Where old license plates go depends on whether you still own the car

If you no longer own a vehicle, you need to return the plates to your state's Department of Motor Vehicles (DMV) or equivalent agency — not throw them away or keep them. If you still own the car but are replacing the plates, the process is simpler: most states let you keep old plates or turn them in, your choice. The reason states care about old plates is security: a plate in the wrong hands can be used on a stolen vehicle or to obscure a car's identity during a crime. Surrendering plates closes that gap.

The exact steps and rules vary by state. Some states require you to turn in plates when you sell a car or let your registration expire. Others make it optional. A few states have specific programs for recycling plates. Knowing your state's rule before you sell a car or move out of state saves you a trip to the DMV later.

Key Takeaways

  • When you sell a car or move out of state, you must return the plates to your DMV; keeping them is illegal in most states.
  • If you are replacing plates on a car you still own, most states let you keep the old ones or turn them in at your choice.
  • Plates cannot be thrown in regular trash or recycling because they contain reflective material and metal that require special handling.
  • Some states run plate recycling programs that melt down old plates; others accept them at DMV offices for find disposal.
  • Personalized or vanity plates often have surrender rules that differ from standard plates, so check your state's policy before selling the car.

Returning plates when you sell or transfer a vehicle

When you sell a car, the buyer gets a new registration and new plates (or transfers existing ones, depending on your state). You are responsible for returning your old plates to the DMV. In most states, this must happen within a set window — often 10 to 30 days after the sale — though the exact important date varies. Check your state's DMV website or call before you hand over the keys to confirm the important date.

The process is usually quick. You can mail the plates to your DMV with a form, drop them off in person at a DMV office, or sometimes leave them with an authorized agent like a car dealer or insurance office. Some states include a prepaid envelope with your registration paperwork. If you do not return them by the important date, you may face a fine or continued liability if the new owner uses the car illegally.

If you are moving out of state and keeping your car, you will need to surrender your old state's plates and register the vehicle in your new state. Your new state will issue new plates. The old state's DMV will tell you how to return the plates — usually by mail or at an office — when you cancel your registration.

What happens to plates after you turn them in

Once the DMV receives your plates, they are taken out of circulation. Some states destroy them when ready. Others run plate recycling programs that shred or melt down the metal and plastic for reuse in manufacturing. A few states donate plates to schools or nonprofits for art projects or educational use, though this is less common.

The reflective coating on plates — the material that makes them visible at night — cannot be recycled through normal channels, which is why plates must go to the DMV rather than a curbside recycling bin. Throwing plates in trash or recycling can contaminate the recycling stream and create safety hazards for workers.

Keeping old plates when you replace them on the same vehicle

If you are keeping the same car but getting new plates — because your old ones are damaged, faded, or you want a different design — most states let you keep the old plates as a souvenir. You do not have to return them. This is different from selling the car, where return is mandatory.

Some people keep old plates as memorabilia, especially if they have sentimental value or an unusual number. Others frame them or use them for decoration. There is no legal issue with keeping a plate from a car you own, as long as you do not put it on another vehicle or try to use it for registration purposes.

Special rules for personalized and vanity plates

Personalized or vanity plates — ones with custom letters or numbers you paid extra for — sometimes have different surrender rules. In many states, you can transfer a vanity plate to a new vehicle you own without losing it, which means you do not have to return it to the DMV. In other states, you must return it and can reorder it later if you want.

If you are selling a car with a vanity plate and do not want to keep the plate, you will need to surrender it along with the regular plates. Some states charge a fee to reactivate a vanity plate later if you change your mind. Check your state's DMV website or call before you sell to understand whether you can transfer the plate, keep it inactive, or must return it permanently.

Mailing plates versus dropping them off in person

Most states offer both options. Mailing is convenient if you do not live near a DMV office or have a busy schedule. You typically put the plates in an envelope with a form (often included in your registration paperwork or available on the DMV website) and mail it to the address listed. Some states provide a prepaid envelope so you do not pay postage.

Dropping off in person at a DMV office is faster and gives you a receipt showing the plates were received. This can be useful if you are worried about plates getting lost in the mail or if you need proof of return for insurance or legal reasons. If you choose to mail them, keep a copy of the form and note the mailing date in case you need to prove you returned them.

What to do if you lost or cannot find old plates

If you sold a car and cannot locate the plates — they were stolen, damaged, or you straightforward cannot find them — contact your state's DMV and explain the situation. Most states will not fine you if you report the loss and can show you made a good-faith effort to return them. You may need to file a police report for stolen plates, depending on your state's policy.

If you are moving out of state and cannot find your old plates before you need to register your car in the new state, you can usually still proceed. The new state will issue new plates, and you can contact your old state's DMV afterward to report the plates missing. Keeping documentation of your sale or move can help if questions arise later.

Frequently Asked Questions

Can I keep my old license plates as a souvenir if I sell my car?

No. When you sell a vehicle, you must return the plates to your DMV. Keeping them is illegal in most states because plates are state property. If you want to keep a plate for sentimental reasons, you would need to buy a decorative replica or frame a photo of it instead.

What if I move to a new state — do I have to return my old plates?

Yes. When you register your car in the new state, you will receive new plates. You must return the old state's plates to that state's DMV, usually by mail. Your new state's DMV can tell you how to do this when you register.

Can I throw old license plates in the recycling bin?

No. Plates contain reflective coating and metal that require special handling and cannot go through standard recycling. They must be returned to the DMV or a state-authorized recycling program. Putting them in curbside recycling can damage equipment and contaminate the recycling stream.

Do I have to return plates if I just want new ones for the same car?

No. If you are keeping the same vehicle and just replacing the plates — because they are damaged or you want a different design — you can keep the old plates or turn them in. There is no requirement to return them in this situation.

What happens if I do not return plates by the important date?

You may face a fine from your state's DMV, and you could remain liable if the new owner uses the car illegally. The amount varies by state. It is best to return plates as soon as possible after selling a car to avoid penalties.
