Registration Renewals
There are several ways to renew your vehicle's registration.
Online
- When renewing a vehicle registration online, a PIN is required to complete your transaction. The PIN can be found on the renewal notice that was sent to you through the US Postal Service.
- If your renewal notice has a "stop" sign on it, the vehicle registration does not qualify for online renewal.
- Half year renewals and apportioned vehicles are not eligible for online renewal.
