What to do with Arizona plates after moving to Montana

The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Arizona instruction only after the Montana registration and insurance handoff are safe.

Montana comes first

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.

Keep proof while Arizona receives the new-state registration notice

After the destination registration is active, keep that registration proof with the Arizona record. Arizona says you do not need to notify MVD because the other state should send notice automatically; until that happens, respond to any Arizona renewal or insurance-verification notice rather than assuming the record is closed.
