"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 have used my corporate code multiple times and never once have I been asked for an ID."

"I've been asked about it exactly once. I was doing some personal travel internationally. Hilton actually provides a custom landing page so we can book personal travel using the corporate rate. Anyway, the conversation amounted to: Hilton - "Do you work for Spacely Sprockets?" Me - "Yes." That was it. No other verification was asked for."
