Where do I get a car tag / license plate?

Car and truck tags are issued by the Tax Collector within the Sheriff's office. You have 7 working days from the date of purchase to register your vehicle. New residents moving from another state have 30 days to obtain a new plate.  It is helpful to bring your automobile registration and/or title.  New residents from another parish in Louisiana can wait until their next renewal to change plates. Tags are usually valid for a period of one year from the date they are issued.
