"The code carries a community-noted ID check status of "Sometimes." Some Hilton properties — particularly in London — began requesting corporate ID when using discount codes in 2022–2023. One user said: "Rule was show a company ID card, or pay the full walkup rate." Another noted they had never once in 10 years been asked for ID before this recent enforcement change. Properties near Seattle Microsoft HQ are flagged as significantly more likely to verify."

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