"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 stayed at the Waldorf Astoria Shanghai and wasn't asked. I got asked at the Hilton-affiliated hotel in Japan. The global policy is to check but implementation differs by property."

"I've been asked about it exactly once. I was doing some personal travel internationally. Hilton actually provides a custom landing page so we can book personal travel using the corporate rate. Anyway, the conversation amounted to: Hilton - "Do you work for Spacely Sprockets?" Me - "Yes." That was it. No other verification was asked for."
