You need plates from your state's motor vehicle agency, and the timing depends on whether you buy from a dealer or private seller

If you buy from a dealer, they usually handle the paperwork and send it to your state's motor vehicle department on your behalf. You'll get temporary plates to drive home, then permanent plates arrive by mail within two to eight weeks depending on your state. If you buy from a private seller, you handle the registration yourself — you'll need the signed title, proof of insurance, and a completed registration form, which you submit to your state's motor vehicle agency in person or by mail.

The process is faster at a dealership because they're set up to file everything at once. Private sales require you to do the legwork, but the cost is usually lower. Either way, you cannot legally drive without some form of plates or temporary registration from the moment you take possession.

Key Takeaways

  • Dealerships file your registration paperwork with the state and issue temporary plates on the spot; you drive home legally while permanent plates are made.
  • Private sales require you to bring the signed title, proof of insurance, and a completed registration form to your state's motor vehicle agency yourself.
  • Temporary plates are valid for a set period (usually 30 to 90 days depending on your state) and must be replaced with permanent plates before they expire.
  • Permanent plates take two to eight weeks to arrive by mail after your registration is processed, so plan to drive on temporary plates for at least that long.
  • You must have proof of insurance before you register — most states require it on the process form itself.

What happens at a dealership

When you buy from a dealer, the sales staff will give you a packet of paperwork that includes the vehicle's title (or a temporary document if the title is being transferred), a registration process, and proof of sale. The dealer's finance or administrative office files this with your state's motor vehicle agency, usually the same day or within a few business days. You leave the lot with temporary plates — either a paper tag you tape to the rear window or metal plates with a temporary registration sticker.

Temporary plates are legal to drive on when ready. They're valid for a fixed period set by your state, typically 30 to 90 days. During this time, your permanent plates are being manufactured. Once they're ready, the state mails them to the address on your registration. You install them yourself when they arrive — no trip back to the dealer needed. Keep your temporary plates or registration document in the car until the permanent ones show up, in case you're stopped by police.

The dealer may charge a documentation or processing fee (sometimes called a "doc fee"), which covers their cost of filing. This is separate from registration fees charged by the state. Ask the dealer for an itemized breakdown before you sign, so you know what you're paying for.

What you need to do for a private sale

When you buy from a private seller, you become responsible for registration. Before you drive the car home, make sure the seller signs the title in the correct place — titles have specific signature lines for the seller and buyer, and signing in the wrong spot delays everything. Ask the seller to sign in front of you so there's no confusion later. You'll also need the seller's printed name and address on the title.

Next, get proof of insurance. You cannot register a car without it in any state. Call an insurance agent or go online and buy a policy before you go to the motor vehicle agency. The policy must be active and cover the specific vehicle (use the vehicle identification number, or VIN, from the title). Print or read proof of insurance — most insurers email it when ready.

Then go to your state's motor vehicle agency with the signed title, proof of insurance, a completed registration process (read it from your state's website or pick one up at the agency), and a valid ID. Bring your payment method — registration fees vary by state and sometimes by vehicle weight or age. The agency will process your process, collect the fee, and issue you temporary plates or a temporary registration document. Permanent plates arrive by mail in two to eight weeks.

Temporary plates and how long they last

Temporary plates or temporary registration documents are your legal proof that you can drive while permanent plates are being made. They're not optional — you must have one or the other from the moment you take possession of the car. Driving without temporary plates or permanent plates is illegal and can result in a fine.

How long temporary plates last depends on your state. Some states issue 30-day temporary plates, others 60 or 90 days. Check your temporary registration document or ask the dealer or motor vehicle agency staff when yours expire. Mark the date on your calendar. If permanent plates haven't arrived by the expiration date, contact your state's motor vehicle agency to request a renewal of your temporary registration — most states allow one or two renewals by phone or online.

Once permanent plates arrive, remove the temporary plates or sticker and install the permanent ones. Keep the temporary document in your glove box for a few weeks in case you're pulled over and the officer wants to see proof of registration. After that, you can discard it.

Registration fees and what they cover

Registration fees are set by your state and vary widely. Some states charge a flat fee; others charge based on the vehicle's age, weight, or value. A new car in one state might cost $150 to register, while the same car in another state costs $400. Check your state's motor vehicle website for the exact fee before you go in.

Registration fees cover the cost of manufacturing and mailing your plates, processing your paperwork, and maintaining the state's vehicle database. Some states also bundle in a small portion of road maintenance funding. The fee is separate from sales tax (which you pay to the dealer or at the time of purchase) and separate from any documentation fees a dealer charges.

If you're registering a vehicle you bought out of state, your home state will charge you registration fees based on your state's rates, not the state where you bought it. Some states also charge a one-time title transfer fee in addition to registration. Ask your motor vehicle agency whether title transfer and registration are one fee or two.

What to do if something goes wrong

If you don't receive permanent plates within the timeframe your state quoted (usually eight weeks), contact your state's motor vehicle agency. Have your registration number or VIN ready. They can tell you whether the plates have been mailed and provide a tracking number, or they can reissue them if there was a problem. This usually takes a few days to a week.

If the title has errors — a misspelled name, wrong VIN, or signature in the wrong place — the motor vehicle agency will reject your registration. You'll need to get the title corrected. If the seller made the error, they have to sign a correction form or explore for a corrected title from their state. If you made the error, you may be able to correct it at the motor vehicle agency, but this varies by state. Call ahead to ask what documents you need to bring.

If you lose your temporary plates or registration document before permanent plates arrive, go back to the dealer (if you bought from a dealer) or the motor vehicle agency (if you bought privately) and request a replacement. Bring your ID and proof of purchase. There may be a small replacement fee.

Renewing plates and keeping registration current

Once you have permanent plates, they're yours for as long as you own the car in that state. However, your registration expires annually or every two years depending on your state. Your state will mail you a renewal notice before the expiration date. You renew by paying the registration fee again — either by mail, online, or in person at the motor vehicle agency. When you renew, you'll receive a new registration sticker to put on your plates, or in some states, a new registration document.

If you move to a different state, you'll need to register your car in your new state and get new plates. The process is the same as registering a car you just bought — bring the title, proof of insurance, and a completed registration form to your new state's motor vehicle agency. Your old plates become invalid once you register in the new state.

Frequently Asked Questions

Can I drive home from the dealer without plates?

No. The dealer must give you temporary plates or a temporary registration document before you leave the lot. If they don't, do not drive the car — it's illegal. Ask the sales staff for your temporary plates before you sign the final paperwork.

What if the seller won't sign the title?

Do not buy the car. A title must be signed by the seller to transfer ownership. If the seller refuses or delays, they may not actually own the car or may have a lien against it. Walk away and find a different vehicle.

Do I need to go back to the motor vehicle agency after I get permanent plates?

No. Once permanent plates arrive by mail, install them yourself and you're done. You don't need to return to the agency or notify them. Keep your registration document in the car.

How much does registration cost?

Registration fees vary by state and sometimes by vehicle type. They typically range from $100 to $400 for a new car, but some states charge more. Check your state's motor vehicle website or call their office for the exact fee before you register.

What if I buy a car in one state and move to another before I get permanent plates?

Contact the first state's motor vehicle agency and ask them to mail your permanent plates to your new address, or cancel the registration and register in your new state instead. Most states allow address changes by phone or online. If you register in your new state, you'll get new plates from that state.
