Apportioned Registration (IRP)

Apportioned registration, also known as the International Registration Plan (IRP), is a program for licensing commercial vehicles engaged in interstate trucking. Apportioned registration lets you obtain registration credentials in one jurisdiction, giving you the freedom of interstate travel without having to purchase trip permits.

If your commercial vehicle is engaged in interstate operation, you may qualify for apportioned registration. To learn if you qualify, please contact one of our Vehicle Titles and Registration (VTR) regional offices or send us an e-mail.

Registration Process

If you qualify for apportioned registration, you can obtain your credentials by:

• Completing and submitting the appropriate registration forms
• Using our new online registration system, called TxIRP

TxIRP allows you to process your apportioned registration application online instead of mailing in your application or waiting in line at the regional office. For more information, read our TxIRP brochure or Renewal Instruction Booklet.

NOTE: Trailers pulled by apportioned power units require token trailer license plates that can be obtained from your county tax office.

Five-Year Token Trailer Registration

Trucks or truck-tractors greater than one ton, with apportioned and combination registration and with a semi-trailer gross weight of 6,000 pounds or more, may apply for five-year token trailer license plates. Legislation passed in 2007 eliminated the 50-trailer minimum eligibility requirement to register trailers for five consecutive years. All owners of token trailers now have the option to register/renew trailers for one year, five years or a portion of the years remaining in the five-year period.

For example, the current five-year period for five-year token trailers expires March 2010. If an owner of a token trailer applies for token trailer registration in September 2007, one of the following types of token trailer registration may be purchased:

• One-year registration through the county tax assessor-collector's office (no change in procedure)
• Three years of registration through the VTR regional office. The owner will pay three years of registration fees and applicable local fees, and is issued a five-year token trailer plate with March 2010 expiration
• Beginning April 2010, five years of registration may be purchased with an expiration of March 2015
