"Pepsi 20937 is confirmed in Hyatt code directories. FlyerTalk user Colin stated: "US & MX hotels never check, in my experience" for consumer/FMCG brand codes. Pepsi is headquartered in Purchase NY with heavy Hyatt usage at mid-tier domestic properties (Hyatt Place, Hyatt House) — the exact brands identified as having the rarest verification rates. Consumer packaged-goods brands present the same ambiguous franchise/bottler affiliation challenge as McDonald's, making challenges impractical."
