"Siemens has multiple Hilton codes (D323009803, 323009803, N0079268, 302844100) reflecting different business units and tiers. hotelcorporatecodes.com notes Siemens in the "Sometimes" category at Hilton. UK/Europe Hilton properties have increased enforcement since 2022 — Siemens has major Munich HQ operations where Hilton properties regularly encounter Siemens employees. FlyerTalk's London Hilton enforcement thread documented: "show a company ID card, or pay the full walk-up rate." German Marriott properties near Siemens facilities: medium-high risk."

"I know that previously the Hertz IBM rate was always fixed in the mid $30s for a full size vehicle with last car availability. A minivan was $175/week in Orlando even during President's week when the going rate was about $1,200. This is probably why Hertz and at least Avis has been more strict. I have found Marriott to be very strict, especially at key locations, when it comes to the government rate. Marriott wants travel orders, a government ID, and/or a government credit card. I found Hilton to be less strict for those government rates."

"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."
