Step-by-Step
How to Register a Trailer in Oklahoma
All trailers towed on public roads in Oklahoma must be registered with Oklahoma Tax Commission. Here is the standard registration process:
1
Gather Required Documents
You will need proof of ownership (Manufacturer's Certificate of Origin for new trailers, or the current title for used trailers), a valid photo ID, and payment. If the trailer was previously registered in another state, bring those documents as well.
2
Determine Your Trailer's GVWR
Oklahoma uses a weight-based fee schedule - you'll need to know your trailer's Gross Vehicle Weight Rating (GVWR). This is usually listed on a tag on the trailer frame or tongue.
