"hotelcorporatecodes.com flags CapGemini N0990552 as "Sometimes" ID check required. Consulting-sector codes cluster in the "Sometimes" tier because the per-night discount is meaningful enough for high-demand properties to query it. The FlyerTalk London thread (November 2023) documented that UK Hilton properties have broadly moved to requesting corporate ID on discounted codes, which directly affects large consulting firms with London footprints like Capgemini."

"I completely understand that IDs aren't a big thing. I straddle both private and public and have ID from both sides. I have also held an ID card from two global banks and sure enough the bank name is not on the ID. I always wondered why, so thank you for explaining that."

"Thanks for the prompt response. It's odd - the difference in the rate I booked and the next cheapest Hhonors rate was only £20! It just doesn't seem worth the effort of protecting even if I had, somehow acquired the code when I shouldn't have. Do please report back on your stay - will be interesting to note if you are also asked for some ID."
