How do you get your tag back after a car repossesion?

Contact your lender and they can tell you what company has possession of your car. If you contact the repo company, they will let you make an appointment to come in and get any items that had been in the car, as well as the tag. There is generally an inventory fee for this, around $25-50. They may also require you to give them the key to the car. Good luck.
