Cobb County facts
Cobb County sits northwest of Atlanta and holds Marietta as its county seat. The county counted 766,149 people in the 2020 Census, which makes it the third most populous county in Georgia. It covers about 345 square miles of dense suburbs, office corridors, and historic town centers.
The county dates to 1832, formed from Cherokee lands after the state land lottery. Georgia named it for Thomas Willis Cobb, a U.S. congressman and senator. Marietta grew around the railroad and the county square, and Kennesaw Mountain still marks the Civil War history written across its northern half.
Five counties border Cobb County: Cherokee, Fulton, Douglas, Paulding, and Bartow. Drivers near a county line should register where they live and where the car stays overnight. Your home address picks your tag office.
Tag office locations, hours, and contact
The Cobb County Tax Commissioner runs four full-service tag offices. Pick the one nearest you. All four handle plates, titles, and renewals in person.
- North Marietta (main). 2932 Canton Road, Suite 300, Marietta, GA 30066. Phone 770-528-8600. Open Monday through Friday, 8:00am to 5:00pm.
- South / Austell. Serves Austell, Mableton, and Powder Springs drivers. Check the county site for the current address and hours before you drive over.
- East Marietta. Serves east Marietta and Smyrna-area drivers. Check the county site for the current address and hours before you drive over.
- West / Acworth. Serves Acworth and Kennesaw-area drivers. Check the county site for the current address and hours before you drive over.
Self-service tag kiosks renew tags 24 hours a day, seven days a week. The kiosk prints your new decal on the spot. Bring your renewal notice or plate number and a card for payment.
Online renewal runs through cobbtax.org. Most drivers never need a counter visit. Renew online, and the decal arrives by mail within days.
What to bring to the tag office
Bring the right papers and most visits take under 30 minutes. Missing papers cause most delays. Gather these before you leave home.
- Vehicle title or title application. New purchases need the signed-over title or the dealer's title paperwork. Moves from another state need the current out-of-state title.
- Valid photo ID. A Georgia driver's license or state ID works. New residents can use their out-of-state license during the move-in window.
- Proof of Georgia insurance. The policy must be active and list the vehicle. The state checks coverage by computer, so bring the card as backup.
- Emissions test report. Cobb County requires a passing test for most cars at renewal. Test first, then renew.
- Payment. The offices take standard payment methods. Card payments may add a small processing fee.
Drivers with a lienholder should bring the lienholder's full name and mailing address, so the state can record the lien on the new Georgia title. New residents should bring a Georgia address proof such as a lease or utility bill along with the out-of-state title and ID. Leased cars need the lease agreement plus the leasing company's title details.
Steps to register your vehicle, transfer a title, and renew tags at the counter
To register a motor vehicle, transfer an out-of-state title, or replace registration credentials at the Cobb County tag office, follow these steps during your counter visit:
- Document Pre-Verification — Gather the original certificate of title or Manufacturer's Certificate of Origin (MSO), signed bill of sale, valid Georgia driver's license or state ID card reflecting your Cobb County residence, proof of active Georgia auto liability insurance (transmitted to GEICS by your insurer), and a passed Georgia vehicle emissions inspection report (mandatory for Cobb County as one of Georgia's 13 Clean Air Force metro counties).
- Service Intake & Queue Assignment — Report to 2932 Canton Road, Suite 300, Marietta, GA 30066. Check in at the customer intake kiosk or reception counter to obtain a service queue number for Title & Registration transactions.
- Document Examination & VIN Audit — When your queue ticket is called, present your documents to the deputy tax commissioner clerk. The clerk reviews odometer disclosures, verifies bill of sale signatures, checks for existing liens, and verifies electronic liability insurance verification in the state portal.
- Statutory Assessment & Fee Remittance — The clerk calculates the statutory charges: one-time 7.0% Title Ad Valorem Tax (TAVT) based on Georgia Department of Revenue vehicle assessment schedules (or purchase price, whichever is higher), the $18.00 state title application fee, and the $20.00 standard annual tag fee. Payment may be tendered via cash, personal check, certified funds, or debit/credit card.
- Immediate Decal & Metal Plate Issuance — Upon payment processing, the clerk issues your metal Georgia license plate, Cobb County county name strip, and color-coded validation decal displaying your birth month and expiration year. Affix the metal plate to your rear bumper before driving on public highways and keep the paper registration certificate in your vehicle glovebox.

Fees and title tax details in Cobb County
Georgia sets tag fees at the state level, so the core costs match every other county. The big number is the title ad valorem tax.
Title ad valorem tax (TAVT) applies when you title a car in Georgia for the first time, at a rate of 7.0% of the car's fair market value. Buyers pay it at purchase, and new residents pay it when they register their out-of-state car here. A $20,000 car brings a $1,400 bill, but a $10,000 car brings $700.
Out-of-state cars get valued from standard pricing data at first titling, and the county uses that value to set the 7.0% tax. A clean low-mileage car costs more to title than a rough high-mileage one, since the tax follows value rather than looks. Title tax has no payment plan at the counter, so bring full payment or expect a card processing fee on a large charge.
Standard tag fees stay low. A regular plate costs $20, and yearly renewal adds a small tag fee. Prestige plates cost $90 plus ad valorem tax to start and $55 plus ad valorem tax each year to keep the custom text. Specialty plates run about $55 per year on top of the base cost.
Late penalties grow fast. Georgia ties renewal month to the owner's birthday, and driving on an expired tag can bring fines far above the renewal cost. Renew early in your birthday month.
Plate choices for Cobb County drivers
Every Georgia county offers the same plate types. Your county does not limit your choices. Pick what fits your car and budget.
The standard plate is the default choice, carrying the ABC1234 format Georgia has used since May 2012. It costs $20, and most drivers keep it for the life of the car.
Prestige plates carry custom letters and numbers you choose, at $90 plus ad valorem tax to start and $55 plus ad valorem tax per year to keep the text. Prestige plate requests go through a state review, and staff reject letter combos that break state rules or mimic official plates.
Specialty plates support colleges, sports teams, military groups, and causes, with yearly fees around $25 above the base tag cost. Specialty plate money splits between state costs and the cause on the plate, so your yearly fee funds both the program and the plate itself.
Order any plate type at a Cobb tag office or through the DRIVES portal. Standard plates leave with you the same day. Talk to the clerk if you are torn between plate types. The staff see every option daily and can explain the cost difference in plain terms.
Renew on your birthday
Georgia ties tag renewal month to the owner's birthday, so your tag expires on your birthday each year. Mark the month and renew early.
Cobb County drivers can renew four ways. The county's online site at cobbtax.org is the fastest option for most people. The DRIVES portal handles most renewals in minutes. Kiosks print decals on the spot, day or night. You can renew by mail or visit any of the four offices in person.
Business-owned cars and leased fleets follow different renewal schedules, so fleet managers should confirm their dates with the county. Late renewals add penalties, and driving on an expired tag risks a ticket. Set a phone reminder for the first week of your birthday month.
Emissions testing in Cobb County
Cobb County requires emissions testing. It sits inside the 13-county metro Atlanta testing zone, along with Cherokee, Clayton, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale. Most gasoline cars between 3 and 25 model years old need a passing test each year before renewal.
The test takes about 15 minutes at a certified station. The station plugs into your car's diagnostic port and checks that the emissions system works as built. The fee runs about $25, and you pay the station directly. Keep the passing report, since the tag office checks it at renewal.
If your car fails, fix the flagged parts and retest. Georgia allows a repair waiver in some cases after you spend a set amount on real repairs, so ask the station about waiver rules before you pay for a second test. New cars under 3 model years old skip the test, and cars 25 years or older skip it as well.
Drivers who move from outside the zone into Cobb County pick up the testing rule. The rule follows the county where the car is registered. Test before your first Cobb renewal to avoid a wasted trip.
New to Cobb County?
New Georgia residents must register their cars within 30 days of moving in or starting work here. Start the 30-day clock on the day you move in or start a Georgia job, whichever comes first. Weekends count, so do not wait for a free Saturday.
Bring your out-of-state title, proof of Georgia insurance, and a valid ID to any Cobb tag office. You will pay the 7.0% title ad valorem tax on the car's value plus tag fees, and Georgia titles the car in your name and issues a Georgia plate. Keep your out-of-state registration card until the Georgia title arrives, in case questions come up about the transfer.
Take the old state's plate off once the Georgia plate is on. Never drive with two plates. Military members follow different rules, so ask the tag office about military options before you pay standard fees. Ask the clerk about the fastest way to get your Georgia driver's license too, since the tag office does not handle licenses. Many new residents handle the license at Driver Services first, then bring the new license to the tag office.
Dealer purchase vs. private purchase
Buy from a licensed Georgia dealer and the dealer handles the title paperwork for you. The dealer collects the 7.0% title ad valorem tax, files the title application with Cobb County, and hands you a 30-day paper temp tag at sale. Your metal plate arrives by mail once the county processes the filing.
Buy from a private seller and the job falls on you. Both buyer and seller sign the title over, the buyer brings the signed title to a Cobb tag office, and the county issues the title and plate. Private sales need a bill of sale that lists the price, the date, and the full names of buyer and seller.
Never accept a title with open liens or missing signatures. Problems on the title become your problems at the counter. Watch the temp tag date on dealer purchases, and call the dealer first if your metal plate runs late.
Lost, stolen, or damaged plates
Report a stolen plate to local police first, then bring the report number to the tag office for a replacement. Damaged plates need no police report. Bring the bent or faded plate to any Cobb office and the clerk issues a replacement.
Replacement plates cost a few dollars plus the new decal fee. The plate number may change, so update your insurance card after a replacement. Keep the old registration card until the new one arrives. Drive with the replacement plate mounted on the rear.

What the tag office cannot do
Cobb tag offices handle plates, titles, and renewals. Some tasks sit outside their walls. Know the limits before you visit.
It cannot share who owns a plate. Federal privacy law shields owner names and addresses, and only police, courts, and parties with a valid legal claim can get that data. No walk-in request unlocks it.
It cannot issue driver's licenses. Licenses come from the Georgia Department of Driver Services, a separate agency with its own offices. Do not bring license tasks to the tag counter.
It cannot clear court holds. Tickets and court cases go through the court named on the ticket, and the tag office cannot lift a hold until the court clears it.
What happens if your tag expires
An expired tag makes every drive a risk. Police can ticket you at any traffic stop, and the fine tops the renewal cost fast. Some drivers learn this at a roadside stop. Do not be one of them.
You cannot renew online once the tag lapses past a point, so late drivers often must visit the office in person. Penalties add to the base renewal fee each month you wait. The longer you delay, the larger the total grows. Renew on time and the whole process costs the base fee plus minutes of your day.
An expired tag can freeze other car tasks. You cannot transfer a title or order a specialty plate until the renewal is current. If your car sits unused, you still owe renewal to keep the registration active. Surrender the plate to the county if you take the car off the road for good.
It cannot value your car over the phone. The state sets values from pricing data, and the counter staff cannot change the number.
It cannot backdate a renewal to skip penalties. The system stamps the actual date, so late fees apply from the deadline.
A simple yearly routine
Check your birthday month. That is your renewal month. Get the emissions test first. Renew online through the county site. Print your receipt. Wait for the decal in the mail. Stick it on your plate. Done.
If you move, update your address fast. If you sell the car, keep your plate. If you buy a car, title it within days. Small habits beat big fines. Check the decal each January. A faded decal is hard to read. Replace it before police notice. Keep this page bookmarked for hours.

Cobb County Tag Office: Frequently Asked Questions

Where is the Cobb County tag office?
The main Cobb County tag office is at 2932 Canton Road, Suite 300, Marietta, GA 30066. That is in Marietta, the county seat, and it handles every tag and title task for Cobb County drivers. Call 770-528-8600 if you need directions before you drive over. Staff answer most fee questions by phone. Call first. More offices and self-service kiosks cover other parts of the county.
What are the Cobb County tag office hours?
Mon-Fri 8:00 AM - 5:00 PM. It pays to ring 770-528-8600 before you head out, since small offices can shift hours without notice. Weekends and county holidays are closed. Plan ahead.
Do I need an emissions test in Cobb County?
Yes. Cobb County sits in Georgia's 13-county metro Atlanta emissions testing zone. A certified station runs an OBD check on most gas cars and light trucks, and the result stays valid for 12 months. Plan on about $25, then renew with a passing result in hand.
What should I bring to the Cobb County tag office?
Bring your title, Georgia insurance card, and photo ID, since the clerk will ask for all three at the counter. A new purchase needs a bill of sale, and a financed car needs a lien release or lienholder letter. Missing papers mean a second trip.
How much is the title tax (TAVT) in Cobb County?
The title tax is one-time. Georgia charges 7% of the car's fair market value at the time the title first moves into your name. A $10,000 car means about $700 in TAVT. That is it.
Can I renew my Cobb County tag without visiting the office?
Yes, in most cases. Most Cobb County drivers can renew through the county's online tax payment site or the state DRIVES portal these days. Self-service tag kiosks give you another fast option. Have your plate number or renewal notice ready.
