What to do with Missouri plates after moving to Montana
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Missouri instruction only after the Montana registration and insurance handoff are safe.
Complete the replacement record
Title and register the vehicle through the county treasurer within 60 days after establishing Montana residency.
Carry proof of Montana-compliant insurance while driving. Montana MVD says proof is not required to complete the registration transaction, but coverage remains required for operation.
Destroy, recycle, or return unused Missouri plates
After the destination registration is active, remove the Missouri plates. Missouri says unused or expired plates may be destroyed and recycled where you are, returned to a Missouri license office, or mailed to the Department of Revenue's License Plate Surrender unit. Make an unexpired plate unusable and retain the new registration proof before disposal.
