"The Hilton BP International code is listed as active with up to 15% discount. No specific FlyerTalk thread or Reddit post documents a verification denial for this code. BP is a globally recognized energy company, but enforcement is reactive (when the hotel is busy or the discount is steep), not proactive. Hilton's verification is reported as inconsistent — roughly 20% of stays for legitimate codes — but no BP-specific incident was documented."

"The GE Hilton code is rated "Sometimes" for ID verification by HotelCorporateCodes.com. FlyerTalk community specifically flagged that GE is known to discipline employees who use corporate hotel rates for personal travel: "GE doesn't allow employees to use their corporate rate for leisure and may fire those who do." On the Hilton side, no documented GE-specific denial incidents found in public forums. GE's footprint across multiple cities means no single geographic concentration triggers heightened hotel verification."

"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."
