Legal tags are the registration plates your state or province issues to prove your vehicle is registered and insured

A legal tag—also called a license plate or registration plate—is an official metal or plastic plate issued by your state's Department of Motor Vehicles (or equivalent body) that displays a unique combination of letters and numbers. It serves as proof that your vehicle has been registered with the state and that you have met the insurance requirements for that registration period. Every vehicle driven on public roads must display at least one legal tag, and most states require two (front and rear).

The tag itself is not your registration document. Your registration is a separate paper or digital record that shows ownership, vehicle identification number (VIN), and the dates your registration is valid. The tag is the visible proof that you have current registration—it is what a police officer sees when they run your plate, and what tells other drivers that your vehicle is legally on the road.

Key Takeaways

  • Legal tags are issued by your state's Department of Motor Vehicles and must be displayed on the front and rear of your vehicle in most states.
  • A tag proves your vehicle is registered and insured, but the tag itself is not your registration document—that is a separate record you keep in your vehicle.
  • Tags expire on a date set by your state, usually one to two years from issue, and you must renew them before that date or face fines and potential vehicle impoundment.
  • Personalized or vanity tags cost more than standard tags but use the same registration and renewal process.
  • If your tag is lost, stolen, or damaged, you can request a replacement from your DMV, usually for a small fee.

How legal tags connect to your registration and insurance

When you register a vehicle with your state, the DMV issues a registration certificate and a set of legal tags. The registration certificate is the official document; the tag is the proof you display. Your insurance company reports your active policy to the state, and the state will not issue or renew a tag unless you have proof of insurance on file. This is why you cannot legally drive without both a current tag and active insurance—they are linked in the state's system.

The tag displays your vehicle's registration number, which the state uses to look up your registration record, ownership, and insurance status. When a police officer scans your plate, they see all of this information when ready. If your registration has expired or your insurance has lapsed, the officer will know when ready, even if the tag itself looks new.

Standard tags versus personalized or vanity tags

Most states issue standard tags with a combination of letters and numbers assigned by the DMV. These are included in your registration fee. Personalized or vanity tags let you choose your own combination of letters, numbers, or both—within the state's character limits and rules. Vanity tags cost more than standard tags (usually $25 to $100 extra per year, depending on the state) and go through a separate approval process to make sure your chosen combination is not already taken and does not violate the state's content rules.

The renewal process for vanity tags is the same as for standard tags—you renew them on the same schedule and pay the same registration fee plus the vanity plate surcharge. If you decide you no longer want a vanity tag, you can switch back to a standard tag at your next renewal.

Tag expiration dates and renewal timing

Your legal tag has an expiration date printed on it, usually in the bottom right corner. Most states set expiration dates one or two years from the issue date, though some states use staggered expiration dates based on your vehicle's registration month. You must renew your tag before the expiration date or you will be driving with an expired tag, which is a traffic violation and can result in a fine.

You can usually renew your tag 30 to 60 days before it expires. Many states allow you to renew online through the DMV website, by mail, or in person at a DMV office or authorized agent (such as a local auto tag office). When you renew, you will need to provide proof of current insurance and pay the renewal fee. If your vehicle's registration or insurance has lapsed, you may need to re-register the vehicle before you can renew the tag.

What happens if your tag is lost, stolen, or damaged

If your tag is stolen or damaged beyond readability, you can request a replacement from your state's DMV. You will need to report the theft or damage (some states require a police report for theft) and pay a replacement fee, which is usually $10 to $30. The replacement tag will have the same registration number as your original tag and will be valid until your original expiration date.

If your tag is straightforward missing a screw or bracket, you can often repair it yourself or have a local auto parts store help you. If the tag is bent, faded, or the numbers are no longer readable, a replacement is the safest option because an unreadable tag can result in a traffic stop and a fine.

Temporary tags and when you might see them

When you buy a new or used vehicle and register it for the first time, the DMV issues a temporary tag (also called a temporary registration or dealer plate) while your permanent legal tag is being made. Temporary tags are usually paper stickers or cardboard plates valid for 30 to 60 days. You must display the temporary tag in your rear window until your permanent tag arrives in the mail.

Temporary tags are also issued when you are waiting for a replacement permanent tag or when you have just moved to a new state and are re-registering your vehicle. The rules for displaying and using a temporary tag are the same as for a permanent tag—you must have it visible and you must not drive after it expires.

Penalties for expired, missing, or unreadable tags

Driving with an expired tag is a traffic violation in every state. The fine varies by state but typically ranges from $50 to $200 for a first offense. A missing or unreadable tag can result in a similar fine and a traffic stop. If you accumulate multiple violations or ignore renewal notices, your vehicle registration can be suspended, which means you are no longer legally permitted to drive the vehicle. A suspended registration can also lead to vehicle impoundment if you are stopped by police.

The best way to avoid these penalties is to renew your tag before the expiration date. Set a reminder on your phone or calendar 60 days before your tag expires, or sign up for renewal reminders through your state's DMV website if that option is available.

Frequently Asked Questions

Do I need to display a tag on the front and back of my vehicle?

Most states require two tags—one on the front and one on the rear of your vehicle. A few states allow a single rear tag. Check your state's DMV website or your vehicle's registration certificate to confirm the requirement for your state. If you are unsure, display tags on both the front and rear to be safe.

Can I drive with an expired tag if I have already sent in my renewal?

No. You must not drive with an expired tag, even if you have submitted your renewal process. If your renewal is delayed, you can request a temporary tag from the DMV to use while you wait for your permanent tag to arrive. Contact your state's DMV to find out how to request a temporary tag.

What do I do if my tag was stolen?

Report the theft to your local police department and obtain a police report number. Then contact your state's DMV with the report number and request a replacement tag. You will pay a replacement fee, usually $10 to $30. The new tag will have the same registration number and expiration date as your original tag.

Can I transfer my personalized tag to a new vehicle?

Most states allow you to transfer a vanity tag to a different vehicle you own, but the process and fees vary. Contact your state's DMV to ask about transfer options. Some states charge a transfer fee, and some require you to re-register the new vehicle first before the tag can be transferred.

What if I move to a new state?

When you move to a new state, you must re-register your vehicle with that state's DMV within a set time frame (usually 30 to 90 days). You will receive a new legal tag with that state's format and design. You cannot use your old state's tag in your new state, even if it has not expired yet.
