What Missouri license plates are and who needs them

A Missouri license plate is the metal tag you mount on the front and back of your vehicle to show that you have registered it with the state. Every vehicle driven on a Missouri public road must have a current plate. The plate displays your registration number, the state name, and a validation sticker that shows your registration is current.

You need a plate when you buy a vehicle, move to Missouri from another state, or renew an expired registration. Missouri issues different plate types depending on what you drive — standard passenger plates, commercial plates for trucks and vans, motorcycle plates, and specialty plates that support specific causes or organizations.

The Missouri Department of Revenue handles all plate issuance and registration. You obtain plates through your county assessor's office, not through a separate DMV, which is an important difference from many other states.

Key Takeaways

  • You get Missouri plates through your county assessor's office, not a state DMV office, so you need to know which county you live in.
  • New vehicle registration requires proof of ownership, proof of residency, and a completed process form, and takes about 30 minutes in person.
  • Plate renewal happens every two years and can be done by mail, online, or in person at your assessor's office.
  • Missouri plates expire on your birthday in even-numbered years, so your renewal date depends on when you first registered the vehicle.
  • Specialty plates cost more than standard plates but support specific causes, and you can switch between them or back to standard plates at renewal.

Getting plates for a new vehicle in Missouri

When you buy a vehicle in Missouri, you have 30 days to register it and get plates. Go to your county assessor's office with your bill of sale or title, proof that you live in Missouri (a utility bill or lease works), and a completed Form 108 (process for Missouri License Plates and Registration). The assessor will verify the vehicle identification number (VIN) matches your paperwork, calculate your registration fee based on the vehicle's age and weight, and issue your plates on the spot.

If you are buying from a dealer, they often handle the paperwork and send you to the assessor's office with everything prepared. If you are buying from a private seller, you complete the transaction yourself and then visit the assessor. Bring the signed title or bill of sale showing you as the new owner.

Registration fees vary by county and by vehicle type. A standard passenger vehicle typically costs between $150 and $250 for the first registration, though this varies. You pay once every two years at renewal. If you buy a vehicle partway through the registration cycle, you pay a prorated fee that covers only the remaining months until your next renewal date.

Renewing your Missouri plates by mail or online

Missouri plates expire every two years on your birthday. About 60 days before expiration, your county assessor's office mails you a renewal notice with your renewal fee and instructions. You can renew by mail by returning the notice with a check, by paying online through your county assessor's website, or by visiting the office in person.

Online renewal is the fastest option if your county offers it. Log into your assessor's website, enter your plate number and last name, review the renewal fee, and pay by credit card or debit card. Your new validation sticker arrives by mail within one to two weeks. You must place the sticker on your current plate — you do not receive a new physical plate unless yours is damaged or you are changing plate types.

Mail renewal takes longer because the assessor's office must receive your payment, process it, and mail your sticker back to you. Allow at least three weeks. If you miss the renewal important date, you can still renew, but you may owe a late fee in addition to the renewal cost. Driving on an expired plate is illegal and can result in a traffic citation.

Transferring plates from another state

If you move to Missouri from another state and bring a vehicle with you, you must register it in Missouri within 30 days. You cannot keep your old state's plates. Visit your county assessor's office with your out-of-state title or registration, proof of Missouri residency, and the completed Form 108.

The assessor will issue new Missouri plates and a new registration. You can surrender your old plates to the assessor's office, or you can mail them back to your previous state's DMV if you prefer. Missouri does not require you to return out-of-state plates, but returning them closes your account with that state and prevents confusion if the plates are later found or misused.

Your registration fee as a new Missouri resident is based on the vehicle's current age and weight, not on what you paid in your previous state. If you registered the vehicle recently in your old state, you may be able to transfer some of that registration period to Missouri, which would lower your first-year fee. Ask the assessor about credit for prior registration when you explore.

Specialty plates and vanity plates in Missouri

Missouri offers specialty plates that support causes like veterans' organizations, wildlife conservation, and higher education. These plates cost $25 to $50 more per registration cycle than a standard plate, and the extra fee goes to the organization the plate supports. You choose a specialty plate type when you first register or at any renewal.

Vanity plates — custom plates with letters and numbers you choose — are also available. You request a vanity plate through your assessor's office on Form 108-V. The assessor checks whether your requested combination is available. Vanity plates cost an additional $50 per registration cycle beyond the standard registration fee. You can keep the same vanity combination for as long as you renew it, or you can change it at any renewal.

If you have a specialty or vanity plate and want to switch back to a standard plate, you can do so at renewal without penalty. straightforward request a standard plate on your renewal form. Your new standard plate arrives with your validation sticker.

Replacing lost, stolen, or damaged plates

If your plate is lost, stolen, or damaged, visit your county assessor's office and request a replacement. Bring your current registration card or a photo ID showing your name and address. The assessor will issue a new plate with the same registration number. The replacement fee is typically $15 to $25, though this varies by county.

If your plate was stolen, you may want to file a police report first, though it is not required to get a replacement. The report creates a record in case the plate is later found or misused. Bring the report number to the assessor's office when you request the replacement.

Damaged plates that are still readable do not need to be replaced when ready, but if the number is faded, bent, or obscured, you should replace it. An unreadable plate can result in a traffic citation. Replacement plates are issued the same day you request them.

What to do if your registration expires while you are out of state

If you are traveling or living temporarily outside Missouri and your registration expires, you can renew by mail or online without returning to the state. Use the renewal notice mailed to you before expiration, or contact your county assessor's office by phone to request a renewal form. Pay by check or credit card and mail the form back, or renew online if your county offers that option.

Your new validation sticker will be mailed to the address on file with the assessor. If you have moved temporarily and want the sticker mailed to a different address, call your assessor's office before you renew and update your mailing address. Once your sticker arrives, place it on your current plate and you are legal to drive in Missouri again.

If your registration expires and you do not renew before you drive back into Missouri, you are driving illegally. Renew as soon as you realize the expiration date has passed, even if you are out of state. The renewal is retroactive to your expiration date, so you will not owe additional penalties as long as you renew promptly.

Frequently Asked Questions

Can I get a temporary plate while I wait for my permanent plate?

Missouri does not issue temporary plates. When you register a vehicle at your county assessor's office, you receive your permanent plate the same day. You can drive when ready with that plate. If you are buying from a dealer, ask whether they can issue a temporary tag that is valid for a few days while you complete registration — some dealers do this as a courtesy.

What if I move to a different county in Missouri?

You do not need to re-register your vehicle or get new plates when you move within Missouri. Your registration remains valid until your renewal date. Update your address with your new county assessor's office so renewal notices reach you at the correct address. You can do this by phone or by visiting the office in person with proof of your new address.

Do I need to remove my old plate before getting a new one?

Yes. When you renew and receive a new validation sticker, remove the old sticker from your current plate and place the new one in the same location. You keep the same physical plate unless it is damaged or you are switching plate types. Do not display both stickers at once — only the current sticker should be visible.

What happens if I sell my vehicle?

When you sell your vehicle, notify your county assessor's office that the vehicle has been sold. You can do this by phone or in person. The assessor will cancel your registration and you will not be charged for the next renewal cycle. The new owner must register the vehicle in their name before driving it. If you have a vanity plate, you can request to keep it for a future vehicle, or it will be released for someone else to use.

Can I renew my registration if my plate is damaged?

Yes. You can renew your registration by mail or online even if your plate is damaged, as long as you can provide your plate number. At your next renewal, request a replacement plate at the same time. The assessor will issue both your validation sticker and a new plate together, or you can visit the office in person to replace the damaged plate when ready.
