    Welcome to Michigan IRP Online

    International Registration Plate


    The International Registration Plan (IRP) is a program for licensing commercial vehicles (trucks and non-chartered buses) in interstate operations among member jurisdictions. All of North America is included in the IRP, except for Alaska, Hawaii, Mexico and the Canadian Northwest Territories and Nunavut.

    Michigan IRP Online is an electronic credentialing application that allows various types of IRP transactions to be performed via the Internet. You can process renewals, add jurisdictions, add vehicles, increase weights, transfer plates, and request credential replacements. Your vehicles can be on the road in less time with less effort.

    Michigan IRP allows electronic check (e-check) payments. You may print your own temporary authority (TA) permits, valid for 30 days, for all types of transactions except renewals. Temporary authority permits can be printed for renewal transactions only after the renewal has been paid. The IRP office must receive payment before the TA expires.

    Payments can be made either by e-check through IRP Online, by mail, or in person at the Lansing IRP office. Credit cards are not accepted. After payment is received, the IRP office will mail your credentials (cab cards and plates, if needed) to your Michigan business address.
