What to do with Hawaii plates after moving to Iowa

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

Iowa comes first

Complete the replacement record

Register the vehicle through the county treasurer within 30 days after establishing Iowa residency, even if the former plates remain valid.

Keep a motor-vehicle liability policy in force that covers you as the operator before driving in Iowa.

Notify the Hawaii county vehicle office within 30 days

After the destination registration is active, write to the Hawaii county finance office that holds the old vehicle record within 30 days of the address change. Include the old and new addresses and keep a copy with the new registration. Ask that county whether it needs any additional step for the old plate or record.
