What to do with Oregon plates after moving to Montana
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Oregon 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.
Update the Oregon DMV address after the move
After the destination registration is active, update the address on the Oregon DMV record within 30 days, online or by phone. Oregon does not automatically send a new registration card after an address change, so write the new address on the existing card or request a replacement if you need one. Keep the update confirmation with the new registration.
