What you need to register a car in Washington

Washington car registration is handled by your county auditor's office, not a state DMV — each county runs its own vehicle licensing. To register a car, you need the vehicle's title (or a bill of sale if you just bought it), proof of ownership, a completed process form, and payment for registration fees. You can register in person at your county auditor's office, by mail, or online through some counties' websites.

The process takes about 15 minutes in person, or one to two weeks by mail. Your registration is valid for one year from the month you register, and you'll receive license plates and a registration card in the mail. Washington requires you to renew your registration every year, though you can do this online or by mail without visiting the office.

Key Takeaways

  • Your county auditor's office handles registration, not a state agency, so you'll contact the office in the county where you live.
  • You need the vehicle's title or bill of sale, proof of ownership, a completed form, and payment — bring originals and copies if registering in person.
  • Registration fees vary by vehicle type and county, so call your auditor's office or check their website for the exact cost before you go.
  • You can register online, by mail, or in person; online is fastest if your county offers it, but not all do.
  • Your registration expires one year from the month you register, and renewal reminders arrive by mail about 30 days before expiration.

Documents you need to bring or submit

Start with the vehicle's title. If you bought the car from a dealer or private seller, the title should be in your name or signed over to you. If you're registering a new vehicle, the dealer usually handles the first registration, but you may need to complete paperwork at the auditor's office. If you don't have the title yet, you can register with a bill of sale and a completed process; the auditor will issue a temporary registration while you wait for the title to arrive.

You'll also need proof of ownership — typically the title itself, or a bill of sale signed by the previous owner. Bring a photo ID to prove your identity. If someone else is listed on the title with you, both owners may need to sign the registration form, depending on how the title is worded. Check your county auditor's website or call ahead to confirm what counts as proof of ownership in your county, since requirements can vary slightly.

Complete the vehicle registration process before you go. Washington's form is called the "process for Vehicle Registration" (Form 14-003). You can read it from your county auditor's website or pick one up at their office. Fill in the vehicle identification number (VIN), make, model, year, and your personal information. If you're registering in person, you can often fill out the form at the office, but bringing it completed saves time.

Registration fees and what affects the cost

Washington registration fees depend on the vehicle's age, type, and weight. A standard passenger car typically costs between $30 and $50 for the first registration, though this varies by county. Trucks, motorcycles, and RVs have different fee schedules. Vehicles over 10 years old usually cost less than newer ones. Some counties add local fees on top of the state fee, so the total can be higher or lower depending on where you live.

You can find the exact fee for your vehicle by calling your county auditor's office or checking their website — most have fee calculators where you enter your vehicle's information. Bring cash, a check, or a debit card; not all offices accept credit cards. If you're registering by mail, include a check or money order with your process.

How to register in person at your county auditor's office

Find your county auditor's office online by searching "[your county] auditor vehicle registration" or visiting your county's official website. Office hours vary, but most are open Monday through Friday during business hours. Some larger counties have extended hours or Saturday appointments. Call ahead to confirm hours and whether you need an appointment, especially in busy urban counties.

Bring your title or bill of sale, proof of ownership, a photo ID, the completed process form, and payment. Hand these to the clerk, who will review them for completeness. If everything is in order, you'll pay the fee and receive a receipt. The auditor's office will mail your license plates and registration card within two to three weeks. You can drive the vehicle with your receipt until the plates arrive.

Registering by mail or online

To register by mail, read the process form from your county auditor's website, complete it, and mail it with copies of your title or bill of sale, proof of ownership, and a check or money order for the registration fee. Include a self-addressed stamped envelope if you want the receipt returned. Mail everything to the address listed on the form — each county has its own mailing address. Processing takes one to two weeks from the time the office receives your packet.

Online registration is available in some Washington counties through their auditor's website. You'll enter your vehicle information, upload images of your title and ID, and pay by debit or credit card. Not all counties offer this yet, so check your county auditor's website to see if it's available where you live. Online registration is usually the fastest option, with confirmation and temporary registration details sent by email the same day.

What happens after you register

After you register, the auditor's office mails your license plates and registration card to the address on your process. This takes two to three weeks. You can legally drive with your receipt until the plates arrive. Once they arrive, install them on the front and back of your vehicle — Washington requires both plates. Keep your registration card in your vehicle at all times; police can ask to see it during a traffic stop.

Your registration is valid for one year from the month you registered. About 30 days before expiration, you'll receive a renewal notice in the mail. You can renew online, by mail, or in person. Renewing online or by mail is simpler than the first registration because you don't need to bring your title again — just complete the renewal form and pay the fee. If you miss the expiration date, you can still renew, but you may owe a late fee.

Special situations: new vehicles, transfers, and address changes

If you buy a new vehicle from a dealer, the dealer usually registers it for you as part of the sale. You'll receive the plates and registration card in the mail. If you buy from a private seller, you handle the registration yourself using the bill of sale and the seller's signed title. You have 15 days from the purchase date to register the vehicle in Washington.

If you move to a different county within Washington, you don't need to re-register your vehicle — your current registration remains valid. However, if you move out of state, you'll need to register in your new state. If you change your address within Washington, update it with your county auditor when you renew your registration, or submit a change-of-address form at any time.

If you sell your vehicle, notify your county auditor in writing or online (if available) to cancel the registration. This protects you from liability if the new owner is in an accident. The new owner will register the vehicle in their name using the title you signed over to them.

Frequently Asked Questions

Can I register a car online in Washington?

Some Washington counties offer online registration through their auditor's website, but not all. Check your county auditor's website to see if the option is available where you live. If it is, you can complete the entire process online, upload documents, and pay by card — usually the fastest method.

What if I don't have the title yet?

You can register with a bill of sale and a completed process form. The auditor will issue a temporary registration while you wait for the title to arrive from the previous owner or the dealership. Once you receive the title, you may need to submit it to the auditor to complete the registration.

How long does registration take if I mail it in?

Processing by mail typically takes one to two weeks from the date the auditor's office receives your packet. Mail your process early to avoid delays. Include a self-addressed stamped envelope if you want your receipt returned, and keep a copy of everything you send for your records.

Do I need to register my car every year in Washington?

Yes, Washington requires annual registration renewal. You'll receive a renewal notice by mail about 30 days before your registration expires. You can renew online, by mail, or in person — you don't need to bring your title again for renewal, just the renewal form and payment.

What if I buy a vehicle from out of state?

You have 15 days from the purchase date to register it in Washington. Bring the out-of-state title, bill of sale, proof of ownership, and payment to your county auditor's office. If the title is from another state, the auditor will process it and issue a Washington title and registration.
