"IBM's Hilton codes (001368083 for International, 0901452 for US) follow the same pattern documented for IBM Marriott. FlyerTalk's definitive IBM hotel thread: "I've used IBM's corporate rate for 14 years at 80-100 nights annually and never once been asked for ID." However, "Newark Airport Marriott religiously asks for ID, requiring a letter from IBM." London Hilton properties have been systematically checking ID since 2022 per documented "London Hiltons requesting corporate ID" thread. IBM is one of the largest corporate travel account holders at Hilton globally."

"- Marriott (CORP): Please be prepared to show proof of eligibility for your rate (such as a membership card, corporate or government identification card, or proof of your age). - Marriott (GOV): Federal Govt issued Visa, MasterCard, American Express, or Federal Govt picture ID (CAC or Common Access Card) - Hilton (CORP): No ID requirements listed - Hilton (GOV): Id-travel orders required at checkin"

"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."
