"McKinsey codes at luxury Hilton brands (Conrad, Waldorf Astoria) carry higher verification risk. One Fishbowl user was asked at a Westin SF for firm ID, resolved by offering work email verification. Hilton verification is hit-or-miss, roughly 20% of the time across legitimate corporate codes. Code is flagged in industry databases. Properties near McKinsey offices show heightened scrutiny."

"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."

"Thanks for the prompt response. It's odd - the difference in the rate I booked and the next cheapest Hhonors rate was only £20! It just doesn't seem worth the effort of protecting even if I had, somehow acquired the code when I shouldn't have. Do please report back on your stay - will be interesting to note if you are also asked for some ID."
