Notable Facts

Hawaii uniquely encodes the island county of registration in the first letter of the plate: H or Z = Hawaiʻi County, K = Kauaʻi County, M or L = Maui County, all other letters = City and County of Honolulu. This is because Honolulu vehicles are typically discounted versus the outer islands (where there's typically only one dealer per make), so the plate prefix identifies the source.
