What you need to register a trailer in New Jersey
To register a trailer in New Jersey, you'll submit documents to the Motor Vehicle Commission (MVC) in person or by mail, pay a registration fee, and receive a certificate of registration and license plate. The process differs slightly depending on whether your trailer is new, used, or being transferred from another state. Most people complete registration in one visit to an MVC office, though mail-in options exist if you meet certain conditions.
New Jersey requires all trailers — including utility trailers, boat trailers, and enclosed cargo trailers — to be registered before you operate them on public roads. The state does not issue separate titles for trailers, so you won't need a title document the way you would for a car.
Key Takeaways
- You need proof of ownership (bill of sale or previous registration), proof of New Jersey residency, and a completed MVC-3 form to register any trailer.
- Registration fees vary by trailer weight and type, ranging from roughly $20 to $60 annually, though exact amounts depend on your specific trailer.
- The Motor Vehicle Commission processes most registrations the same day you visit an office, and you'll leave with a temporary registration valid for 30 days while your permanent plate arrives by mail.
- If your trailer is from out of state, you may need an inspection or additional documentation proving the trailer's history and condition.
Documents you'll need to bring
Start by gathering proof of ownership. If you bought the trailer new, bring the bill of sale from the dealer. If you bought it used, bring the bill of sale from the private seller or dealer. If you're transferring registration from another state, bring your previous registration or title from that state.
Next, bring proof that you live in New Jersey. An acceptable document is a driver's license, state ID card, utility bill, lease agreement, or mortgage statement with your current address. The document must show your name and address clearly.
You'll also need to complete form MVC-3, the process for Registration. You can read this form from the MVC website or pick one up at any MVC office. Fill it out before you arrive — this saves time and reduces errors. You'll need your Vehicle Identification Number (VIN), which is stamped on the trailer frame, usually near the tongue or on the left side.
Bring your Social Security number or Individual Taxpayer Identification Number (ITIN). If you're registering the trailer in a business name rather than your own name, bring your business registration documents and the name and address of the business owner.
Registration fees and what they cover
New Jersey charges registration fees based on your trailer's gross vehicle weight rating (GVWR) — the maximum weight the trailer can safely carry, including cargo. The fee structure changes periodically, so the exact amount you'll pay depends on when you register and your trailer's weight class.
Generally, lighter trailers (under 2,000 pounds GVWR) cost less to register than heavier ones. The MVC website lists current fees by weight category, or you can call your local MVC office to confirm the fee for your specific trailer before you visit. The registration is valid for one year from the date you receive it, and you'll need to renew it annually.
The fee covers your registration certificate and one license plate. If you need a replacement plate later, there is an additional charge. Some trailers, such as those used exclusively for agricultural purposes, may may have access to for different fee structures — ask the MVC if your trailer falls into a special category.
How to register in person at an MVC office
Visit any Motor Vehicle Commission office during business hours. Most offices are open Monday through Friday, with some offering Saturday hours. Bring all documents listed above, your completed MVC-3 form, and payment for the registration fee. You can pay by cash, check, or card, depending on the office.
When you arrive, take a ticket from the kiosk or ask staff which line to join. Tell the representative you're registering a trailer. They'll review your documents, confirm your VIN matches your trailer, and process your registration. This usually takes 15 to 30 minutes, depending on how busy the office is.
Before you leave, you'll receive a temporary registration document valid for 30 days. This allows you to legally operate the trailer while your permanent license plate is being made and mailed to you. Your permanent plate typically arrives within two to three weeks. Do not operate the trailer on public roads without either the temporary registration or the permanent plate once it arrives.
Registering by mail or online
New Jersey does not currently offer full online registration for trailers, but you can register by mail if you prefer not to visit an office in person. Mail your completed MVC-3 form, proof of ownership, proof of residency, and a check or money order for the registration fee to the address listed on the MVC website.
Processing by mail takes longer than in-person registration — typically two to four weeks. You won't receive a temporary registration, so you cannot legally operate the trailer until your permanent plate arrives. For this reason, most people find it faster and more practical to register in person at an MVC office.
Some MVC services are available through third-party vendors licensed by the state, such as certain AAA offices or private registration services. These vendors can handle trailer registration for a convenience fee on top of the state registration cost. Call ahead to confirm the vendor near you offers trailer registration.
Registering a trailer from out of state
If you're moving to New Jersey with a trailer registered in another state, you must register it with the New Jersey MVC within a set timeframe — typically 60 days of establishing residency. Bring your out-of-state registration or title, proof of New Jersey residency, and your completed MVC-3 form.
The MVC may require an inspection to verify the trailer's condition and confirm the VIN matches your documentation. Some out-of-state trailers need an inspection at a licensed inspection station before registration can be completed. The MVC will tell you whether your trailer needs an inspection when you submit your documents. Inspections cost between $15 and $25 and take about 15 minutes.
If your out-of-state registration has expired, you can still register in New Jersey using your previous registration as proof of ownership. If you have neither a current registration nor a title, bring a bill of sale or other documentation showing you own the trailer.
Renewing your trailer registration
Your registration expires one year from the date it was issued. The MVC will mail you a renewal notice about 30 days before expiration. You can renew by mail, online through the MVC website, or in person at an MVC office. Renewing by mail or online is faster than the initial registration because you don't need to provide proof of ownership again — only proof of residency if your address has changed.
If you renew online, you'll pay the fee by card and receive a temporary registration when ready. Your new plate will arrive by mail within two to three weeks. If you miss the renewal important date, you can still renew, but you may face a late fee. Do not operate an unregistered trailer on public roads.
Frequently Asked Questions
Do I need a title for my trailer in New Jersey?
No. New Jersey does not issue titles for trailers. Proof of ownership is your bill of sale, previous registration, or out-of-state title. Once registered in New Jersey, your registration certificate serves as your proof of ownership.
What if my trailer doesn't have a VIN?
Most trailers manufactured after the 1980s have a VIN, but older or homemade trailers may not. Contact your local MVC office to ask about registering a trailer without a VIN. You may need additional documentation or an inspection to establish ownership and the trailer's specifications.
Can I register a trailer if I don't have a New Jersey driver's license?
Yes. You need proof of New Jersey residency, not a driver's license. A utility bill, lease, or mortgage statement with your name and address works. If you're not a U.S. citizen, bring your ITIN instead of a Social Security number.
What happens if I operate a trailer without registration?
Operating an unregistered trailer on public roads is illegal in New Jersey and can result in a traffic citation and fine. If you're stopped, you must show your registration or temporary registration document. Register your trailer before you use it on any public road.
How do I replace a lost or damaged license plate?
Visit an MVC office with your registration certificate and proof of residency. Pay the replacement fee, which is typically $10 to $15. You'll receive a new plate the same day or within a few days by mail, depending on the office's procedures.
