"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."

"Harley-Davidson's Hilton code N3846652 is a manufacturing corporate code. No FlyerTalk thread documents HD Hilton verification incidents. Harley-Davidson HQ is in Milwaukee WI — Hilton properties in that market encounter HD employees regularly. Consumer brand manufacturing codes are among the lowest enforcement categories at Hilton. The Hilton verification rate of ~20% applies to urban full-service properties; Harley's travel patterns are concentrated in Midwest and rural/suburban markets where enforcement is minimal."

"I have a client that requires me to use their rate when traveling on their dime. I’ve never been asked to provide ID, but I can simply say that I’m a contractor for said company."
