Eligibility Requirements
For full background on what IRP is, see our IRP glossary page. Your vehicle needs IRP registration if it operates in two or more IRP jurisdictions and meets any of these criteria:
Two axles and over 26,000 lbs gross vehicle weight
Three or more axles regardless of weight
Used in combination when the combined weight exceeds 26,000 lbs
Choosing Your Base Jurisdiction
Your base jurisdiction is where you file your IRP application and receive your plates. It must be the state where:
Your vehicles are dispatched, controlled, or operated from
You maintain operational records (or can make them available)
Your vehicles accrue mileage (you must drive at least some miles there)
You Cannot Choose the Cheapest State
Required Documents
Gather these before starting your application:
Vehicle Title or Proof of Ownership
Title, bill of sale, or lease agreement for each vehicle you want to register under IRP.
Proof of Insurance
Current commercial auto liability insurance certificate showing minimum required coverage amounts.
USDOT Number
Your active USDOT number. This links your IRP registration to your federal safety record.
HVUT Payment (Form 2290)
Proof that you have paid the Heavy Vehicle Use Tax for each vehicle. The IRS Schedule 1 stamped receipt is required.
EIN and Business Documents
Your Employer Identification Number and business entity documentation (LLC articles, etc.).
Application Process
Contact Your Base State's IRP Office
Each state handles IRP registration through their motor vehicle department or a dedicated IRP office. Many states now offer online applications. Contact your base state to get the application form and instructions specific to their process.
Complete the Application
Provide your business information, vehicle details (VIN, year, make, model, weight), and mileage data. First-year applicants provide estimated mileage by jurisdiction. Include all jurisdictions where you plan to operate.
Submit Documents and Mileage
Submit all required documents along with your application. Your state's IRP office calculates the apportioned fees based on your mileage distribution across jurisdictions. See our IRP fees guide for how this calculation works.
Pay Fees
After fee calculation, pay the total apportioned amount. Payment options vary by state but typically include check, money order, and credit/debit card. Some states offer payment plans for larger amounts.
Receive Plates and Cab Card
After processing (typically 2-4 weeks), your base state issues apportioned plates and a cab card for each registered vehicle. The cab card must be carried in the vehicle at all times.
Apply for Temporary Permits While Waiting
Fee Calculation
IRP fees are calculated using the apportionment formula: your percentage of miles in each jurisdiction multiplied by that jurisdiction's full registration rate. First-year registrants use estimated mileage; subsequent years use actual reported mileage from the prior period.
For detailed calculation examples and how different routes affect your costs, see our IRP fees calculator guide.
Receiving Your Plates and Cab Card
After your application is approved and fees are paid:
Apportioned plates: Issued by your base state with "Apportioned" or "PRP" markings. Mount on your vehicle as you would standard plates.
Cab card: Registration document listing all jurisdictions where your vehicle is registered. Must be kept in the vehicle at all times. Officers check this at weigh stations and during inspections.
Registration sticker (some states): Some states issue a validation sticker for your plates in addition to the cab card.
Renewal Process
IRP registration expires annually. Your base state sends renewal notices 60-90 days before expiration. The renewal process is similar to the initial application but uses actual mileage data from the preceding year instead of estimates. Report your actual miles driven in each jurisdiction accurately — this data determines your fees for the next year.
Do Not Let Your IRP Expire
Adding and Dropping Vehicles
Your fleet changes during the year? IRP handles that through supplemental applications:
Adding a vehicle: File a supplemental application with your base state. You will owe prorated fees for the remaining months in your registration year. New plates and cab card are issued for the added vehicle.
Dropping a vehicle: Notify your base state to remove the vehicle from your IRP fleet. You may receive a credit that can be applied to other vehicles or future registration fees.
Adding jurisdictions: If you start running new routes through states not on your cab card, file a supplemental application to add those jurisdictions. Additional fees apply based on the mileage apportionment.
Temporary Permits While Waiting
If you need to operate before your IRP is fully processed, temporary options include:
Temporary cab card: Some states issue a temporary cab card while your permanent one is being printed and mailed.
Trip permits: Single-trip or multi-trip permits purchased from individual states. These are a stopgap, not a replacement for IRP registration.
How Our Team Helps with IRP
Route planning that matches your cab card
We dispatch loads based on the jurisdictions listed on your cab card. If a load requires travel through a state not on your registration, we help you understand the supplemental application or trip permit options before accepting.
Renewal tracking
We monitor IRP expiration dates and remind carriers well in advance of renewal deadlines. Since IRP renewal takes weeks to process, early reminders prevent gaps in registration.
New carrier setup guidance
For carriers getting started, we explain where IRP fits alongside your DOT number, MC authority, IFTA, and UCR in the complete compliance picture.
