"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."

"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 The concept of showing a 'Government ID' is frankly outdated in the UK - aside from the NHS, I don't imagine there are many (any?)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 would contact your corporate travel. I know some companies have one code for employee business travel and one for employees and their families. Some use just one for all. Shouldn't be too difficult to email to your travel team to get clarification."
