Missouri license plate renewal happens through the Missouri Department of Revenue, either online, by mail, or in person at your local license office

You can renew your Missouri plate without visiting an office if you renew online or by mail, though both routes require your current registration and a valid payment method. The online renewal portal at dor.mo.gov is the fastest option and takes about 10 minutes. By mail, you'll send your renewal notice and payment to the address printed on it, which typically takes two to three weeks. In-person renewal at a Missouri license office is when ready but requires a trip during business hours.

Your renewal notice arrives in the mail about 30 days before your plate expires. The expiration date is printed on your current plate itself — the month and year appear in the upper right corner. Missouri does not send a second notice if you miss the first, so check your registration card or plate if you're unsure when you're due.

Key Takeaways

  • Online renewal at dor.mo.gov is the fastest method and requires only your registration number, driver's license number, and a credit or debit card.
  • Your renewal notice arrives about 30 days before expiration; the expiration date is also printed on your current plate in the upper right corner.
  • By mail, send your renewal notice and payment to the address listed on the notice itself, and allow two to three weeks for processing.
  • In-person renewal at any Missouri license office is when ready, but you must bring your current registration card and a valid payment method.
  • Renewing late carries a penalty fee in addition to the standard renewal cost, so renew before your expiration date.

Online renewal through the Missouri Department of Revenue

The Missouri Department of Revenue website at dor.mo.gov has a dedicated renewal portal. You'll need your vehicle registration number (found on your registration card), your driver's license number, and either a Visa, Mastercard, American Express, or Discover card. The system processes the transaction when ready and generates a temporary registration document you can print or save to your phone.

Your new plate arrives by mail within 7 to 10 business days. Until it arrives, the temporary registration document is valid proof that your renewal is pending. Keep it in your vehicle. Online renewal is available 24 hours a day and does not require you to visit an office or mail anything.

Renewing by mail with your renewal notice

When your renewal notice arrives, it includes a return envelope and payment instructions. Write a check or money order for the amount shown, sign the back of the notice if required, and mail both to the address printed on the envelope. Do not send cash through the mail.

Processing takes two to three weeks from the date the Missouri Department of Revenue receives your envelope. Your new plate will arrive separately by mail after processing is complete. If you're unsure whether your payment arrived, you can call the Missouri Department of Revenue at 573-526-2407 with your vehicle identification number (VIN) or registration number to check the status.

Renewing in person at a Missouri license office

Every Missouri county has at least one license office where you can renew when ready. Bring your current registration card, proof of insurance, and a valid payment method (cash, check, debit card, or credit card — policies vary slightly by office). You do not need an appointment at most offices, though some locations accept them to reduce wait time.

Your new plate is issued on the spot. You can drive away with it the same day. To find the license office nearest you, visit dor.mo.gov and search for "license office locations," or call 573-526-2407. Office hours are typically Monday through Friday, 8 a.m. to 5 p.m., but some locations have extended hours or Saturday appointments.

What happens if you renew late

If your plate expires and you have not yet renewed, you are driving with an expired registration. Missouri law allows a grace period of up to 10 days after expiration before a penalty applies, though you should not rely on this. A traffic stop during that window may still result in a citation, and your insurance may not cover an accident if your registration is expired.

Late renewal includes a penalty fee on top of the standard renewal cost. The penalty amount depends on how long your plate has been expired; the longer you wait, the higher the fee. Renew as soon as you receive your notice to avoid the penalty entirely.

Renewal costs and what's included

Missouri license plate renewal costs vary based on your vehicle type and county. Standard passenger vehicle renewal typically ranges from $80 to $120 annually, though some counties charge slightly more or less. The renewal notice you receive shows the exact amount due for your vehicle and county.

Your renewal fee covers the plate itself, registration with the state, and a new registration card. It does not include vehicle inspection, emissions testing, or any other services — those are separate if required. Missouri does not require emissions testing statewide, though some counties in the St. Louis and Kansas City areas do. Check your renewal notice or contact your local license office to confirm whether your county requires it.

Changing your address or vehicle information

If you've moved since your last registration or need to update other information, you cannot make those changes through online renewal. Instead, renew in person at a license office or call 573-526-2407 to request a renewal form by mail that includes address change fields. Bring proof of your new address (utility bill, lease, or mortgage statement dated within 60 days) when you renew in person.

If you've sold your vehicle or bought a new one, you need a new registration, not a renewal. That process is separate and requires a bill of sale, proof of ownership, and proof of insurance. Contact your local license office for the specific documents needed.

Frequently Asked Questions

Can I renew my Missouri plate before the renewal notice arrives?

Yes. You can renew online at dor.mo.gov anytime using your registration number, even if your notice hasn't arrived yet. Check your registration card or current plate for the expiration date. You don't have to wait for the notice to begin the process.

What if I lose my renewal notice?

You don't need the notice to renew online — just use your registration number and driver's license number at dor.mo.gov. If you prefer to renew by mail or in person, call 573-526-2407 and ask for a replacement notice, or visit a license office and they can look up your account.

Do I need a vehicle inspection to renew my Missouri plate?

No. Missouri does not require a safety inspection for plate renewal statewide. However, some counties in the St. Louis and Kansas City areas require emissions testing. Your renewal notice will state whether emissions testing is required for your vehicle and county.

How long is my temporary registration valid while I wait for my new plate?

If you renew online, your temporary registration is valid until your new plate arrives, which typically takes 7 to 10 business days. Keep the temporary document in your vehicle. If you renew by mail, the grace period is typically 10 days after your old plate expires, though you should not rely on this — renew before expiration to avoid any risk.

Can someone else renew my plate for me?

For online renewal, only you can log in and complete the transaction. For in-person renewal, another person can renew on your behalf if they bring your registration card, proof of insurance, and payment, though some offices may require a signed authorization letter. Call your local license office ahead of time to confirm their policy.
