"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."

"I've experienced this at the Doubletree Airport TPA. I probably caused it as I spent 100 nights there on our company rate Our corp rate at that location is fantastic. A friend of mine was at Hertz recently and they were checking corporate identification. It may be hit or miss, but I now expect to show my company or government badge. I keep them in my backpack in the first pocket so I can quickly give them to the CSR."

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