What you need to do to register a trailer
Trailer registration is a state-level process, not federal, so the exact steps depend on where you live. Most states require you to visit your Department of Motor Vehicles (DMV) or equivalent agency in person, bring proof of ownership and your vehicle identification number (VIN), and pay a registration fee. Some states let you renew by mail or online after the first registration, but initial registration almost always requires a physical visit.
The process typically takes 15 to 30 minutes at the DMV, though wait times vary. You will leave with a registration certificate and a registration sticker or plate to display on the trailer. Many states require this sticker to be visible before you can legally tow the trailer on public roads.
Key Takeaways
- You must register your trailer in the state where you primarily keep it, not where you bought it or where you live if those differ.
- Bring the bill of sale or title document, your VIN, proof of your identity, and proof of your address to the DMV.
- Registration fees vary by state and sometimes by trailer weight or type, ranging from under $50 to several hundred dollars annually.
- Most states require registration before you tow the trailer on public roads, even if you are only moving it a short distance.
- Renewal timing and methods (mail, online, in-person) depend on your state; check your state DMV website for the specific schedule.
Gather your documents before you go to the DMV
The DMV will ask for proof that you own the trailer. If you bought it new, bring the bill of sale from the dealer. If you bought it used, bring the title document (sometimes called a certificate of title) signed over to you by the previous owner. Some states accept a bill of sale alone for used trailers under a certain value; check your state DMV website to confirm what they accept.
You will also need the trailer's VIN, which is stamped on the frame or printed on the title. Bring your driver's license or state ID and a document showing your current address — a utility bill, lease, or mortgage statement usually works. If someone else is registering the trailer on your behalf, bring a signed power of attorney form; your state DMV website will have the correct form to use.
Some states require a bill of sale even if you have a title, and some require proof of a safety inspection or emissions test. Before you go, visit your state's DMV website and search for "trailer registration requirements" to see the full list for your state.
Understand registration fees and what affects them
Registration fees are set by your state and do not vary by where you register within that state. However, the fee often depends on the trailer's gross vehicle weight rating (GVWR) — the maximum weight it can safely carry, including cargo. A small utility trailer might cost $30 to $60 per year, while a large enclosed or horse trailer could cost $150 to $300 or more.
Some states charge different fees for different trailer types: utility trailers, boat trailers, livestock trailers, and commercial trailers may each have their own rate. A few states also charge a one-time title fee in addition to the annual registration fee. Your state DMV website will list the exact fee for your trailer type and weight class.
Registration is usually valid for one to three years depending on your state. When it expires, you will need to renew it; many states send a renewal notice by mail a few weeks before expiration.
Complete registration at the DMV or online if your state allows it
For your first registration, most states require you to visit a DMV office in person. Bring all your documents, your VIN, and the registration fee. The clerk will verify your documents, record the VIN, and issue your registration certificate and sticker. Some DMVs are busier than others; calling ahead or checking online wait times can help you pick a less crowded time.
After your initial registration, many states allow you to renew by mail or online. You will receive a renewal notice in the mail with instructions. Some states send a renewal form you fill out and mail back with a check; others let you renew through their website using a credit card. Check your state DMV website to see whether renewal by mail or online is available in your state.
A few states require in-person renewal every few years, usually to verify that the trailer still exists and matches the registration records. If your state requires this, you will receive notice in the mail telling you when to come in.
Display your registration sticker or plate correctly
Once you receive your registration, your state will issue either a sticker or a metal plate to display on the trailer. Most states use a sticker that you affix to the back of the trailer frame or to the tongue. A few states issue a small metal plate similar to a license plate. Check your registration certificate or the DMV website to see what your state uses and where to place it.
The sticker or plate must be visible and legible from a distance; if it is obscured by dirt, damage, or cargo, you can be cited. Replace a damaged sticker or plate by visiting the DMV or requesting a replacement through your state's online system if available. Replacement usually costs $5 to $15.
Know the rules if you move to a different state
If you move to a new state and plan to keep the trailer there, you must re-register it in your new state within a set time frame — usually 30 to 90 days. You will need to surrender your old registration and obtain a new one from your new state's DMV. Some states require a new title as well; others will transfer your existing title to the new state.
If you are moving temporarily and plan to return to your original state, you may not need to re-register when ready. However, if you are stopped by law enforcement, you must be able to show that you are a resident of your original state. Check your new state's DMV website for the specific rules on how long you can keep out-of-state registration.
Understand what happens if you do not register
Towing an unregistered trailer on public roads is illegal in all states. If you are stopped, you can receive a citation and fine, which varies by state but typically ranges from $50 to $500 or more. Some states also allow law enforcement to impound the trailer until it is registered.
Even if you are only moving the trailer a short distance — from a dealer to your home, or from one property to another — you need registration first. Some states allow a temporary permit or transit pass for a single trip, but you must obtain this before you tow. Check your state DMV website to see whether a temporary permit is available and how to get one.
Frequently Asked Questions
Do I need to register a trailer if I only use it on private property?
No. If the trailer never leaves private property that you own or have permission to use, registration is not required. However, the moment you tow it on a public road — even to cross a street or move it to a different property — you must have current registration.
What is the difference between a title and registration?
A title is a document that proves you own the trailer. Registration is a permit that allows you to tow it on public roads. You need both: the title stays with you as proof of ownership, and the registration sticker or plate must be displayed on the trailer while you are using it.
Can I register a trailer without a title?
It depends on your state and the trailer's age. Some states allow registration with a bill of sale alone for older trailers or trailers under a certain value. Others require a title no matter what. If you bought a used trailer and the seller did not provide a title, contact your state DMV to ask what documents they will accept, or ask the seller to obtain a duplicate title from their state.
How long does it take to get a registration sticker after I register?
If you register in person at the DMV, you usually receive your sticker the same day. If you renew by mail, the sticker arrives within one to two weeks. If you renew online, some states mail the sticker when ready; others may take a few weeks. Check your state DMV website for the specific timeline.
What if my trailer's registration expires while I am using it?
You cannot legally tow it on public roads once it expires. If you are caught, you can be cited. Renew before the expiration date shown on your registration certificate. Most states send a renewal notice 30 to 60 days before expiration, so watch your mail or check your online DMV account.
