To renew your vehicle registration you must "Identify Your Vehicle" by entering the vehicle's license plate or Vehicle Identification Number (VIN).
You must also "Verify Your Identity" by providing your Georgia driver's license number or the Letter I.D. listed on any letter the Department of Revenue has sent you regarding your vehicle.
If you are accessing a vehicle on behalf of a business, i.e. a business owns the vehicle, or do not have a Georgia Driver's License or ID, then you must use a Letter ID.
