"The code carries a community-noted ID check status of "Sometimes." Some Hilton properties — particularly in London — began requesting corporate ID when using discount codes in 2022–2023. One user said: "Rule was show a company ID card, or pay the full walkup rate." Another noted they had never once in 10 years been asked for ID before this recent enforcement change. Properties near Seattle Microsoft HQ are flagged as significantly more likely to verify."

"I’m actually due to stay at that Hilton in Newcastle tomorrow night - my employer doesn’t have a corporate code we can use on the app, but there is a specific Hilton.com URL we use for reservations (which is accessible not just from our corporate network) - booked a rate for tomorrow night for around 50% of what the cheapest Honors rate was - I have not had any communication from the hotel requesting proof of eligibility. In my case however I would be able to provide an ID if requested at checkin, which is clearly problematic for you."

"One thing I am curious about is whether the hotel CRM shows the booking channel. Most true corporate travel is booked through something like Concur, AMEX GBT, CWT, etc. If the agent sees the booking come through one of those channels with a person's name on it and then gets a card or photo ID (not corporate ID) from said person, it's a pretty low fraud risk. But if it is a reservation through the hotel's channels using just a typed-in code, then I'd think they would have reason to be more strict in seeking proof of affiliation."
