Where to register your vehicle in DeKalb County

You register your car at the DeKalb County Tax Assessor's office, not at a separate DMV location. The Tax Assessor handles all vehicle registration for the county. You can register in person at their main office in Decatur, or you can mail in your documents if you prefer not to visit in person.

The main office is located at 556 North McDonough Street, Decatur, GA 30030. They are open Monday through Friday, 8:30 a.m. to 4:30 p.m., and closed on weekends and county holidays. If you live in a different part of DeKalb County, this is still the office you'll use — there are no satellite locations for registration.

Before you go or mail anything, gather your documents. You'll need your current out-of-state registration (if you're new to Georgia), proof of a Georgia vehicle inspection, proof of insurance, and a form of identification. If someone else owns the vehicle, you'll also need a power of attorney or the owner's signed consent.

  • Registration by mail is an option if you submit all required documents and include a check or money order for the registration fee.
  • Your registration is valid for one year from the date issued, and you'll receive renewal notices by mail about 30 days before expiration.
  • If you're registering a vehicle for the first time in Georgia, bring your out-of-state title and registration along with your inspection and insurance proof.

What documents you need to bring or mail

The Tax Assessor's office requires a specific set of documents for registration. Start with proof of a Georgia vehicle inspection — this must be completed within 12 months of your registration date. You can get an inspection at any Georgia-certified inspection station; they are independent businesses, not run by the county. The inspection costs vary but typically run $20 to $30.

Next, bring proof of insurance. This can be your insurance card, a declaration page from your insurance company, or a letter from your insurer showing your policy number and coverage dates. The insurance must be active on the date you register. You'll also need a valid form of identification — a driver's license, passport, or state ID card all work.

If this is your first registration in Georgia, bring your current out-of-state registration and your vehicle title. If you're renewing a Georgia registration, you'll need your renewal notice (which arrives by mail) or your current registration card. If someone else owns the vehicle, bring a signed power of attorney from the owner, or a notarized letter giving you permission to register on their behalf.

Registration fees and what they cover

DeKalb County registration fees depend on your vehicle's weight and age. The Tax Assessor's office calculates the fee based on the vehicle's gross vehicle weight rating (GVWR), which is listed on your vehicle's door jamb or in your owner's manual. Fees typically range from $20 to over $200 for standard passenger vehicles, but the exact amount varies.

You can call the Tax Assessor's office at 770-413-4500 to ask about your specific vehicle's fee before you go in. They can calculate it over the phone if you give them your vehicle's make, model, year, and GVWR. This saves you a trip if the fee is higher than you expected or if you need to budget for it.

Your registration fee covers your registration for one year from the date it's issued. You do not pay separate inspection or title fees at registration — the inspection fee goes to the inspection station, and title fees (if you need a new title) are handled separately. When your registration expires, you'll receive a renewal notice in the mail about 30 days before the expiration date.

How to register by mail

If you don't want to visit the office in person, you can mail your documents to the Tax Assessor. Send your inspection certificate, proof of insurance, a copy of your identification, your current registration or renewal notice, and a check or money order for the registration fee to 556 North McDonough Street, Decatur, GA 30030.

Include a cover letter with your name, phone number, vehicle identification number (VIN), and the make and model of your vehicle. This helps the office match your documents to your vehicle. Mail registration typically takes two to three weeks to process, so send your documents well before your current registration expires.

If you're unsure about the fee amount, call 770-413-4500 before mailing. You can also ask whether they prefer a check or money order. If your fee is incorrect, they will contact you, and you may need to send an additional payment or wait for a refund — this delays your registration, so getting the amount right the first time is worth the phone call.

Getting a Georgia vehicle inspection

Before you can register, you must have a current Georgia vehicle inspection. This is not done by the Tax Assessor — you go to any Georgia-certified inspection station. These are independent repair shops and service stations that have been certified by the state to perform inspections. You can find one by searching online for "Georgia vehicle inspection near me" or asking your mechanic if they perform inspections.

The inspection checks your brakes, lights, horn, windshield wipers, seat belts, and emissions (for vehicles in certain counties). The inspection takes about 15 to 30 minutes and costs $20 to $30. Once passed, you receive an inspection certificate with a sticker that goes on your windshield. The inspection is valid for 12 months from the date it's completed.

You do not need to schedule an inspection in advance at most stations — you can walk in or drive in during business hours. However, some busy locations may have wait times, so calling ahead is a good idea if you're in a hurry. Bring your vehicle keys and your vehicle registration or title so the inspector can verify the VIN.

Renewing your registration

Your registration expires one year from the date it was issued. About 30 days before expiration, you'll receive a renewal notice in the mail from the Tax Assessor. The notice includes your renewal fee amount and instructions for renewing by mail or in person.

To renew, you need a current Georgia vehicle inspection (completed within 12 months) and proof of insurance, just like initial registration. You do not need to bring your title again unless you're changing ownership or the vehicle information. You can renew in person at the Tax Assessor's office or by mail using the same process as initial registration.

If you miss your renewal date, your registration becomes expired. You can still renew, but you should do so as soon as possible — driving with an expired registration can result in a traffic stop and a fine. If your renewal notice doesn't arrive, contact the Tax Assessor's office to confirm your address is correct in their system.

What happens after you register

Once your registration is processed, you'll receive a registration card and a license plate sticker (or a new plate if you're registering for the first time in Georgia). If you registered in person, you may receive these on the same day. If you registered by mail, they arrive within two to three weeks.

Attach the license plate sticker to your existing plate, or install the new plate on your vehicle if one was issued. Keep your registration card in your vehicle — you're required to show it to a police officer if you're stopped. Your registration is now active and valid for one year.

If you move to a different address within DeKalb County, you don't need to re-register — your registration stays valid. If you move out of DeKalb County or out of Georgia, you'll need to register in your new location. If you sell your vehicle, the new owner will need to register it in their name.

Frequently Asked Questions

Can I register my car online?

DeKalb County does not offer online registration through the Tax Assessor's website. You must register in person at the office or by mail. Some states offer online renewal, but Georgia does not currently have this option for DeKalb County residents.

What if I just moved to DeKalb County from another state?

Bring your out-of-state registration, your vehicle title, a Georgia inspection certificate, proof of insurance, and your ID. You'll register as a new vehicle in Georgia, not as a renewal. The process is the same, but you'll need your title to prove ownership.

Do I need to register if I'm only visiting DeKalb County temporarily?

No. If you're visiting and your out-of-state registration is current, you can drive legally in Georgia for up to 30 days. If you stay longer or move to Georgia permanently, you must register within 30 days of establishing residency.

What if my inspection expires before my registration does?

Your registration remains valid, but you cannot legally drive the vehicle without a current inspection. You must get a new inspection before your current one expires. When you renew your registration, you'll need to show proof of a current inspection.

How do I contact the Tax Assessor's office if I have questions?

Call 770-413-4500 during business hours (Monday through Friday, 8:30 a.m. to 4:30 p.m.). You can also visit in person at 556 North McDonough Street, Decatur, GA 30030, or check the DeKalb County website for additional contact options and forms.
