What to do with Mississippi plates after moving to Idaho
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Mississippi instruction only after the Idaho registration and insurance handoff are safe.
Complete the replacement record
Title and register the vehicle through the county assessor's motor vehicle office within 30 days after moving to Idaho.
Use coverage from a company licensed to do business in Idaho that meets the state's minimum liability limits.
Skip an ineligible Mississippi move-out refund
After the destination registration is active, contact the Mississippi county Tax Collector to update the address tied to the old tag. Do not count on recovering the unused registration: Mississippi says the credit cannot be used after an out-of-state move and no refund is issued. Keep the new registration and the address-update record together.
