DMV tags are the metal or plastic plates attached to your vehicle that display your registration number and state

A DMV tag (also called a license plate or registration plate) is the official identifier your state assigns to your vehicle. It shows a unique combination of letters and numbers that links your car, truck, or motorcycle to your registration record at the Department of Motor Vehicles. When a police officer runs your plate, they see your name, address, vehicle details, and whether your registration is current.

Every vehicle driven on public roads must display valid tags. Your state issues them when you register a vehicle for the first time, and you renew them periodically — usually every one to three years depending on your state's rules. Tags serve as proof that you have paid registration fees and that your vehicle meets safety and emissions standards.

Tags are not optional, decorative, or something you can ignore. Driving without valid tags, with expired tags, or with obscured tags is a traffic violation that can result in a fine, a ticket, or both. Some states will also suspend your registration if you do not renew on time.

Key Takeaways

  • DMV tags are metal or plastic plates issued by your state that display your vehicle's unique registration number and must be displayed on the front and rear of your vehicle.
  • Tags expire on a schedule set by your state — typically every one to three years — and you must renew them before the expiration date to keep your registration valid.
  • Expired, missing, or obscured tags can result in traffic citations, fines, and suspension of your registration.
  • When you register a new vehicle or renew an existing registration, the DMV mails your tags to the address on file, so keeping your address current is essential.
  • Replacement tags are available if yours are damaged, stolen, or lost, and the process and cost vary by state.

How tags connect to your vehicle registration

Your tag number is the link between your physical vehicle and your registration file at the DMV. When you register a vehicle, you provide the vehicle identification number (VIN), proof of ownership, proof of insurance, and payment of registration fees. The DMV then assigns a unique tag number and issues the plates.

The tag itself is proof that registration has been completed. Police, parking enforcement, and toll authorities use the tag number to look up your registration status when ready. If your registration has expired, is suspended, or was never completed, that information appears in their system when they scan your plate.

Some states also use tags to show other information at a glance — for example, whether your vehicle is registered as a commercial vehicle, whether you have a disabled person permit, or what county you registered in. The format and colors of tags vary by state and sometimes by vehicle type.

When you receive tags and how to display them

When you complete vehicle registration at the DMV or online, the agency mails your tags to the mailing address you provided. Delivery usually takes one to three weeks. During this waiting period, you may receive a temporary registration document or temporary tag that you can display while waiting for your permanent plates to arrive.

Once your tags arrive, you must attach them to your vehicle before driving on public roads. Most states require one tag on the front of the vehicle and one on the rear. Some states allow a single rear tag for motorcycles or certain vehicle types. Tags must be securely fastened, clearly visible, and not obscured by dirt, damage, or any object that blocks the numbers or letters.

If you move to a new address, update your address with the DMV as soon as possible. If your tags are mailed to an old address and you do not receive them, contact the DMV to request a replacement or to confirm the mailing address on file.

Tag renewal and expiration dates

Every state sets its own renewal schedule. Some states renew tags annually (every 12 months), while others renew every two or three years. Your expiration date is printed on the tag itself and also appears in your registration documents. The DMV typically sends you a renewal notice in the mail before your tags expire.

Renewal can usually be completed online, by mail, or in person at a DMV office, depending on your state and whether your vehicle passes any required inspections. The cost of renewal varies by state and vehicle type. Some states charge a flat fee; others charge based on vehicle weight, age, or value.

If you do not renew before the expiration date, your registration becomes invalid and your tags are no longer legal to display. Driving with expired tags is a traffic violation. If you miss the renewal important date, you may have a grace period (which varies by state) before enforcement begins, but do not rely on this — renew on time to avoid fines and registration suspension.

Replacement tags for damage, loss, or theft

If your tag is damaged, faded, bent, or stolen, you can request a replacement from the DMV. The process and cost vary by state. Some states charge a small fee (typically $5 to $20) for a replacement tag; others provide one free replacement per registration period.

To request a replacement, contact your state DMV office or visit their website. You will need to provide your vehicle information, current registration number, and proof of ownership. If your tag was stolen, some states ask you to file a police report first. Replacement tags are usually mailed to you within one to three weeks.

If you need to drive before the replacement arrives, ask the DMV whether you can use a temporary tag or whether you must wait for the permanent replacement. Do not drive with a missing or illegible tag — this is a traffic violation.

Personalized and specialty tags

Many states offer personalized tags (also called vanity plates), which allow you to choose a custom combination of letters and numbers instead of receiving a random assignment. Personalized tags cost more than standard tags — typically $25 to $100 extra per year depending on your state — and must be requested separately during registration or renewal.

States also issue specialty tags that support specific causes or organizations. These might include military veteran plates, college alumni plates, environmental conservation plates, or plates supporting particular charities. Specialty tags usually cost more than standard tags, and a portion of the fee goes to the organization or cause.

Both personalized and specialty tags must still meet all display and renewal requirements. They expire on the same schedule as standard tags and must be renewed to remain valid.

Scams and safety concerns related to tags

Do not buy tags from anyone other than your state DMV or an authorized DMV agent. Scammers sometimes sell fake tags online or offer to "register" a vehicle for a fee without actually contacting the DMV. Fake tags are illegal to display and can result in criminal charges, not just a traffic ticket.

If you sell your vehicle, transfer the tags to a new vehicle only if your state allows it — rules vary. In most states, tags stay with the vehicle, not the owner. If you keep tags after selling a vehicle, you may be liable for parking tickets or violations that occur after the sale. Remove your tags when you sell the vehicle, or contact the DMV to officially transfer them.

Never obscure, alter, or cover your tag with tape, plastic, or any material that makes the numbers or letters hard to read. This is illegal and can result in a fine. Similarly, do not use a frame or cover that reflects light or makes the tag difficult to photograph or scan.

If you receive a traffic ticket or toll notice for a vehicle you no longer own, contact the DMV when ready to provide proof of the sale date. Provide the buyer's name and contact information if you have it. The DMV can help redirect the notice to the new owner.

Frequently Asked Questions

What should I do if my tags have not arrived after three weeks?

Contact your state DMV and provide your registration number and current mailing address. Confirm that the address on file is correct. If the address is wrong, update it and request a replacement tag to be mailed to the correct location. If the address is correct, the DMV can investigate whether the tag was lost in the mail and issue a replacement.

Can I drive with a temporary tag after my permanent tags expire?

A temporary tag is only valid during the initial registration period while you wait for permanent tags to arrive. Once your permanent tags arrive, you must display them. A temporary tag does not extend your registration expiration date. Renew your registration before the expiration date shown on your permanent tag.

What happens if I get pulled over with expired tags?

You will receive a traffic citation and a fine. The amount varies by state but typically ranges from $50 to $200. In some states, expired tags can also result in registration suspension, which means you cannot legally drive the vehicle until you renew. If you know your tags are about to expire, renew them before that date.

Do I need to return my old tags when I get new ones?

Rules vary by state. Some states ask you to return old tags to the DMV; others allow you to keep them or destroy them. Check your state's DMV website or call to confirm the requirement. If tags must be returned, the DMV will usually provide instructions with your new tags.

Can I use my old tags on a new vehicle?

In most states, no. Tags are assigned to a specific vehicle and cannot be transferred to a different vehicle. When you buy a new vehicle, you must register it and receive new tags. If you sell your old vehicle, remove the tags and either return them to the DMV or destroy them according to your state's rules.
