Renew your Cobb County tag online, by mail, or in person at a Tag Office

Cobb County vehicle tag renewal happens through the Cobb County Tax Assessor's Office, not through the state. You can renew online at cobbassessor.us, mail in your renewal notice, or visit a Tag Office location in person. Online renewal is the fastest option and takes a few minutes if you have your current tag number and a valid payment method. The renewal notice arrives in the mail about 30 days before your tag expires, and that notice contains everything you need to renew.

Your tag expires on the last day of the month shown on your current tag. If you renew before that date, your new tag is valid when ready. If you renew after expiration, you can still renew without penalty as long as you do so within a reasonable time — but driving with an expired tag is illegal, so do not delay.

Keep a copy of your renewal notice for your records. Your new tag will arrive by mail after the Tax Assessor's Office processes your payment, typically within 10 to 14 business days from receipt. If you do not receive your renewal notice 30 days before expiration, contact the Tax Assessor's Office to request one.

Renewing in person at a Cobb County Tag Office

Cobb County operates multiple Tag Office locations throughout the county. Bring your current tag (or the vehicle itself), your driver's license, and your renewal notice if you have it. You can pay by cash, check, debit card, or credit card. The office will issue your new tag on the spot, and you can drive home with it the same day.

Tag Office hours vary by location. Most are open Monday through Friday during standard business hours, with some locations offering limited Saturday hours. Check cobbassessor.us for the location nearest you and its specific hours before you go. Arriving early in the week typically means shorter wait times than Friday afternoons.

What happens if your tag expires before you renew

If your tag expires and you have not yet renewed, you can still renew through any of the three methods above without penalty. However, driving with an expired tag is illegal in Georgia, and you can be stopped and cited by law enforcement. The citation carries a fine and can result in points on your driving record.

If you are stopped with an expired tag, tell the officer you have already renewed or are in the process of renewing. Having your renewal confirmation or renewal notice with you can help, though it does not may provide the officer will not issue a citation. The safest approach is to renew before your tag expires.

Understanding your renewal fee

Your renewal fee is based on your vehicle's age, type, and assessed value. The amount appears on your renewal notice. Passenger vehicles typically cost less to renew than commercial vehicles or trailers. If you believe your vehicle's assessed value is incorrect, you can file a value appeal with the Tax Assessor's Office, though this process is separate from renewal and does not delay your tag.

Some vehicles may may have access to for reduced fees or exemptions — for example, disabled veteran plates or certain agricultural vehicles. If you think your vehicle qualifies for a special rate, contact the Tax Assessor's Office before renewing to confirm.

If you lose your renewal notice or need help

If your renewal notice does not arrive or you lose it, you can still renew online using your tag number and VIN, or visit a Tag Office in person with your driver's license and current tag. You do not need the physical notice to renew — it is straightforward a convenience.

Contact the Cobb County Tax Assessor's Office by phone or through their website if you have questions about your renewal fee, your vehicle record, or which Tag Office location is most convenient. They can also tell you whether your renewal has been processed if you renewed by mail and want to confirm receipt.

Contact the Tax Assessor's Office or visit a Tag Office to learn about registration requirements for out-of-state vehicles.

What if I sold my vehicle or it was totaled?

Can I renew someone else's tag for them?

Online renewal requires the tag number and VIN, which anyone with access to the vehicle can provide. In person, the vehicle owner or a person with power of attorney can renew at a Tag Office. By mail, anyone can mail in the renewal notice and payment on behalf of the owner.

What if my tag is damaged or the numbers are faded?

Visit a Tag Office in person with your vehicle and driver's license. They can issue a replacement tag. There may be a small replacement fee separate from your renewal fee. You do not need to wait for your renewal notice to replace a damaged tag.
