"Hilton Deloitte code 601560 circulates widely among Deloitte staff and ex-staff. ID check status is listed as "Sometimes" across multiple tracking sites. Some properties validate eligibility at check-in — it's recommended to keep a company badge, email, or authorization letter handy to avoid being moved back to the Best Available Rate. Large consulting firms like Deloitte have codes hard-coded into Hilton auditing software to trigger ID requests."

"I don't know what will happen if these hotels, car rental companies, or other providers start asking for corporate identification. It seems problematic. Hopefully it will be that only a few locations, of a few brands, are demanding identification and for a specific reason."

"I stayed at the Waldorf Astoria Shanghai and wasn't asked. I got asked at the Hilton-affiliated hotel in Japan. The global policy is to check but implementation differs by property."
