Where to renew and what you need

You can renew your Missouri license plates at your county assessor's office or through the Missouri Department of Revenue's online system. The online route is faster if you have no changes to your vehicle or address — you can complete it from home and your new plates arrive by mail in about two weeks. If you prefer in-person service or need to make changes to your registration, visit your local assessor's office during business hours.

Before you go or log in, gather your current registration card, proof of insurance, and a valid ID. If your vehicle has changed owners or you've moved, bring a bill of sale or proof of residency. You'll also need to pay the renewal fee, which varies by vehicle weight and type — a standard passenger car typically costs between $100 and $150, but trucks and specialty vehicles may differ.

Key Takeaways

  • Missouri lets you renew plates online through the Department of Revenue website, by mail, or in person at your county assessor's office.
  • Online renewal takes about two weeks for new plates to arrive and works only if your vehicle information and address haven't changed.
  • In-person renewal at the assessor's office is required if you've moved, changed vehicle ownership, or need to update your registration details.
  • Renewal fees depend on your vehicle's weight and type, and you must show proof of current insurance before the assessor will process your request.

Renewing online through the Department of Revenue

The Missouri Department of Revenue website allows you to renew if your vehicle information is current and your insurance is active. Log in with your driver's license number and date of birth, then follow the prompts to confirm your vehicle details and pay the renewal fee by credit or debit card. The system will show you the exact amount owed before you complete payment.

After you submit payment, you'll receive a confirmation number. Your new plates will be mailed to the address on file, usually within 10 to 14 business days. You can continue using your current plates until the new ones arrive. If you don't receive them within three weeks, contact the Department of Revenue to check the status.

Renewing in person at the assessor's office

Visit your county assessor's office with your current registration card, proof of insurance, and a valid ID. If you've moved since your last renewal, bring a utility bill or lease agreement showing your new address. The assessor will verify your information, collect the renewal fee, and issue you new plates on the spot if plates are in stock — otherwise, they'll be mailed to you.

Processing times vary by county, but most offices complete renewals within 15 to 30 minutes. Some counties offer extended hours or satellite offices, so check your local assessor's website for locations and times before you visit. Bringing all required documents the first time saves you a return trip.

Renewing by mail

If you prefer not to visit an office or renew online, you can mail your renewal request to your county assessor. Include your current registration card, a check or money order for the renewal fee, and a copy of your proof of insurance. Write your name and address on the check so the assessor can match it to your account.

Mail renewal takes longer than in-person or online — typically four to six weeks from the time the assessor receives your envelope. New plates will be mailed to your address once processing is complete. Keep a copy of everything you send in case there are questions about your payment or documents.

What happens if your plates expire

Driving with expired plates is a traffic violation in Missouri. You can be stopped and cited, and the fine starts at $50 and increases with each violation. If you're pulled over, you'll need to show proof that you've submitted a renewal request — a confirmation number from online renewal or a receipt from the assessor's office can help, though it doesn't may provide you'll avoid a ticket.

If your renewal is delayed in the mail or you're waiting for an in-person appointment, contact your county assessor to ask about a temporary permit or extension. Some counties issue temporary documentation that lets you drive legally while your new plates are being processed.

Renewing a vehicle with a lien or loan

If you still owe money on your vehicle, the lender's name appears on your registration. You can renew at the assessor's office or online without notifying the lender — the renewal doesn't change the lien status. Bring the same documents you would for any renewal: registration card, proof of insurance, and ID.

The only time you need to contact your lender is if you're paying off the loan and want to remove their name from the title. That's a separate process handled through the Department of Revenue, not part of plate renewal.

Frequently Asked Questions

Can I renew my plates if my insurance has lapsed?

No. Missouri requires proof of current insurance before the assessor will process a renewal. If your policy lapsed, you must purchase new coverage first, then renew your plates. You cannot legally drive without both active insurance and valid plates.

What if I moved and didn't update my address?

You must renew in person at your county assessor's office and bring proof of your new address, such as a utility bill or lease. Online renewal won't work because the system will mail new plates to your old address. Updating your address at renewal prevents future mail from going to the wrong place.

Do I need to renew my plates if I sell my vehicle?

No. Once you sell the vehicle, the new owner is responsible for renewal. You should notify the Department of Revenue that you no longer own the vehicle so you're not billed for future renewals. The buyer will handle their own registration and plates.

How do I know when my plates expire?

Your registration card shows the expiration date, and the month and year are also printed on your license plates themselves. Missouri sends renewal notices by mail about 30 days before expiration, but don't rely on the notice arriving — check your registration card to be sure.

Can I get personalized or specialty plates when I renew?

Yes. You can request personalized plates, disabled veteran plates, or other specialty plates at your county assessor's office or through the Department of Revenue website during renewal. Specialty plates may have different fees, and personalized plates typically cost extra. The assessor will explain your options and the additional cost before you pay.
