"McKesson's Hilton code N9890367 is for the pharmaceutical distribution giant. McKesson HQ is in Irving TX (relocated from San Francisco). Healthcare sector codes at Hilton carry moderate enforcement risk — similar to pharma company codes. Hilton's London thread documented systematic enforcement for corporate codes; McKesson has UK operations. US domestic Hilton: 20% general verification rate. No McKesson-specific denial documented at Hilton, but corporate contracts with major pharma distributors are closely monitored."

"I have used my corporate code multiple times and never once have I been asked for an 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 The concept of showing a 'Government ID' is frankly outdated in the UK - aside from the NHS, I don't imagine there are many (any?)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."
