What to do with Idaho plates after moving to Alaska
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Idaho instruction only after the Alaska registration and insurance handoff are safe.
Complete the replacement record
Apply for Alaska registration within 10 days after entering the state or taking an Alaska job when you intend to establish residency.
Keep coverage in force through the move and confirm that the policy satisfies Alaska's requirements before operating the Alaska-registered vehicle.
Cancel the Idaho plate record before dropping its insurance support
After the destination registration is active, submit Idaho's ITD 3438 License Plate Cancellation Request with the moved-out-of-state reason and choose whether to cancel the plate, registration, or both. Keep the submitted form and delivery confirmation before ending the policy that supported the Idaho record.
