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

"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."
