What is Apportioned Registration?
Apportioned Registration, under the provisions of the International Registration Plan (IRP), is an optional method of registering commercial vehicles operating interstate. The IRP was developed by the American Association of Motor Vehicles Administrators (AAMVA), to authorize commercial vehicle registration programs which recognize the unique needs of interstate vehicle operations and promote commerce. The IRP licensing agreement provides for apportioned registration fee assessment and licensing on behalf of all participating member jurisdictions. Under this agreement, carriers select a single BASE jurisdiction. The base jurisdiction processes the registration application, collects the fees and issues the operating indicia.
