If your trucks are based in New Jersey and cross into other states, the plates on them are probably apportioned plates issued under the International Registration Plan (IRP). One plate and one cab card cover every IRP jurisdiction you run in, and New Jersey collects the registration fees for all of them and shares the money out by your miles.
The plan is shared by every member state, but the paperwork is not. New Jersey has its own rules on what counts as a place of business, what proof of address it accepts, and where you can file. This guide walks through them, using the New Jersey Motor Vehicle Commission (NJ MVC) IRP Carrier Guide, its IRP FAQ and the current IRP application packet. Rules change, so check those pages before you file.
Which trucks need apportioned plates
The NJ MVC IRP page says the plan covers vehicles used or intended for use in two or more member jurisdictions that carry property and are one of these:
- “A power unit with two axles and a registered vehicle weight (or gross vehicle weight) in excess of 26,000 pounds”
- “A power unit with three or more axles, regardless of weight”
- “A vehicle combination, when the gross weight of such combination exceeds 26,000 pounds”
The exceptions listed on that page are “Recreational vehicles, vehicles displaying restricted plates, or government-owned vehicles.” The FAQ adds trailers, school buses and vehicles running under separate reciprocity agreements. A truck that never leaves New Jersey is not an IRP vehicle. For how the fees are worked out, see how IRP plate costs are calculated.
Can New Jersey be your base jurisdiction?
You register in your base jurisdiction, and New Jersey only takes you as a New Jersey account if the business really operates there. Section 5.0 of the Carrier Guide asks for an established place of business in New Jersey that you own, lease or rent, miles run in New Jersey, and fleet records “maintained or made available in New Jersey.” It also rules out two shortcuts: you cannot use an agent’s or consultant’s address as your place of business, and you cannot “use a P.O. Box or virtual address as the business address.”
The current IRP definition, printed in the application packet, goes further. The building has to be owned, or leased for at least 12 months, and “shall have clear company signage and hours of operation posted, be open for business and shall be staffed a minimum of 20 hours per week by one or more persons employed by the Applicant or Registrant on a permanent basis (i.e., not an independent contractor).” It also says “virtual and/or shared office spaces shall not qualify.” A carrier with no established place of business anywhere can still base in the state where it can show residence, along with miles and records there.
Proof of address New Jersey accepts
A September 2025 notice in the packet “supersedes any prior instructions concerning proofs of address.” You need this proof when you open an account, renew a registration or change an address. What you send depends on the kind of property and the tax number you register under:
| Your situation | Documents required |
|---|---|
| Business on commercial property | SS-4 form or Certificate of Authority, plus a notarized business property lease or a utility bill (water, sewage, electric, gas), plus a photo of the company signage and posted hours |
| Business on residential property, registering with a FEIN | SS-4 form or Certificate of Authority, plus a notarized property lease or a utility bill; the bill may be in a personal name if the name and address match the SS-4 |
| Residential property, registering with an SSN | A valid New Jersey driver license and a notarized lease or utility bill, plus one secondary document such as a tax return filed from that address, the New Jersey title of the vehicle, a property tax bill, or first class mail from a government agency other than MVC dated in the last six months |
A few details trip people up. If the FEIN on a Certificate of Authority is followed by 500, MVC treats it as a temporary number and will not accept it. Leases must be notarized, run at least 12 months and cover the registration period. Names and addresses have to match across every document, and MVC can ask for more.
Title, insurance and federal numbers
Several things have to be in place before New Jersey will process the application:
- A New Jersey title. The Carrier Guide says “IRP applications can only be processed with a New Jersey title on record,” even if the truck is titled in another state today.
- An MVC Entity Identification Number. A business registering vehicles in New Jersey gets “a 15-digit EIN that will be required for all transactions.” It used to be called the corporation code. Our guide to the New Jersey EIN covers how to get one.
- Insurance. MVC says a certificate of insurance is required for any apportioned vehicle on the road and “must show the $1.5 million coverage under Automobile Liability Insurance.”
- USDOT number and Taxpayer ID. Both are mandatory, the USDOT number must be registered as interstate, and the TIN must be the one used for your MCS-150 updates.
- Form 2290. Trucks registered at 55,000 pounds or more need proof the heavy vehicle use tax is paid. Check every VIN: per the Carrier Guide, “if your VIN is wrong by even one character, we are required by Federal Law to reject the registration.” See why Schedule 1 matters for plates.
IRP registration

Register nowHow to file in New Jersey
A first application is the Equipment Registration Form (MCS-IRP-1) together with the IRP Registration Certification (IRP-7). The MCS-IRP-1 asks for the business and mailing addresses (no PO box for the business address), contact details, weights, equipment numbers, vehicle descriptions, purchase prices, lease and insurance information, and your USDOT and TIN numbers.
The FAQ is clear that a regular motor vehicle agency cannot help: “Apportioned registrations may only be obtained at Motor Carrier Services, 120 South Stockton Street, Trenton, NJ 08666.” Some transactions can also be done through the mCarrier online portal, by mail to the IRP Section at 225 East State Street, P.O. Box 133, Trenton, NJ 08666-0133, or by email to mcscustomerservice@mvc.nj.gov. Two practical notes from MVC:
- Since October 7, 2024 every customer needs a new mCarrier user. New accounts are approved by hand, so do not submit the request more than once.
- If an emailed application is missing documents, you have to resend all documents along with the ones requested, not just the missing piece.
Timing per the Carrier Guide: “approximately 2 to 3 weeks to complete an application transaction by mail.” In person, a complete application “will normally be done that day.” If someone files for you, a “blanket Power of Attorney is required for all transactions processed for that account.”
What you pay and how it is split
New Jersey bills you once for every jurisdiction on your mileage schedule. Each state’s share depends on your miles there as a percentage of total IRP miles, plus its own fee schedule for the weight and vehicle. The New Jersey part is based on gross weight, then reduced by your New Jersey miles divided by total IRP miles in the reporting year, which runs July 1 through June 30 of the previous year.
The Carrier Guide’s sample fleet runs 60% of its miles in New Jersey, 39% in Pennsylvania and 1% in Delaware, for a total of $1,404.73. MVC labels those figures “examples only,” so do not use them to budget. The billing notice lists every jurisdiction’s fee; pay the total on page 1. MVC takes cash, check, money order and credit card in person and eChecking through the portal, but not starter checks.
Renewals, added trucks and cancelling
New Jersey staggers registrations: each one expires on the last day of the month, one year after it was issued. The Carrier Guide is blunt: “There is no registration grace period.” Renewal schedules arrive six to eight weeks before expiration, and you cannot change a truck’s weight on the renewal itself.
You can add trucks to a fleet during the year with a supplemental application, and the fees are prorated. To close an account, delete every truck and send an IRP application asking to cancel. The FAQ warns that “Surrendering your plates does not remove the vehicles from your account.”
Waiting on plates: temporary authority and trip permits
New Jersey accounts in good standing can get a temporary apportioned authorization when a renewal or replacement plate is processed online. It is valid for 15 days, counted from the new expiration date for a renewal and from the date of issue for replacement plates. Out of state trucks without apportioned plates can buy a New Jersey trip permit, which “is valid for 72 hours beginning at the time of issue” and costs $25, and there is a separate 96 hour IFTA permit, also $25. More on both in our guide to trip and fuel permits.
Mileage records and audits
Your apportioned fees are only as good as your mileage records, and MVC can audit them. The basic record is an Individual Vehicle Mileage Record for each trip, showing dates, origin and destination, routes or odometer readings, distance by jurisdiction, total distance, unit and fleet numbers, and the driver. Total distance means every mile, “including loaded, empty, deadhead, and bobtail distance.”
The Carrier Guide requires these records to “be kept for five years after the close of the registration year.” The FAQ gives the same five years.
What IRP plates do not cover
Apportioned plates are a registration, nothing more. MVC lists what IRP does not take care of: operating authority in the states you run in, IFTA fuel tax, other taxes such as income and sales tax, length, width, height and axle limits, Form 2290, proof of liability coverage, and the Corporation Business Tax. On fuel tax the FAQ says IRP plates mean you need an IFTA decal, “but it does not have to match the state indicated on your plates.”
