Where to renew and what you need

You can renew Missouri plates in person at your local Missouri Department of Revenue office, by mail, or online through the Missouri Secretary of State website. The online option is fastest if your vehicle has no safety or emissions issues — you can complete it in minutes and receive your new registration by mail within two weeks.

Before you start, gather your current registration card, proof of insurance, and a valid ID. If your address has changed since your last renewal, bring proof of your new address (a utility bill or lease works). You will also need proof that your vehicle passed the required safety inspection and emissions test, if your county requires one.

The renewal fee varies by vehicle weight and type. A standard passenger car typically costs between $100 and $150 for a two-year registration, but commercial vehicles, trailers, and motorcycles have different rates. Check the Secretary of State website or call your local revenue office to confirm the exact amount for your vehicle before you go in.

Key Takeaways

  • Online renewal through the Missouri Secretary of State website is the fastest option and takes about two weeks for your new plates to arrive by mail.
  • You must have a current safety inspection and emissions test (if required in your county) before you can renew, so schedule those first if they have expired.
  • Proof of current auto insurance is required at renewal — bring your insurance card or a declaration page from your insurer.
  • Renewal fees depend on your vehicle's weight and type, so confirm the amount with your local revenue office or the state website before paying.

Online renewal through the Secretary of State

The Missouri Secretary of State's online renewal system is open 24 hours and requires no appointment. Go to the Secretary of State website, select "Vehicle Registration Renewal," and enter your license plate number and vehicle identification number (VIN). The system will pull up your current registration and show you the renewal fee.

You can pay online by debit card or credit card. Once your payment is processed, you will receive a confirmation number. Your new registration card and plates will be mailed to the address on file — allow 10 to 14 business days for delivery. You can continue to drive with your current plates during this time as long as your current registration has not yet expired.

Online renewal is not available if your vehicle failed inspection, if you have unpaid violations or fines, or if your registration has been suspended. In those cases, you must visit a revenue office in person.

In-person renewal at a Missouri Department of Revenue office

Walk into any Missouri Department of Revenue office with your current registration, proof of insurance, and a valid ID. Bring your vehicle's safety inspection and emissions test results if your county requires them. The staff will verify your information, collect the renewal fee, and issue you a new registration card on the spot.

You will receive temporary registration paperwork valid for 30 days while you wait for your permanent plates to arrive by mail. Bring this paperwork with you when you drive. Your new plates will be mailed within two to three weeks.

Revenue office wait times vary by location and time of day. Offices are typically less busy on weekday mornings and more crowded on Fridays and the first week of the month. Check the Department of Revenue website for your local office's hours and location.

Renewing by mail

If your registration is current and your vehicle has no safety or emissions violations, you can renew by mail. The Missouri Department of Revenue will send you a renewal notice 30 to 60 days before your registration expires. The notice includes a payment envelope and instructions.

Fill out the form, include your proof of insurance, and mail it with a check or money order to the address on the notice. Do not send cash. Processing takes two to four weeks from the date the office receives your envelope, so mail it at least three weeks before your registration expires to avoid a lapse.

Keep a copy of everything you mail for your records. If your renewal notice does not arrive, contact your local revenue office — they can send you a duplicate or tell you whether your registration is still active.

Safety inspection and emissions testing requirements

Missouri requires a safety inspection for all vehicles. The inspection covers brakes, lights, windshield wipers, horn, steering, and other safety systems. You can get this inspection at any Missouri state inspection station — most are run by independent mechanics, tire shops, and service stations. The inspection costs around $10 to $15 and is valid for one year.

Emissions testing is required only in certain counties in the St. Louis and Kansas City areas. If you live in one of these counties, your vehicle must pass an emissions test within the past 12 months before you can renew. The test costs around $25 to $30 and checks your vehicle's exhaust system. If your vehicle fails, you have 30 days to fix the problem and retest at no additional charge.

Schedule your inspection and emissions test before you renew your registration. You will need the inspection and test results (or the inspection station's stamp on your registration) when you renew online, by mail, or in person.

What happens if your registration expires

Driving with an expired registration is illegal in Missouri and can result in a traffic ticket and fine. If you are pulled over, the officer will cite you for operating an unregistered vehicle. The fine starts at $100 and can go higher depending on how long your registration has been expired.

If your registration has expired, you can still renew it at any time. There is no grace period, but there is also no penalty fee added to the renewal cost — you pay the standard renewal fee. However, if you have unpaid traffic tickets or violations, the revenue office may hold your renewal until those are resolved.

If you are unsure whether your registration is still valid, check the expiration date on your registration card or call your local revenue office. They can tell you the status over the phone.

Renewing a vehicle with a lien or loan

If you are still paying off a car loan or have a lien on your vehicle, the lender's name will appear on your registration. You can renew your registration without the lender's permission — the lender does not need to sign off on renewal. straightforward follow the standard renewal process online, by mail, or in person.

The lender will receive a copy of your new registration automatically. If your vehicle is paid off and the lender's name is still on the registration, contact your lender to request a lien release, then bring that release to a revenue office to update your registration.

Frequently Asked Questions

Can I renew my plates if my vehicle failed the safety inspection?

No. You must pass the safety inspection before you can renew. Fix the failed items, return to the inspection station for a retest, and then renew your registration. The retest is usually free if done within 30 days of the first failure.

What if I move to a different county or state?

If you move within Missouri, you can renew your registration at your new county's revenue office. Bring proof of your new address. If you move out of state, you will need to register your vehicle in your new state instead of renewing in Missouri — contact your new state's motor vehicle department for their process.

How long can I drive after my registration expires?

You cannot legally drive at all once your registration expires. There is no grace period. If you are pulled over with an expired registration, you will receive a ticket. Renew before the expiration date on your card.

Can someone else renew my plates for me?

Yes. If you renew by mail or online, someone else can mail the form or complete the transaction on your behalf. For in-person renewal, the person renewing must bring your current registration, proof of insurance, and a valid ID — they do not need a power of attorney.

What if I lost my registration card?

You can still renew. Bring your vehicle's VIN (found on the dashboard or in your insurance documents), proof of insurance, and a valid ID to a revenue office. The staff can look up your registration by VIN and process your renewal. You can also request a duplicate registration card at the same time.
