Discontinued plates are plates that are no longer issued by the DMV. These plates are still valid for vehicle registration except for the Bighorn Sheep plate.
The original owner of the plate must keep it continually registered to a vehicle and it cannot be expired for more than 30 days. The plate may be transferred to another vehicle but not to another person.
Most plates with a discontinue date of December 31 failed to maintain the minimum number of active registrations required for charitable plates.
