"hotelcorporatecodes.com lists MCD (McDonald's) explicitly with verification status "✅ Rarely" — the lowest verification designation. Regional scope is North America. McDonald's corporate travel tends to concentrate in suburban/airport corridors near Oak Brook IL HQ and regional offices — property types (Courtyard, Residence Inn, Marriott) in these corridors have the lowest enforcement rates on FlyerTalk. No specific FlyerTalk thread found discussing MCD code challenges. The "Rarely" rating aligns with the general pattern that non-financial, non-consulting consumer-brand codes at non-luxury US properties face minimal scrutiny."

"I work for a company that is partially owned by a Fortune 100 company and we have their corporate rate code linked to our travel website, (although it is one of the ones that is very easy to figure out). In 4+ years I've never been asked for any ID, although a few times a year I get the question of "what company are you with?""

"I think the last time I was asked for proof was in a JW Marriott in Beijing. I have never been asked in the US or Europe. Without a business card or ID, you may have an issue. Maybe you can contact the hotels in advance to see what info they need. I don’t remember if LinkedIn is available in China so I would talk to your Corp Travel team to see what they can do. Good news is that hotels are so much cheaper in China compared to ROW right now. ."
