"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."

"Hilton and Marriott Japan actually do check to ensure you qualify for any special rates. They also scan your passport too just FYI. It's not the wild west out here. Be prepared to prove you are eligible for the code or have the rate switched if you can't. Hope you got a business card from your company."

"I have been asked for Employment ID for the first time in London this year too, and multiple times so. Not had that in years."
