"No specific forum reports of verification incidents found for the Disney Hilton code. Disney has one of the largest US workforces, meaning the code is widely distributed and hotels near Disney properties are accustomed to seeing it. Hilton's general 20% verification rate applies. The large and diverse Disney employee base makes stringent verification less practical. Fishbowl discussions about hotel codes focus on consulting firm codes, with Disney not emerging as a frequently discussed verification concern."

"Berkshire Hathaway's Hilton code N0437015 is a holding company code. Berkshire Hathaway itself has very few direct employees (fewer than 30 at HQ) — most employees work for subsidiaries (Geico, BNSF, etc.) that have their own corporate codes. No FlyerTalk thread documents BRK Hilton verification incidents. The holding company code is rarely used since most Berkshire subsidiaries maintain separate travel programs. Minimal enforcement expected."

"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."
