Where to renew your Missouri plates

You can renew your 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 the fastest if your vehicle has no safety or emissions issues and your registration is not expired by more than one year.

In-person renewal at a revenue office takes about 30 minutes on average, though wait times vary by location and time of day. Mail renewal takes two to three weeks from the time the department receives your process. Online renewal is when ready — you pay the fee and print a temporary registration while your new plates are mailed to you.

You must renew in person if your vehicle failed a safety or emissions inspection, if your registration has been expired for more than one year, or if you need to change the vehicle's information (such as the VIN or owner name).

Key Takeaways

  • Online renewal through the Missouri Secretary of State website is the fastest option if your vehicle passed inspection and your registration is current or less than one year expired.
  • You will need your current registration card, proof of a passing safety or emissions inspection (if required for your vehicle), and payment by credit or debit card.
  • Mail renewal takes two to three weeks, while in-person renewal at a Department of Revenue office usually takes 30 minutes.
  • Renewing in person is required if your registration is more than one year expired, if your vehicle failed inspection, or if you need to update vehicle information.
  • Your new plates will be mailed to the address on file, and you can use a temporary registration while you wait for them to arrive.

What documents and information you need

For any renewal method, you will need your current registration card and proof of payment for the renewal fee. The fee varies depending on your vehicle's weight and whether you are renewing for one or two years. Missouri does not publish a single fee schedule online — the amount is calculated based on your specific vehicle, so you will see the exact cost when you begin the renewal process.

If your vehicle is subject to a safety inspection (most passenger vehicles in Missouri), you must have a passing inspection completed within the 12 months before you renew. If your vehicle is subject to an emissions test (required in certain counties), that test must also be current. You will need the inspection or test results when you renew — the Department of Revenue can look them up by your vehicle identification number (VIN), but having the paperwork on hand speeds the process.

For online renewal, you will also need a valid credit or debit card. For mail renewal, you can pay by check, money order, or credit card.

Renewing online through the Missouri Secretary of State

Go to the Missouri Secretary of State's vehicle registration renewal portal and enter your vehicle's license plate number and VIN. The system will pull up your current registration and show you the renewal fee. You will need to confirm that your vehicle has passed any required safety or emissions inspections — the system checks this against the inspection database, but if there is a delay in the records, you may need to provide proof manually.

Once you confirm the information and pay the fee by credit or debit card, you will receive a temporary registration number that you can print when ready. This temporary registration is valid for 30 days and allows you to drive legally while your new plates are in the mail. Your permanent plates will arrive within two to three weeks at the address on file.

If the system cannot verify your inspection status or if your registration is expired by more than one year, you will be directed to renew by mail or in person instead.

Renewing by mail

Request a renewal form from your local Department of Revenue office, or read the form from the Missouri Secretary of State website. Fill out the form completely, including your current registration card information and your VIN. Attach a copy of your passing safety or emissions inspection results (if required), and include payment by check or money order made out to the Missouri Department of Revenue.

Mail the completed form and payment to the address listed on the form — this varies by county. Include a self-addressed, stamped envelope if you want the department to return a receipt. Processing takes two to three weeks from the date the department receives your process. You can continue driving on your current plates during this time.

If the department finds an issue with your process (such as missing inspection results or an illegible signature), they will contact you by mail, which adds time to the process. To avoid delays, double-check that all required fields are filled in and that your inspection documents are clear and current.

Renewing in person at a Department of Revenue office

Bring your current registration card, your vehicle's title or proof of ownership, a valid photo ID, and proof of a passing safety or emissions inspection (if required). Some offices accept walk-ins, but many now use appointment systems — check your local office's website or call ahead to see if you need to book a time slot.

The staff will verify your inspection status, calculate your renewal fee, and process your payment. You will receive a temporary registration on the spot, and your new plates will be mailed to you within two to three weeks. In-person renewal is the best option if you have questions about your registration, if your inspection status is unclear, or if you need to update your address or vehicle information at the same time.

Safety and emissions inspection requirements

Most passenger vehicles registered in Missouri must pass a safety inspection every two years. The inspection checks your brakes, lights, windshield wipers, horn, and other safety equipment. Emissions testing is required only in certain counties (primarily the St. Louis and Kansas City areas) and only for vehicles model year 1996 and newer.

You can have your inspection done at any Missouri-licensed inspection station — these include many repair shops, tire shops, and service stations. The inspection takes about 15 minutes and costs between $10 and $25 depending on the station. Once you pass, the results are recorded in the state database and are valid for 12 months from the inspection date.

If your vehicle fails inspection, you have 30 days to fix the problem and retest at no additional charge. You cannot renew your registration until you have a passing inspection on file.

What to do if your registration is expired

If your registration has been expired for less than one year, you can renew online or by mail using the standard process. If it has been expired for more than one year, you must renew in person at a Department of Revenue office. Bring your current title, a valid photo ID, and proof of a passing safety inspection.

Driving with an expired registration is illegal in Missouri and can result in a traffic citation. If you are stopped by law enforcement, you may be fined. Renewing as soon as possible protects you from this risk and ensures your vehicle is properly registered.

Frequently Asked Questions

Can I renew my plates before they expire?

Yes. Missouri allows you to renew your registration up to 90 days before the expiration date. Renewing early does not shorten the validity of your new registration — your new plates will be valid for the full two-year period from the date you renew.

What if I move to a different address after I renew?

You can update your address with the Department of Revenue at any time. If you have already renewed and your new plates are in the mail, contact the department to have them sent to your new address instead. You can also update your address in person at any Department of Revenue office.

How long can I drive on a temporary registration?

Your temporary registration is valid for 30 days. If your new plates have not arrived by then, contact the Department of Revenue to request a replacement temporary registration or to check on the status of your plates.

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

No. When you sell your vehicle, the registration transfers to the new owner. You do not need to renew plates that are no longer on your vehicle. The new owner will handle registration in their own name.

What if my inspection failed and I need to renew soon?

Fix the issue that caused the failure and have the vehicle retested at any licensed inspection station. Once you have a passing inspection, you can renew online, by mail, or in person using the standard process. There is no penalty for a failed inspection — you straightforward cannot renew until you pass.
