What to do with Washington plates after moving to Colorado
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Washington instruction only after the Colorado registration and insurance handoff are safe.
Complete the replacement record
Register the vehicle through the county motor vehicle office within 90 days after becoming a resident.
Bring proof of Colorado-compliant insurance for the vehicle.
Invalidate or return old Washington plates
After the destination registration is active, remove or invalidate the Washington month and year tabs and bend regular plates so they cannot be mistaken for valid plates. Recycle them where accepted or mail or take them to a vehicle licensing office. Washington requires listed personalized, disabled, collector, and other special plates to be returned rather than recycled.
