The State of Oklahoma has recently adopted an electronic vehicle titling system. This could possibly make it difficult for Delaware Nation Citizens to obtain the titles to their vehicles. When purchasing a vehicle from a dealership, make sure to have the dealership send your vehicle title and paperwork to the Delaware Nation Tag Office (not the state tag office) at P.O. Box 825 Anadarko, OK 73005. If you have a lien on your vehicle and the lien holder has the title to your vehicle, you can request for the lien holder to send your title to our office.
