"Corporate code 41943 is associated with Intel for Hilton Hotels. Verification requirements vary by property, with full-service hotels in major cities more likely to request ID."

"So - to the point - how do I verify my entitlement to this rate? The concept of showing a 'Government ID' is frankly outdated in the UK - aside from the NHS, I don't imagine there are many (any?) government departments (aside perhaps from the military) that have a great big logo/badge advertising that you are infact working with the Government - this is in itself a significant security risk."

"I've been asked about it exactly once. I was doing some personal travel internationally. Hilton actually provides a custom landing page so we can book personal travel using the corporate rate. Anyway, the conversation amounted to: Hilton - "Do you work for Spacely Sprockets?" Me - "Yes." That was it. No other verification was asked for."
