Fact sheet number one Trailer Identification

My trailer does not have a Vehicle Identification Number or chassis number?

It is a requirement for all vehicles (which include trailers) to have a Vehicle Identification Number (VIN)/Chassis number stamped or welded into a prominent non removable part of the vehicle as a means of identification.

If a second hand trailer is presented to an Approved Inspection Station (AIS) for a pre-registration inspection and does not have a VIN/Chassis number a statutory declaration may be required from the new owner, old owner and/or last registered operator to help establish the identity of the trailer. This may well alleviate the need for the trailer to be presented to Transport Inspectors for an identification check.

Note: If a VIN/Chassis number cannot be verified you will be required to present your trailer to Transport Inspectors for an identification check.

To help us in establishing the identity of the trailer listed below is a check list to assist you when completing a statutory declaration.
