"Ford (alt) Hilton code N0900266 appears to be a secondary Ford Motor Company code. Ford's primary Hilton code is rated Low — no documented verification incidents outside Detroit-area properties. Ford has major HQ in Dearborn MI; Hilton properties in that market are familiar with Ford employees but the general US-wide enforcement rate is very low (~10-20% Hilton average). Secondary codes circulate less widely and face even less scrutiny than primary corporate codes."

"FlyerTalk's dedicated Hilton FedEx thread provides community data: "Hilton is hit or miss about checking for special codes. I have used several codes, all real, and have been asked maybe 20% of the time to show proof." Another user: "I honestly can't remember the last time I made a reservation without some kind of corp code. I have never once been asked to show any sort of ID." FedEx reportedly monitors Hilton usage volume, which could affect contract renewal terms. HotelCorporateCodes.com rates this as "Sometimes.""

"Ford Motor Company's Hilton corporate code is rated "Sometimes" for ID verification on HotelCorporateCodes.com. Ford's HQ in Dearborn means Detroit-area Hilton properties are more likely to verify than properties in other markets. No specific verification incidents documented in public forums outside the Detroit area. General Hilton verification rate applies: approximately 20% chance of being asked for proof, higher at Conrad/Waldorf properties."
