International Registration Plan

The International Registration Plan (IRP) is an agreement between member jurisdictions for registering vehicles that travel in two or more jurisdictions. The member jurisdictions include all contiguous states, the District of Columbia and participating Canadian provinces. Registrations issued under this agreement are commonly referred to as "apportioned" or "prorated" registrations.

Apportioned registration is an optional method of registration that provides for registration of a fleet of vehicles that operate in two or more jurisdictions, by payment of fees to the base jurisdiction. A fleet can include one or more vehicles. The base jurisdiction is responsible for transmitting the fees owed to the affected jurisdictions. Registration fees are determined by the percentage of miles traveled in each member jurisdiction and the registered combined gross vehicle weight rating (GVWR) of each vehicle.

For links to common IRP forms, documents and sites, go to the Quick and Related Links page.

Who Is Eligible?

You are eligible if your vehicle is a power unit that is used or intended for use in two or more IRP member jurisdictions and is used for the transportation of persons for hire or designed, used, or maintained primarily for the transportation of property, and your vehicle

  • has two axles and a GVWR or registered GVWR in excess of 26,000 pounds.
  • has three or more axles, regardless of weight.
  • is used in combination, when the GVWR of the combination exceeds 26,000 pounds.
What Are the Benefits?

With a single payment, you pay your registration fees for all the member jurisdictions you will be operating in during your registration period. The apportioned plate and cab card issued to each vehicle will be accepted as proof of registration in the member jurisdictions for which you registered. Rather than multiple plates and registration cab cards from each jurisdiction you register in, you receive only one license plate and a cab card from your base jurisdiction. You will not be required to purchase permits at the ports of entry for which you have paid registration fees. At any time, you have the ability to modify and update your registration to add or delete vehicles or jurisdictions to which you travel.
