trailer registration

Trailer registration by state

Most states require any trailer towed on public roads to carry a title or registration, but the agency, the paperwork, and whether the rule depends on trailer weight vary by state. Pick your state below for the sourced, step-by-step process.

This guide covers general-purpose, cargo, and travel trailers towed behind a car or truck. Utility trailers and RVs/motorhomes have their own dedicated guides, since several states treat them under different rules.

What to know before you go

General guidance, not legal advice.

Proof of ownership comes first

Nearly every state asks for a title, a manufacturer’s certificate of origin, or a bill of sale before it will issue a registration or plate. A homemade or older trailer without a title usually needs a separate title-application process before registration.

Weight can change the rule

A number of states only require registration above a set gross weight, or price the fee by weight class. Check your state’s page below for whether a weight threshold applies before you assume a small utility trailer is exempt.

The plate or permit is usually issued locally

Most states issue the trailer plate through a county tag office, license plate agent, or DMV field office rather than by mail from the state capital. Confirm the exact office in the state guide below before you drive over.

What to bring

Documents most states ask for.

Title, manufacturer’s certificate of origin, or bill of sale (proof of ownership)
Government-issued photo ID
Proof of the trailer’s weight, if your state prices by weight class

This is a general list — the exact documents for your state are listed on that state’s page above, sourced from the agency.

Common questions

The practical details.

Do I have to register a small utility trailer?

It depends on the state and, in several states, on the trailer’s weight. Some states exempt trailers under a set gross weight from registration entirely, while others require every trailer towed on public roads to carry a plate. Check your state’s guide below — never assume a small trailer is exempt without confirming with the agency listed there.

What if my trailer never came with a title?

Homemade trailers and some older trailers were never titled. Most states have a bonded-title or title-application process for exactly this situation — it usually starts at the same agency that handles trailer registration. The state guide below names that agency.

Does a trailer registration expire?

Renewal cadence varies by state — some trailers renew annually, others are registered for multiple years or permanently for a one-time fee. The renewal cadence for your state is listed on its guide page below.
