How Do I Get Apportioned Plates (IRP Registration)?

You get apportioned plates by applying for IRP registration through your base jurisdiction's IRP office, which means the state or province where your business is established, your fleet accrues mileage, and your records are kept. You'll gather your USDOT number, MC authority (if for-hire), EIN, title or lease documents, proof of insurance, and a stamped Schedule 1 from Form 2290, then file an application listing every state you plan to run in and pay fees apportioned to your fleet's mileage in each one. Most carriers get plates within a few weeks.

This is the how-to companion to our overview of what apportioned plates actually are. If you still need the basics on IRP, jurisdictions, and why apportioned registration exists, read that first. Here we walk through the actual application process from base jurisdiction to cab card in hand.

Step one: establish and prove your base jurisdiction

IRP is a reciprocity agreement between U.S. states (except Alaska and Hawaii), the District of Columbia, and most Canadian provinces. You don't pick your base jurisdiction out of convenience, it has to satisfy specific legal tests, and your IRP office will ask you to prove it. Under the IRP plan, your base jurisdiction must be the one where:

• You have an established place of business, a physical structure, owned or leased, where business records are kept and that is staffed during normal business hours.
• Mileage is accrued by the fleet in that jurisdiction, meaning the vehicles actually operate there, not just register there on paper.
• Operational records of the fleet are maintained, or can be made available, in that jurisdiction.
• You have a residence or the entity is registered to do business there, for corporations and LLCs.

Carriers sometimes try to base their fleet in a state with lower fees or friendlier audit history even though the trucks never touch the place. IRP offices watch for this, and if you can't produce a lease, utility bill, or staffed office to back up your address, expect the application to get bounced back or flagged for verification. Pick the jurisdiction where you can genuinely document a business presence.

Documents to gather before you apply

Nearly every rejected or delayed IRP application comes down to missing paperwork. Assemble these before you start the online or in-person application so you're not making multiple trips or re-submitting:

• USDOT number, active and in good standing; a deactivated number will stall your application.
• MC number / operating authority, if you're a for-hire carrier hauling regulated freight interstate.
• EIN or, for sole proprietors, a Social Security number, to establish the registrant identity.
• Vehicle title, or if the vehicle is leased, the lease agreement showing you as lessee with authority to register it.
• Proof of liability insurance meeting the minimums for your operation, current and matching the vehicles being registered.
• Stamped Schedule 1 from IRS Form 2290, the Heavy Vehicle Use Tax return, required for any vehicle with a taxable gross weight of 55,000 pounds or more.
• Lease agreements for any owner-operators leased onto your authority, showing equipment details and the term of the lease.
• Proof of an established place of business in your base jurisdiction, a deed, lease, or utility bill in the business name.
• Prior year's mileage records, if you're renewing rather than applying as a first-year fleet.
• Vehicle specifics for each unit: VIN, make, model, year, unladen weight, and the combined gross weight you want registered in each jurisdiction.

The application walkthrough

The exact portal or paper form differs by state, but the sequence of steps is consistent across every IRP jurisdiction.

1. Confirm your base jurisdiction and set up or verify your carrier account with that state's IRP office (often the same office that handles IFTA).
2. Gather the documents above, USDOT number, MC authority if applicable, EIN, title or lease, insurance, stamped Schedule 1, and proof of established place of business.
3. Complete the IRP application (commonly called a Schedule A/B or a similarly named cab card application), listing every vehicle to be registered and every jurisdiction you intend to operate in, even states you'll only pass through occasionally.
4. Report your mileage. Renewing fleets use actual distance traveled in each jurisdiction during the reporting period; first-year fleets with no operating history use the average per-vehicle distance chart your base jurisdiction publishes.
5. Calculate or let the state system calculate your apportioned fees, each jurisdiction's registration fee is prorated by the percentage of your fleet's total miles driven there.
6. Pay the total fee, which is usually due in full at application even though it represents dozens of separate state and provincial fee allocations.
7. Wait for processing. Most jurisdictions issue cab cards and plates within one to four weeks, faster if you apply online and your documents are complete.
8. Receive your cab card and plate, and place a copy of the cab card in each vehicle, the original or a legible copy must be carried at all times.

First-year applicants: the average per-vehicle distance chart

If your fleet has no operating history, a new authority, a new truck added to an existing fleet with no mileage record in a given jurisdiction, or a carrier just starting up, you can't report actual miles because there aren't any yet. Every base jurisdiction publishes an average per-vehicle distance (APD) chart that assigns a standardized mileage estimate for each jurisdiction, and you use those figures instead of real mileage to calculate your apportioned fees for the first registration year.

The APD chart numbers are set by the base jurisdiction and updated periodically. Once you complete a full mileage reporting period with actual operating data, you switch to reporting your real distance traveled for all future renewals, the estimate chart is strictly a first-year workaround, not a permanent option.

The mileage reporting period and renewals

IRP renewals run on an annual cycle set by your base jurisdiction, and most jurisdictions use a mileage reporting period that runs from July 1 through June 30 of the year preceding the registration year. So a registration year beginning January 1, 2026, in a jurisdiction on that standard cycle would use mileage from July 1, 2024 through June 30, 2025 to calculate the fee split.

This means the miles you drove more than a year before your plates take effect determine what you pay, a lag that catches carriers off guard when their operating footprint changes significantly (say, they picked up a big lane into a new state) but the fee allocation hasn't caught up yet. You can't retroactively adjust a completed reporting period; the fix is to add the jurisdiction going forward and let the next renewal cycle reflect the new mileage.

What a cab card is and why it matters

The cab card is the proof of your IRP registration. It lists the vehicle's identifying information, the jurisdictions you're registered to operate in, and the maximum gross weight authorized in each one. Roadside enforcement checks the cab card against the jurisdiction you're driving through and the weight you're carrying, if a state isn't listed on the card, or your weight exceeds what's authorized for that state, you're out of compliance even though the truck has valid plates.

Keep the current cab card in the vehicle at all times, not last year's copy. When you add a jurisdiction or increase a weight mid-year through a supplement, request an updated cab card immediately, driving on an outdated card is a common cause of roadside citations even when the underlying registration is technically fine.

Adding or removing vehicles and jurisdictions mid-year

You don't have to wait for renewal to change your fleet or your footprint. IRP jurisdictions handle mid-year changes through a supplement to your existing registration:

• Adding a vehicle, file a supplement with the new unit's details; fees are prorated for the remainder of the registration year.
• Deleting a vehicle, file a supplement to remove it; some jurisdictions issue a partial credit or refund, others apply it to a future renewal, so ask your specific IRP office.
• Adding a jurisdiction, if you pick up freight into a new state you weren't originally registered for, file a supplement before you run there, not after.
• Increasing gross weight, if you need to carry heavier loads into a jurisdiction than your cab card currently authorizes, a weight supplement is required before you operate at the higher weight.

Supplements typically process faster than a full application since your base account and documents are already on file, often just a few business days.

Timelines and typical fees

There is no single IRP fee schedule, every jurisdiction sets its own base registration fee, and your total bill is the sum of each jurisdiction's fee prorated by your percentage of miles there. A fleet running heavy mileage through a handful of high-fee states will pay more than one spreading light mileage across many low-fee ones, even with identical trucks.

Trip permits and temporary authority while you wait

If you need to move a load into a jurisdiction before your IRP application or supplement is processed, don't just go, get a temporary trip permit from that jurisdiction first. Trip permits are single-trip or short-duration authorizations, typically valid for a matter of days, that let you legally operate in a state you're not yet apportioned for. Most states sell them online or through permit services, and costs generally run in the range of $25 to $150 depending on the state and vehicle weight.

Trip permits are a stopgap, not a substitute for getting properly registered. If you find yourself buying trip permits into the same state repeatedly, that's a sign you should add the jurisdiction to your IRP registration through a supplement instead, it will almost always be cheaper over time and removes the risk of forgetting a permit before a run.

Renewal calendar and common causes of rejection

Base jurisdictions assign renewal dates on a staggered calendar, so your renewal month is fixed once you're first registered, it doesn't automatically move to January or match the calendar year. Mark your renewal date and start gathering mileage records and updated documents 60 to 90 days ahead so you're not filing at the last minute.

• Lapsed or mismatched insurance, the policy on file has to be active and match the vehicles and liability limits required.
• Expired or missing Schedule 1 for Form 2290 on any vehicle 55,000 pounds or over.
• USDOT number deactivated or MCS-150 update overdue, which can freeze IRP processing entirely.
• Incomplete jurisdiction list, leaving out a state you actually run in, discovered later during an audit or roadside stop.
• Mileage figures that don't reconcile with your IFTA filings for the same period, auditors and clerks cross-check the two.
• Unpaid fees or fines from a prior registration year still outstanding with the base jurisdiction.

Record retention and the IRP audit obligation

IRP registrants are subject to audit by their base jurisdiction, and the record-keeping requirement is not optional. You're expected to keep individual vehicle distance records, trip reports or equivalent electronic records showing the date, origin and destination, route, and miles traveled per jurisdiction for every trip, for the current registration year plus the three prior years.

Records that typically get pulled in an IRP audit include:

• Individual vehicle mileage records (trip sheets, GPS/ELD-derived summaries, or equivalent) broken out by jurisdiction.
• Fuel receipts and bulk fuel withdrawal records supporting your IFTA filings for the same period.
• Lease agreements for any leased vehicles or leased-on owner-operators included in the fleet.
• Maintenance and titling records confirming vehicle ownership or lease status.
• Prior IRP applications, supplements, and renewal filings for the audited years.

An IRP audit that turns up under-reported mileage in high-fee jurisdictions can result in an assessment for back fees plus interest and penalties across your whole fleet, not just the vehicle in question, so sloppy mileage tracking on a handful of trucks can turn into a fleet-wide bill. Keep contemporaneous, vehicle-by-vehicle records rather than trying to reconstruct them from memory at audit time.

Where Long Haul Compliance fits in

IRP registration touches base jurisdiction rules, mileage reporting, mid-year supplements, and audit-ready recordkeeping all at once, and getting any one piece wrong can delay your plates or trigger a fee assessment later. Long Haul Compliance handles IRP filings, trip permits, and tag renewals for carriers who would rather run their trucks than chase paperwork through a state IRP portal, we file the application, track your renewal calendar, and keep your cab cards current across every jurisdiction you operate in.
