You cannot straightforward throw old license plates in the trash in most states
License plates are the property of your state's Department of Motor Vehicles, not yours, even after you stop using them. Most states require you to return them when you renew, replace, or surrender your vehicle registration. Throwing them away or keeping them can result in fines ranging from $25 to $500 depending on your state, and in some cases may be treated as theft of state property.
The specific rules vary by state. Some states make plate return mandatory; others make it optional but strongly encourage it. A few states have no formal requirement but still ask drivers to return plates to prevent misuse. The safest approach is to contact your state's DMV before disposing of old plates to learn what your state actually requires.
Key Takeaways
- License plates belong to your state government, and most states require you to return them rather than discard them.
- You can return plates at your DMV office, by mail, or sometimes at vehicle registration renewal — the method depends on your state.
- Keeping or throwing away plates without returning them can result in fines of $25 to $500 in states that enforce the rule.
- Some states allow you to keep plates for personal use (like decorative display) only after you formally request permission from the DMV.
How to return plates to your state DMV
The most direct route is to visit your local DMV office in person and hand over the plates. Bring your vehicle registration or ID so staff can document the return. This takes about 10 minutes and creates an when ready record that you complied with the requirement.
Many states also accept plates by mail. You typically place them in a padded envelope, include a note with your name and vehicle information, and send them to the address listed on your state's DMV website. Some states provide a prepaid mailing label or envelope. Check your state DMV's website for the specific mailing address — it is usually different from the main office address.
A third option available in some states is to turn in plates during vehicle registration renewal. If you are renewing online or by mail, you may be able to include the old plates with your paperwork. Call your DMV before you renew to confirm whether this is an option in your state.
States that require plate return versus states that do not
States fall into three categories. The first group — including California, Texas, Florida, New York, and Pennsylvania — explicitly requires drivers to return plates to the DMV. Failure to do so can result in fines or a hold on your driving record.
The second group makes return optional but requests it. These states do not fine you for keeping plates, but they ask you to return them to prevent fraud and theft. Many states in this group will accept plates if you bring them in, even though they do not mandate it.
The third group has no formal requirement. However, even in these states, the plates technically remain state property. Defacing, altering, or selling plates is illegal everywhere. If you want to keep a plate for display purposes, contact your DMV first to ask whether you need written permission.
Why states require plate returns
License plates are tracked by the state for law enforcement and vehicle registration purposes. When you return a plate, the DMV deactivates it in their system so it cannot be used on another vehicle. This prevents someone from using an old plate number to register a stolen car or to evade tolls and traffic cameras.
Plates left in circulation — whether in a junkyard, a thrift store, or someone's garage — create a security gap. A person with access to an old plate and the matching vehicle identification number can sometimes register a vehicle without proper ownership documentation. Requiring return closes this loophole.
Keeping plates also creates a record problem for you. If a vehicle registered to that plate is involved in a crime or traffic violation after you sold or junked the car, you may be contacted by police. Returning the plate and getting written confirmation from the DMV protects you by creating a clear handoff date.
What happens if you keep or discard plates without returning them
In states with mandatory return rules, keeping plates can result in a fine. The amount varies: California fines up to $250, some states impose $50 to $100 fines, and a few states can fine up to $500. You may also face a hold on your driving record or registration renewal until you return the plates.
If you throw plates in the trash and they are later found and used fraudulently, you could be questioned by law enforcement. While you would likely not face criminal charges if you can show you disposed of them unintentionally, the investigation and paperwork are time-consuming. Having a DMV receipt showing you returned them avoids this entirely.
In states without mandatory return rules, there is no fine for keeping plates, but there is still risk. If you keep a plate and later sell the vehicle, the new owner may not know the plate is still registered to you. If they use it on another vehicle or if the plate is stolen from your property, you remain the registered owner in the DMV system until you formally return it.
Keeping plates for display or collection
Many people want to keep old plates as souvenirs or for decorative display — particularly plates from vehicles with sentimental value. Some states allow this, but the process varies. A few states let you keep plates without asking. Others require you to request written permission from the DMV before you keep them.
If you want to keep a plate, contact your state DMV and ask whether you need a retention permit or written approval. Some states will issue this for free; others charge a small fee. Get the approval in writing so you have documentation if you are ever questioned about why you have an old plate.
If you are keeping a plate for display, do not use it on a vehicle. Displaying an old plate on a car you are driving is illegal in all states, even if you own both the plate and the vehicle. The plate must be inactive in the DMV system.
What to do if you already threw plates away
If you discarded plates before learning about the return requirement, contact your state DMV and explain what happened. In most cases, the DMV will not pursue a fine if you can show good faith — that you did not know about the requirement and are now complying. Bring your vehicle registration and ID to the DMV office and ask them to note in your file that you are aware of the requirement going forward.
If you are concerned about plates you discarded years ago, the risk is low. The DMV is primarily focused on preventing future misuse, not punishing drivers for past disposal. However, if you are selling a vehicle or renewing your registration soon, mention it to the DMV staff so there is no confusion in your records.
Frequently Asked Questions
Can I recycle old license plates?
Most recycling centers do not accept license plates because they contain reflective coatings and metal that require special handling. Your DMV is the proper place to take them. Some DMV offices recycle plates after they are returned, but that is the state's responsibility, not yours.
What if I lost my old plates and cannot find them?
Contact your DMV and report them lost. Bring your vehicle registration and ID. The DMV will note in their system that the plates are no longer in your possession and will deactivate them. You will not be fined for losing them if you report the loss.
Do I need to return plates if I sell my car to a dealer?
When you sell a car to a dealer, the dealer typically handles the registration transfer and plate return. However, check your state's rules — some states require the seller to return plates before the sale is final. Ask the dealer what they need from you before you hand over the keys.
Can I keep my old plates if I buy a new car?
In most states, you cannot transfer old plates to a new vehicle. Each vehicle gets a new plate when you register it. You must return the old plate from your previous vehicle. Some states allow you to request the same number on a new plate, but that is different from keeping the physical old plate.
What if my state says plate return is optional but I want to return them anyway?
You can return plates to the DMV in any state, even if return is not required. Bring them to your local DMV office or mail them according to the instructions on your state's website. Getting a receipt or written confirmation protects you by creating a record of the return.
