Wisconsin IRP Plates

The International Registration Plan (IRP) is an agreement among U.S. states, the District of Columbia, and Canadian provinces that simplifies registration for commercial vehicles traveling across borders. Instead of carrying multiple state registrations, carriers can obtain IRP apportioned plates, which allow them to operate legally in all participating jurisdictions. Wisconsin is a member of IRP, and carriers based in the state who travel interstate must register under the plan.

With Wisconsin IRP plates, registration fees are fairly distributed among the states and provinces based on the actual miles your vehicles travel.

Who Needs Wisconsin IRP Plates?

IRP registration is required for:

Commercial vehicles with a gross vehicle weight (GVW) over 26,000 pounds.
Vehicles with three or more axles, regardless of weight.
Vehicle combinations (such as a truck and trailer) with a combined GVW over 26,000 pounds.

Both owner-operators and fleets traveling outside Wisconsin must obtain IRP plates.

IRP is not required for vehicles that weigh 26,000 pounds or less, have two axles, or operate only within Wisconsin. In addition, vehicles that are not used for hire and remain intrastate do not need apportioned registration.

IRP Registration Requirements

To apply for Wisconsin IRP plates, carriers typically need to provide:

Proof of business established in Wisconsin (such as a lease agreement, utility bill, or business license).
Vehicle titles and proof of ownership.
Proof of liability insurance that meets state requirements.
USDOT number and Federal Employer Identification Number (FEIN).
Previous registration documents (if renewing).
Mileage records from the prior reporting period.

How to Apply for Wisconsin IRP Plates

The IRP registration process in Wisconsin is managed through the Wisconsin Division of Motor Vehicles (DMV) Motor Carrier Services Section. The steps include:

Completing the IRP application with all required information.
Submitting the necessary documents and mileage data.
Paying apportioned fees, which are calculated based on the percentage of miles your fleet travels in each jurisdiction.
Receiving your apportioned plates and cab cards once your application is approved.

Wisconsin DMV also offers online services to make the filing process more convenient for carriers.

Renewal of IRP Plates

Wisconsin IRP plates are valid for one year and must be renewed annually. Carriers receive renewal reminders from the Wisconsin DMV, but it is the carrier’s responsibility to complete the renewal on time.

The renewal process requires submitting updated mileage reports, ensuring all vehicle and business documents are current, and paying the apportioned fees. Missing deadlines can result in fines, penalties, or even suspension of your IRP credentials, which can prevent you from operating legally across state or provincial lines.
