"FlyerTalk's landmark thread "London Hiltons now requesting corporate ID if using codes" (2022-2023): "Just a word to the wise. London Hilton chains are now requesting corporate ID if you are using the discount codes." A second user confirmed: "I have been asked for Employment ID for the first time in London this year too, and multiple times so." The stated policy: "show a company ID card, or pay the full walk-up rate." Community-wide Hilton estimate: "hit or miss, about 20% of the time." UK/Europe properties have meaningfully tightened since 2022 — P&G's Hilton code N0000537, as a globally-used corporate code, is precisely the type flagged in London and other European cities."

"My point is only that this does happen and it can be problematic for those that work for a company that has great negotiated rates and the provider requires identification."

"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."
