The International Registration Plan (IRP) is an agreement among U.S. states, the District of Columbia, and Canadian provinces that simplifies vehicle registration for carriers operating across multiple jurisdictions. Instead of registering in every state or province, you register once with the DMV or IRP office in your base jurisdiction. You then receive IRP credentials, which include: An apportioned license plate A cab card, issued under the oversight of IRP, Inc. The cab card must be carried in the truck at all times. Many carriers also keep scanned or digital copies for roadside inspections.
You must register for IRP if your vehicle:
You do not need IRP credentials if your vehicle is:
Owner-operators working under their own DOT authority must also file for IRP credentials if their equipment meets any of the above requirements.
You must have IRP credentials ready before you begin operating interstate or across provinces. Renewals are required annually, though the renewal month varies by state.
You also need to update your IRP record within 30 days if:
Each state sets its own renewal schedule, so check your base jurisdiction’s requirements and mark your deadlines well in advance. Keeping accurate mileage records throughout the year makes renewals and updates faster, smoother, and audit-ready.
There are multiple ways to get your IRPS credentials. You can file for IRP credentials online, in person, or through an agent/service bureau. The process is similar across states, but forms and deadlines differ.
Useful for large fleets or carriers operating in multiple jurisdictions.
Most states will require the following to issue IRP credentials:
Some states may ask for additional items, such as tax IDs or safety records.
Your IRP Registration cost depends on multiple factors, including your vehicle’s weight, the number of jurisdictions you operate in, and how your miles are distributed across them. Common fees include:
Fees are apportioned using this formula:
(Miles in jurisdiction ÷ Total miles) × That jurisdiction’s registration fee rate.
Example: Suppose your truck’s total registration fee comes to $1,800 for the year. If you drove 40,000 miles in one jurisdiction and 20,000 miles in another, about $1,200 of the fee would go to the first jurisdiction and $600 to the second.
For most carriers, the total annual cost for IRP credentials typically ranges from $1,500 to $3,000 per truck, though this varies by base state, equipment, and mileage. Keeping accurate mileage logs ensures your fees are calculated fairly and helps prevent costly audits.
Not maintaining valid IRP registration can lead to serious and expensive problems, including:
IRP credentials must be renewed every year to keep your apportioned plates and cab card valid. It’s important to prepare early by gathering mileage records and other required documents well before your renewal date.
To renew:
You must also update your IRP record within 30 days if your fleet changes (such as adding or selling a vehicle) or if your business details change. Mark renewal deadlines in advance to avoid late penalties or downtime.
No. IRP credentials are only required if you operate across multiple IRP jurisdictions. If your trucking operation is intrastate only, you are exempt from IRP registration and can use standard state plates.
IRP registration fees are based on two main factors: your vehicle’s registered weight and the percentage of miles you drive in each jurisdiction. This ensures fees are fairly distributed, so you only pay for the states and provinces where your trucks actually operate.
Yes, apportioned plates can usually be transferred to another vehicle in your fleet, but you must notify your state IRP office and request an updated cab card. Skipping this update could lead to penalties or problems during roadside inspections.
You must complete IRP renewal annually. Renewal deadlines vary by state, so check your base jurisdiction’s schedule and mark it in advance. Late renewals often mean added fees and the risk of being placed out of service.
No. IRP handles apportioned registration and plates, while IFTA (International Fuel Tax Agreement) covers reporting and paying fuel taxes. Most interstate carriers need both IRP and IFTA to stay fully compliant.
To apply for IRP registration, you typically need your vehicle title or lease, proof of commercial insurance, USDOT/MC number, prior mileage records, and proof of residency or business presence. Some states may ask for additional items such as tax ID numbers or safety records.
Operating without valid IRP credentials can lead to fines ranging from $500 to $2,000, vehicle impoundment, and costly audits for misreported mileage. Inspectors may also issue an out-of-service order until you show proof of current IRP registration.
