Missouri license plates renew every two years, and you can do it by mail, online, or in person at your local license office

Missouri sends renewal notices about 30 days before your plates expire. The notice tells you the exact amount due, your plate number, and your options for renewing. You do not have to wait for the notice to arrive — you can renew up to six months early if you want to avoid the rush closer to your expiration date.

The fastest route is online through the Missouri Department of Revenue website, where you can renew in minutes if your vehicle has passed inspection and you have no outstanding violations or unpaid fines. If you prefer not to go online, you can mail in your renewal notice with a check or money order, or walk into any Missouri license office with your notice and payment. All three methods take about the same amount of time to process once received, though in-person renewal is when ready if everything is in order.

Key Takeaways

  • Missouri sends renewal notices 30 days before expiration, but you can renew up to six months early online or by mail.
  • Online renewal through the Missouri Department of Revenue website is the fastest option and takes just a few minutes if your vehicle has passed inspection.
  • You can also renew by mail using your renewal notice and a check, or in person at any Missouri license office with your notice and payment method.
  • Your vehicle must have a current safety inspection on file before you can renew, and you cannot renew if you have unpaid traffic violations or fines.
  • New plates arrive by mail within two to three weeks of approval; you can continue driving on your old plates until the new ones arrive.

What you need to renew online

To renew through the Missouri Department of Revenue website, you will need your renewal notice (or your plate number and driver's license number if you do not have the notice), your vehicle identification number (VIN), and a payment method — debit card, credit card, or electronic check. The website will ask you to confirm your vehicle information and current address.

Before you start, check that your vehicle has a current safety inspection. Missouri requires all vehicles to pass a safety inspection every two years, and the inspection must be on file before the Department of Revenue will process your renewal. If your inspection has expired or you have never had one, you will need to visit a certified inspection station first — this is a separate step from renewal and costs around $25 to $30, though the exact amount varies by station.

If you have unpaid traffic violations, parking tickets, or other fines on your record, the system will flag your account and you will not be able to complete the renewal online. You will need to settle those debts first, either by paying them directly to the court or municipality that issued the ticket, or by contacting the Missouri Department of Revenue to find out what is blocking your renewal.

Renewing by mail with your renewal notice

If you received a renewal notice in the mail, you can send it back with payment without going online or to an office. Write a check or money order for the amount shown on the notice, sign the back of the notice itself, and mail both to the address printed on the notice. Do not send cash.

Mail renewal takes longer than online renewal because the Department of Revenue has to receive your envelope, process it, and mail your new plates back to you. Plan for five to seven business days for the Department to receive and process your renewal, then another two to three weeks for your new plates to arrive by mail. You can continue driving on your old plates during this time — there is no gap in your registration.

If you did not receive a renewal notice or lost it, you can still renew by mail. Contact the Missouri Department of Revenue to request a renewal form, or visit a license office in person to pick one up. The form will ask for your plate number, VIN, current address, and payment information.

Renewing in person at a Missouri license office

Walk-in renewal is available at any Missouri license office during business hours. Bring your renewal notice, your driver's license or state ID, proof of your current address (a utility bill or lease dated within the last 60 days works), and payment in cash, check, or card. If you do not have your renewal notice, bring your plate number and VIN instead.

Your vehicle must have a current safety inspection on file before the office can process your renewal. If it does not, you will need to visit an inspection station first, then return to the license office. The office staff can tell you when ready whether your inspection is current and whether anything else is blocking your renewal.

If you renew in person and everything is in order, you can leave with a temporary registration document that day. Your permanent plates will arrive by mail within two to three weeks. The temporary document is valid for driving until your new plates arrive.

Safety inspection requirements before renewal

Missouri requires a safety inspection every two years, and your inspection must be current before you can renew your plates. The inspection checks your brakes, lights, windshield wipers, horn, steering, suspension, and exhaust system. It does not include emissions testing in most of Missouri, though a few counties in the St. Louis and Kansas City areas do require emissions tests as part of the safety inspection.

You can get a safety inspection at any certified inspection station — these include many independent repair shops, tire shops, and dealerships. The inspection costs between $25 and $30 depending on the station. Once you pass, the station sends the results electronically to the Missouri Department of Revenue, and your inspection is on file when ready. You do not need to bring a certificate or proof of inspection when you renew; the Department of Revenue can see it in their system.

If your inspection expired or you have never had one, you cannot renew your plates until you pass a new inspection. This is a hard requirement — there are no exceptions or extensions. Plan to visit an inspection station before you attempt to renew online or by mail.

What happens if your plates expire before you renew

If your plates expire and you have not yet renewed, you cannot legally drive the vehicle on public roads. If you are stopped by police, you will be cited for expired registration, which carries a fine. The fine amount varies by county but typically ranges from $50 to $200 for a first offense.

If your plates have expired, you can still renew them at any time. Visit a license office in person with your driver's license, proof of address, and payment, or renew online if your vehicle has a current inspection. The renewal process is the same whether your plates are current or expired. Once your renewal is processed, you can drive legally again, even if you are still waiting for your new plates to arrive in the mail.

If you were cited for expired registration, renewing your plates does not automatically dismiss the ticket. You will need to handle the traffic citation separately — either by paying the fine, contesting it in court, or checking whether your county offers a dismissal program for people who renew their registration after a citation.

Cost of Missouri license plate renewal

The cost of renewing your plates depends on your vehicle type and county. Passenger cars typically cost between $100 and $150 for a two-year renewal, though the exact amount varies by county. Trucks, motorcycles, and commercial vehicles have different rates. Your renewal notice will show the exact amount due for your vehicle.

Some counties offer a small discount if you renew early, though this is not universal. Check your renewal notice to see whether a discount applies to you. If you renew online, by mail, or in person, the cost is the same — there are no additional fees for choosing one method over another.

If you need to replace a lost or damaged plate before your renewal date, that is a separate transaction with its own fee, typically around $10 to $15. You can request a replacement plate at any license office or through the mail.

Frequently Asked Questions

Can I renew my plates if my vehicle has not passed inspection?

No. Missouri requires a current safety inspection before renewal, and the Department of Revenue will not process your renewal without one on file. You must visit a certified inspection station first, pass the inspection, and then renew your plates. The inspection and renewal are two separate transactions.

What if I move to a different county or address before my plates expire?

You do not need to renew your plates when you move within Missouri. Your registration stays valid until the expiration date on your plates, even if you change address. When you renew, you can update your address at that time. If you move out of Missouri, you will need to register your vehicle in your new state.

How long can I drive on expired plates before I get a ticket?

You cannot legally drive on expired plates at all. If you are stopped by police after your plates expire, you will be cited. Renew your plates before the expiration date shown on your current plates, or renew them when ready if they have already expired.

Can I renew my plates if I have an outstanding traffic ticket?

No. If you have unpaid traffic violations or fines, the Missouri Department of Revenue will not process your renewal. You must pay the ticket or resolve it with the court first. Contact the court or municipality that issued the ticket to find out how to settle it, then you can renew your plates.

Do I need to do anything special to renew if I bought my vehicle used?

No. As long as you have a current safety inspection and no unpaid violations, you can renew the plates the same way as anyone else. The inspection must be on file in your name, so if you just bought the vehicle, make sure you get an inspection at a certified station before you attempt to renew.
