What ADOT handles and where to start
Arizona Department of Transportation (ADOT) is the state agency that issues vehicle registrations, handles renewals, and manages the documents you need to legally drive in Arizona. If you own or lease a vehicle in Arizona, ADOT is where your registration comes from — not your county, not your insurance company, and not a third-party service.
You can handle most registration tasks through ADOT's online portal at servicearizona.com, in person at an ADOT office, or by mail. The fastest route for renewals is usually online, which takes a few minutes and costs nothing extra. New registrations, title transfers, and address changes have different requirements and timelines.
ADOT also manages vehicle titles (proof of ownership), emission testing coordination, and special plates like disabled veteran or personalized plates. Understanding which ADOT service you actually need saves time and prevents delays.
Key Takeaways
- ADOT registration renewals can be completed online at servicearizona.com in minutes, and you receive your new registration by mail within two weeks.
- New vehicle registrations require a title document, proof of insurance, and an ADOT form completed in person or by mail — online is not an option for new registrations.
- ADOT offices are located in Phoenix, Tucson, and several other cities, but you can renew by mail or online without visiting in person.
- Your registration expires on the date printed on your current registration card, and ADOT sends renewal notices by mail about 60 days before expiration.
- Emission testing is required for vehicles in Maricopa and Pima counties; ADOT coordinates the testing network but does not perform the tests itself.
Renewing your registration online or by mail
Online renewal through servicearizona.com is the fastest method. You log in with your Arizona driver's license number and date of birth, confirm your vehicle information, pay the renewal fee, and receive a confirmation email. Your new registration card arrives by mail in 7 to 14 days. The fee varies based on your vehicle's weight and age; ADOT's website shows the exact amount before you pay.
You can renew online only if your vehicle information has not changed, your insurance is current, and you have no outstanding violations or liens on the title. If any of those conditions do not explore, you must renew by mail or in person.
Mail renewal requires the renewal notice ADOT sends you, a check or money order, and a completed form. Mail your packet to the ADOT address listed on your renewal notice. Processing takes 2 to 3 weeks from the date ADOT receives it, so send it at least 30 days before your registration expires.
Registering a new vehicle or one you just bought
New vehicle registrations cannot be done online. You need the vehicle's title document, proof of insurance from an Arizona-licensed insurer, and ADOT form REG 130 (process for Vehicle Registration). You can complete the form online at servicearizona.com and print it, then submit it in person at an ADOT office or by mail with your title and insurance proof.
If you bought the vehicle from a dealer, they often handle the registration paperwork for you and charge a processing fee. If you bought it privately, you are responsible for submitting the paperwork. The title must show you as the new owner, which requires the seller to sign it over to you before you submit anything to ADOT.
Processing a new registration takes 2 to 4 weeks by mail. In person at an ADOT office, you can sometimes receive a temporary registration the same day while your permanent card is mailed to you.
ADOT office locations and hours
ADOT has a main office in Phoenix and satellite offices in Tucson, Mesa, Chandler, Glendale, Tempe, and several other cities. Hours vary by location, but most are open Monday through Friday, 8 a.m. to 5 p.m., with some locations offering limited Saturday hours. You do not need an appointment at most offices, but wait times can be 30 minutes to over an hour during peak times (mid-morning and mid-afternoon on weekdays).
Before visiting an office, check the ADOT website for your nearest location and current hours, since some offices have adjusted their schedules. You can also call ahead to ask about current wait times.
Emission testing requirements and coordination
If your vehicle is registered in Maricopa County (Phoenix area) or Pima County (Tucson area), you must pass an emission test every two years as part of registration renewal. ADOT does not perform the tests; instead, it coordinates with private testing stations throughout the state.
You can find a testing station near you on the ADOT website. The test costs between $20 and $30 and takes about 10 minutes. You receive a certificate of compliance, which you then submit to ADOT as part of your renewal. If you renew online, you can upload the certificate; if you renew by mail, you include it with your paperwork.
If your vehicle fails the emission test, you have the option to repair it and retest, or in some cases to request a waiver from ADOT if repairs would cost more than a certain threshold. ADOT publishes the current waiver threshold on its website.
Transfers, address changes, and special situations
If you move to a new address in Arizona, you can update it online at servicearizona.com without renewing your registration early. If you move out of Arizona, you must cancel your registration with ADOT and register your vehicle in your new state.
If you sell your vehicle, the buyer is responsible for registering it in their name. You should notify ADOT that you no longer own the vehicle to avoid liability for traffic violations or accidents. You can do this by submitting form REG 142 (Notice of Sale or Transfer) by mail or in person.
If your vehicle has a lien (the lender holds the title), you cannot transfer ownership until the lien is released. Once the lender releases the lien, they send you the title, and you can then register the vehicle in your name or transfer it to a new owner.

Frequently Asked Questions
Can I renew my registration if it has already expired?
Yes. ADOT allows you to renew a registration up to one year after it expires. However, you should not drive the vehicle with an expired registration — doing so is a traffic violation. Renew as soon as you realize it has expired, and keep proof of your renewal process with you while you wait for your new card to arrive.
What happens if I lose my registration card?
You can request a replacement card from ADOT by submitting form REG 141 (process for Duplicate Registration Card) in person or by mail. The fee is typically $5 to $10. You can drive legally while waiting for the replacement as long as you can show proof that you submitted the request.
Do I need to register my vehicle in Arizona if I just moved here?
Yes. Arizona law requires you to register any vehicle you own within 30 days of establishing residency. If you have an out-of-state registration, you must surrender it and register the vehicle with ADOT. You will need your current out-of-state title, proof of insurance, and a completed ADOT form.
Can someone else renew my registration for me?
Yes. You can authorize someone else to renew your registration by mail or in person at an ADOT office. They will need your renewal notice, payment, and a signed letter from you authorizing them to act on your behalf. Online renewal requires your personal login, so you cannot authorize someone else to do it that way.
What if my vehicle has a salvage or rebuilt title?
Vehicles with salvage or rebuilt titles can be registered in Arizona, but the process is different from standard registration. You must submit additional documentation proving the vehicle has been repaired and inspected. Contact ADOT directly or visit an office to learn what documents your specific vehicle needs, as requirements vary based on the vehicle's history.
