"HotelCorporateCodes.com rates the Wells Fargo Hilton code as "Sometimes" for ID verification. Hilton verification is inconsistent — approximately 20% of stays trigger ID checks for corporate codes. Wells Fargo's massive presence in San Francisco means properties there are familiar with the code and its legitimate users. No specific reports of being denied or charged full rate. Business card or work email typically resolves verification requests."

"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."
