What to do with Delaware plates after moving to Mississippi
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Delaware instruction only after the Mississippi registration and insurance handoff are safe.
Complete the replacement record
Apply through the county Tax Collector within 30 days after moving while the prior registration remains valid. Mississippi publishes a $250 penalty in addition to standard late-registration penalties for missing the new-resident deadline.
Maintain Mississippi liability coverage and keep the insurance card in the vehicle. The state notes that proof is required for operation even though registration offices do not enforce it as a filing prerequisite.
Surrender active Delaware plates before canceling insurance
After the destination registration is active, surrender any Delaware plate with active registration time to DMV and keep delivery or counter proof. Only then cancel the Delaware policy.
