."

"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."
