IRP Washington State

The International Registration Plan (IRP) is a cooperative agreement among U.S. states, the District of Columbia, and Canadian provinces that streamlines the registration of commercial vehicles traveling across state and provincial lines. Instead of registering separately in every jurisdiction, carriers can obtain apportioned plates, which allow legal travel across multiple states and provinces.

Washington State participates in IRP, making it easier for carriers based in Washington to operate interstate or into Canada while maintaining compliance with a single registration system.

Who Needs IRP in Washington?

Not all commercial vehicles require IRP registration. In Washington, carriers must register if they operate a vehicle that:

• Has a gross vehicle weight (GVW) of 26,000 pounds or more, or
• Has three or more axles, regardless of weight, or
• Operates as part of a combination exceeding 26,000 pounds.

Both owner-operators and fleet carriers traveling outside Washington are required to register under IRP. Carriers that operate exclusively within the state are considered intrastate and do not need apportioned plates.

IRP Registration Process

IRP registration in Washington is handled by the Department of Licensing (DOL), Prorate and Fuel Tax (PRFT) Services Office. The process generally includes:

1. Completing the IRP application through Washington DOL.
   Submitting required documentation for your business and vehicles.
2. Paying apportioned registration fees, which are calculated based on miles traveled in each jurisdiction.
3. Receiving apportioned plates and cab cards for your fleet.

Washington offers the Prorate Online system, allowing carriers to file applications and manage registrations electronically, which simplifies the process and reduces paperwork. Accuracy is critical to avoid delays or errors in your registration.

Required Documents for Washington IRP

When applying for IRP in Washington, carriers typically need to provide:

• Proof of business in Washington (utility bills, lease agreements, or business licenses)
• Vehicle titles and ownership documents
• Proof of liability insurance meeting state requirements
• USDOT number and Federal Employer Identification Number (FEIN)
• Previous registration or IRP credentials (if renewing)
• Mileage records from the previous reporting period

Apportioned fees are paid to the Washington DOL, which then distributes them to other states or provinces based on your reported mileage.

Washington IRP Renewal & Deadlines

Washington state IRP registrations are valid for one year and must be renewed annually. Renewal notices are typically sent by the DOL before the expiration date, but it is the carrier’s responsibility to ensure timely filing.

To renew, carriers must submit updated mileage reports, provide any updated vehicle or business information, and pay renewal fees based on actual mileage traveled. Failure to file on time can result in penalties, suspension of registration, and the inability to operate legally across state and provincial borders. 

Washington IRP vs. IFTA

It’s important to distinguish IRP from other regulatory programs. IRP covers apportioned registration and license plates for interstate travel. 

IFTA (International Fuel Tax Agreement), by contrast, deals with fuel tax reporting. Carriers may also need UCR (Unified Carrier Registration) and Washington intrastate registration if operating within state lines. Typically, carriers operating interstate require both IRP and IFTA compliance.
