How to Register a Car in Arizona: Step-by-Step Process

What you need to register a car in Arizona

Arizona requires you to register your vehicle with the Department of Transportation (ADOT) Motor Vehicle Division before you can legally drive it on public roads. The process differs depending on whether you are registering a new vehicle, a used vehicle you just bought, or a vehicle you are moving to Arizona from another state.

For any registration, you will need proof of ownership (the title or bill of sale), proof of identity (driver's license or passport), and proof of Arizona residency (utility bill, lease, or mortgage statement dated within 60 days). You will also need to pass an emissions test if your vehicle is subject to Arizona's emissions program, which applies to most vehicles in Maricopa and Pima counties.

The registration fee varies based on your vehicle's age, weight, and type. ADOT charges a base registration fee plus an additional amount depending on your vehicle's dry weight. You can find the exact fee by using ADOT's online fee calculator before you go in, or you can call your local Motor Vehicle Division office.

Registering a vehicle you just bought in Arizona

If you bought a used vehicle from a private seller in Arizona, you will need the signed title (also called the certificate of title) from the seller. The seller must sign the back of the title and provide the odometer reading. You then sign as the new owner and bring the title to ADOT along with your ID and proof of residency.

If you bought the vehicle from an Arizona dealership, the dealership usually handles the title transfer and registration paperwork on your behalf. They will give you a temporary registration document (good for 30 days) so you can drive the vehicle home. You will receive your permanent registration in the mail within two to three weeks. Do not assume the dealership has completed everything—call them a few days before the temporary registration expires to confirm your permanent registration is on the way.

If you bought the vehicle from an out-of-state dealer or private seller, you will need to obtain an Arizona title first. Bring the out-of-state title, your ID, and proof of residency to ADOT. ADOT will issue you an Arizona title, and then you can register the vehicle using that new title.

Emissions testing before registration

Vehicles registered in Maricopa County (which includes Phoenix) and Pima County (which includes Tucson) must pass an emissions test before ADOT will issue registration. Vehicles in all other Arizona counties do not need an emissions test.

You can take your vehicle to any Arizona emissions testing station. The test costs between $20 and $30 and takes about 10 minutes. The testing station will give you a receipt showing whether your vehicle passed or failed. If your vehicle passes, bring the receipt to ADOT along with your other registration documents. If your vehicle fails, you will need to have it repaired and tested again before you can register it.

New vehicles (current model year) are exempt from emissions testing for their first registration in Arizona. Vehicles that are 25 years old or older are also exempt. If you are unsure whether your vehicle needs testing, call the testing station or ADOT before you go.

How to register in person at an ADOT office

Find your nearest Motor Vehicle Division office on ADOT's website. Bring your title or bill of sale, your valid ID, proof of Arizona residency, and your emissions test receipt (if required). If you are registering a vehicle you bought from a private seller, bring the signed title. If you are registering a vehicle you bought from a dealership, bring the paperwork the dealership gave you.

Walk up to the counter, give the clerk your documents, and tell them you want to register your vehicle. The clerk will verify your documents, calculate your registration fee, and process your registration. You will pay the fee at that time. You will receive a temporary registration document on the spot that is valid for 30 days. Your permanent registration (the sticker and registration card) will arrive in the mail within two to three weeks.

Wait times at ADOT offices vary by location and time of day. Offices are typically less busy early in the morning on weekdays. Some offices accept walk-ins only; others allow you to make an appointment online. Check your local office's website before you go.

Registering by mail or online

You can register your vehicle by mail if you have a current Arizona driver's license or ID card. Fill out Form 44-131 (process for Vehicle Registration), include a copy of your title, your emissions test receipt (if required), and a check or money order for the registration fee. Mail everything to the address listed on the form. Processing takes two to four weeks.

You can also register online through ADOT's website if you meet these conditions: you have a current Arizona driver's license or ID, your vehicle title is already in your name, and you are not registering a vehicle for the first time in Arizona. The online process takes about 10 minutes. You will pay the registration fee by credit or debit card. Your registration will be mailed to you within two to three weeks.

If you do not have an Arizona driver's license or ID yet, you must register in person at an ADOT office. You cannot use the mail or online options until you have an Arizona ID.

Registration fees and what affects the cost

Arizona registration fees are based on your vehicle's dry weight (the weight of the vehicle without fuel or cargo). The base registration fee is the same for all vehicles, but ADOT adds an additional amount per pound of dry weight. A lighter vehicle will cost less to register than a heavier one.

You can choose a one-year or two-year registration. A two-year registration costs more upfront but saves you money per year compared to renewing every year. Use ADOT's online fee calculator to enter your vehicle's weight and see the exact cost for one-year and two-year options.

Your vehicle's title or registration documents should list the dry weight. If you cannot find it, you can weigh your vehicle at a truck scale (usually found at quarries or recycling centers) and subtract about 50 pounds for fuel. Some ADOT offices can also look up the dry weight for you if you provide the vehicle's year, make, and model.

Registering a vehicle you moved to Arizona from another state

If you moved to Arizona and brought a vehicle registered in another state, you have 10 days to register it in Arizona. Bring your out-of-state registration and title, your Arizona driver's license or ID, and proof of Arizona residency to an ADOT office. ADOT will issue you an Arizona title and register your vehicle at the same time.

If your out-of-state vehicle is subject to Arizona's emissions program (Maricopa or Pima County), you will need to pass an emissions test before ADOT will register it. Schedule the test before you go to ADOT, or ask ADOT for a temporary registration so you can drive to the testing station.

Some states have different title requirements or lien holder information that may slow down the process. If ADOT tells you they need additional documents from your previous state, ask them to specify exactly what they need and where to send it. This usually takes one to two weeks.

Frequently Asked Questions

What if the title is in someone else's name?

If you bought the vehicle but the title is still in the seller's name, the seller must sign the back of the title and give it to you. You cannot register a vehicle in your name if the title is in someone else's name. If the seller refuses to sign the title, you may have a legal dispute; contact a local attorney or your state's attorney general office for guidance.

Can I register my vehicle online if I just moved to Arizona?

No. You must register in person at an ADOT office if you are registering a vehicle for the first time in Arizona, even if you have an Arizona driver's license. Once your vehicle is registered in Arizona, you can renew online in future years.

What happens if I drive without registering my vehicle?

Driving an unregistered vehicle in Arizona is a traffic violation. You can be stopped by police, fined, and required to show proof of registration. If you have a temporary registration from a dealership or ADOT, that is valid proof. If you do not have any registration document, you may face additional penalties.

How long does registration take if I go in person?

You will receive a temporary registration document on the spot that is valid for 30 days. Your permanent registration sticker and card will arrive in the mail within two to three weeks. Do not remove the temporary registration from your windshield until you receive the permanent sticker.

Can I register a vehicle that has a lien on it?

Yes. If you financed your vehicle through a bank or credit union, the lender's name will appear on the title as the lienholder. You can still register the vehicle; the lienholder's name does not prevent registration. The title will remain with the lender until you pay off the loan, at which point you can request a new title in your name only.
