IRP Apportioned Registration for New Carriers

IRP — the International Registration Plan — is how interstate commercial vehicles get licensed to operate in multiple states with a single set of plates. If you’re operating under an MC number and crossing state lines, you need IRP apportioned registration instead of (or in addition to) standard state vehicle registration.

What IRP Is

IRP is an agreement among the 48 contiguous U.S. states, Washington D.C., and Canadian provinces. Under IRP, a carrier registers its vehicles in one base jurisdiction and pays registration fees apportioned across all jurisdictions where the vehicle operates — based on the percentage of miles driven in each.

Instead of buying a separate license plate from every state you drive through, you pay one registration fee (distributed to the states based on mileage) and receive one set of apportioned plates that are recognized throughout IRP member jurisdictions.

Your Base Jurisdiction

Your base jurisdiction is the state where:

• Your vehicle(s) are based
• Your principal place of business is located
• Your records are maintained

For most owner-operators, this is your home state. IRP registration is handled by your base state’s DMV or motor carrier vehicle registration office — not by FMCSA.

How Fees Are Calculated

IRP fees are apportioned based on the percentage of total miles driven in each jurisdiction during the prior reporting period. For new carriers with no prior mileage history, most states use an “estimated” or “full” registration — meaning you pay as if you operated in all jurisdictions at the full registration rate.

After your first year, your actual mileage by state is used to calculate the apportionment. Carriers who drive primarily in high-fee states pay more; carriers concentrated in low-fee states pay less.

Registration weight matters. The GVWR you register under determines the fee in most states. Register for the maximum weight you actually operate at — you cannot legally operate heavier than your registered weight.

Registering for IRP as a New Carrier

1. Contact your base state’s IRP/DMV office. Search your state name + “IRP registration” or “apportioned registration.” Most states have a dedicated commercial vehicle registration section.

2. Gather required documents. Typically:

   • USDOT number
   • MC number (if applicable)
   • Vehicle information (VIN, year, make, GVWR)
   • Title or proof of ownership
   • Form 2290 stamped Schedule 1 (proof of HVUT payment for vehicles over 55,000 lbs GVWR)
   • Business name, address, EIN

3. Provide mileage estimates (new carrier). As a new carrier, you’ll estimate mileage by state for the apportionment calculation. Be reasonable — the estimate affects your fee.

4. Pay the registration fee. Fees vary significantly by state and weight. Budget for this as a startup cost — IRP registration for a new single truck can range from several hundred to over a thousand dollars depending on your state and operating weight.

5. Receive plates and cab card. Your apportioned plates display your base state and an “APP” designation. The cab card lists jurisdictions and weights — carry it in the vehicle.

What You Must Carry

At all times while operating:

• Apportioned IRP plates (displayed on the vehicle)
• Cab card (carried inside the vehicle)
• IFTA license (if applicable)

Roadside inspections will verify both. A missing or expired cab card can result in an out-of-service order.

Annual Renewal

IRP registration renews annually. Your base state sets the renewal deadline — most renewals align with your registration anniversary month.

At renewal:

• Submit actual mileage by state from the prior year (from your ELD or IFTA mileage records)
• Pay the apportioned fee based on actual mileage
• Receive new registration and updated cab card

The mileage data you’ve been tracking all year for IFTA is also what you need for IRP renewal. Keep the same records.

Startup Considerations

IRP plates and fees are one of the larger startup costs for a new carrier. Budget for:

• Initial registration fee (varies widely by state and weight)
• Form 2290 (HVUT) stamped Schedule 1 — required before IRP registration in most states
• Time — allow 1–2 weeks for processing in most states

Do not operate an unregistered vehicle interstate, even with a newly active USDOT/MC number. The vehicle registration (IRP) and federal operating authority (MC number) are separate requirements that must both be in place.

Frequently Asked Questions

Can I use regular state plates for interstate trucking?

For most interstate commercial vehicles, standard state plates are not sufficient — you need apportioned IRP plates. Some limited operations (primarily intrastate) may qualify for regular registration, but if you have an MC number and operate across state lines, you almost certainly need IRP registration. Confirm with your base state DMV.

How long does it take to get IRP plates?

Processing time varies by state, from a few days to a few weeks. Some states allow temporary operating authorities (trip permits) while your IRP application is processing. Don't plan to operate before your plates arrive without verifying whether a trip permit is needed.

What is a 'cab card' and why do I need it?

The cab card (also called an IRP cab card or apportioned registration card) lists the states and provinces where your vehicle is registered to operate, and the weights for each jurisdiction. You must carry it in the vehicle at all times. It's separate from the license plate — both are required.
