"A FlyerTalk thread titled "London Hiltons now requesting corporate ID if using codes" (November 2023) documents: "Rule was show a company ID card, or pay the full walkup rate — quite a shock if unexpected." Users report that in 10 years of stays, they had never been asked until 2022-2023, suggesting a recent policy shift. The crackdown is attributed to deep corporate discounts (50%+ off rack rate) at Fortune 500 codes — AT&T as a major carrier falls into this high-value discount tier."

"My hotel doesn't check corporate ID, but we do check drivers license like any other hotel to make sure you are the correct person it was booked for,"

"I believe that the major companies that receive significantly discounted rates, are those that typically issue a corporate card and/or a picture ID to their employees. The US federal government and even the State government certainly do issue ID to their employees along with corporate charge cards to their travelers. I don't think that it's an issue with a 10% general discount such as you would get with AAA. it's the corporate discounts (for typically Fortune 500 companies and the government), where the rates can be 50% or more of rack rate. The negotiated rates."
