Alaska License Plates
Month and year renewal date stickers still used in 2026 despite their elimination being considered in 2023. Z sticker on Alaska license plate signifies permanent registration.
Alaska is not a member of the International Registration Plan (IRP) and thus does not issue apportioned plates. Heavy trucks, trailers and buses based elsewhere but using Alaska roads must also register their vehicles separately in Alaska, resulting in some interesting plate observations on those vehicles.
See 15q.net for more details on Alaska passenger plates since 1969.
