Title vs. Registration: What's the Difference?
Last reviewed: January 2025
Most people use "title" and "registration" interchangeably when talking about vehicle paperwork — but they're two completely different documents that serve entirely different purposes. Confusing them is one of the most common reasons people arrive at the DMV unprepared.
What Is a Title?
A title (also called a Certificate of Title) is the legal document that proves ownership of the trailer. It functions like a deed to a house. The title lists the owner's name, the trailer's VIN, make, year, and weight. When you sell a trailer, you transfer the title to the buyer by signing the back of it. The title follows the trailer through its entire life — it's issued once per owner and updated each time the trailer is sold.
A title is typically a paper document issued by the state and mailed to the owner. Many states now also maintain electronic records alongside the paper title.
What Is Registration?
Registration is the annual (or multi-year) permission to operate the trailer on public roads. It's the paperwork — and the license plate — that proves you have paid the road fees required by your state and that the trailer is legally authorized to be on the road. Registration expires periodically (usually annually) and must be renewed.
The registration certificate lists the owner's name, trailer description, plate number, and expiration date. The license plate is the physical indicator of valid registration when you're on the road.
Side-by-Side Comparison
| Feature | Title | Registration |
|---|---|---|
| Purpose | Proves ownership | Authorizes road use |
| Issued by | State title office | State / county office |
| How often | Once per owner change | Annually (or biennial) |
| Physical form | Certificate (paper document) | Sticker + registration card |
| Needed to sell | Yes — must be transferred | No |
| Required for road use | Depends on state/weight | Yes — always required |
| Expires | No (unless transferred) | Yes — annually |
Do You Always Need Both?
Not always. Many states have weight thresholds below which a trailer doesn't need a title — only registration. For example:
- Ohio: Trailers 4,000 lbs GVWR or under — registration only, no title required
- Georgia: Trailers under 2,000 lbs GVWR — registration only
- Michigan: Trailers under 2,500 lbs GVWR — registration only
- Montana & South Dakota: Most utility trailers — registration only, titles optional
For trailers above the threshold, you need both. Check our weight exemptions guide or use the Requirement Finder tool for your state.
Why This Matters When Buying
When you buy a trailer, you need to transfer both documents — but in different ways. The title is transferred by the seller signing the back of the physical title document. The registration is not transferred — you get new registration in your own name by visiting the title office and registering it yourself.
Never accept a trailer sale where the seller claims the registration is "transferable." The registration belongs to the registered owner — it doesn't transfer with the sale. You'll need to get your own registration after completing the title transfer.
Can I register a trailer without a title?
Yes — in states that don't require a title for your trailer's weight class, you can register using a bill of sale or affidavit of ownership. In states that do require a title, you need the title first before you can register.
What if I have a title but no registration?
You own the trailer legally (the title proves that) but you can't legally tow it on public roads without current registration. You can drive it to the title office to register it, but you technically shouldn't tow it on public roads before getting registration — depending on your state's rules about recently purchased vehicles.
