Low volume trailer VIN terms and conditions


From 1 July 2021 the Road Vehicle Standards Act 2018 replaced the Motor Vehicle Standards Act 1989. The requirements to build light trailers (less than 4.5 tonnes aggregate trailer mass, ATM) changed. If you are a trailer manufacturer, please see Changes that will affect trailer manufacturers.

If you have are a manufacturer or importer of trailers, further information can be found on the DITRDC website (External link).

Use of trailer VINs issued by VicRoads

New low volume trailer VINs are intended for individuals and manufacturers in the business of constructing new trailers. Severe penalties apply under the Road Safety Act 1986 and the Road Safety (Vehicles) Interim Regulations 2020 if a person alters, defaces, removes, substitutes or tampers with an existing vehicle identification number.

If a trailer is entered on an interstate WOVR as a statutory write-off the entire chassis cannot be used to build a trailer or for any trailer repairs. 

If VicRoads identifies any of these activities, the relevant VINs issued by VicRoads will be cancelled and the trailers will not be eligible for registration in Victoria. Any evidence indicating interference with an existing VIN will be referred to Victoria Police.

VicRoads may conduct field audits of a trailer manufacturing company applying for VINs. These audits will be conducted to ensure that VIN allocation and record keeping procedures are maintained. 

Imported trailers

A trailer VIN issued by VicRoads must not be assigned to a trailer manufactured overseas or listed on a Vehicle Import Approval.

VicRoads is notified by the National Exchange of Vehicle and Driver Information System (NEVDIS) if a VicRoads issued VIN is listed on a Vehicle Import Approval. If this occurs, you will not be able to register the trailer/s.

Non-standard trailers

A light trailer VIN must not be assigned to a trailer that does not meet the requirements of VSB1 (External link), is non-compliant or over dimensional.

By affixing a vehicle plate (identification plate) to a trailer, you are certifying that it meets the Road Vehicle Standards Act 2021 or Motor Vehicle Standards Act 1989 (dependent on when the trailer is provided to market). Do not affix a trailer plate and do not assign a VIN to a trailer that exceeds dimension limits and / or does not meet any aspect of the applicable Act.

Non-standard trailers will be reported directly to the Department of Infrastructure, Transport and Regional Development and Communication. It is an offence to supply a vehicle to the market that does not meet the Road Vehicle Standards Act 2021 (or up to 30 June 2021, the Motor Vehicle Standards Act 1989.

Interstate VIN requests

A light trailer VIN will not be issued to a manufacturer or individual based interstate. If you reside interstate, you must contact the registration authority in your jurisdiction.

Manufacturer errors or duplicate VINs

A trailer VIN describing a particular trailer type must not be allocated to a different trailer type. VicRoads may refuse registration where it is identified that the incorrect type of VIN is assigned to a trailer. For example, a ‘box trailer’ VIN must not be allocated to a caravan.

When a manufacturer has made an error, or a VIN is duplicated on more than one trailer, the customer will be referred back to the manufacturer. When a consistent pattern of poor quality control is evident, VicRoads may refuse to issue any further VINs to a manufacturer.

VIN stamping

A VIN must be stamped, embossed or otherwise permanently marked on a substantial part of a trailer's frame or chassis (eg. drawbar).


You can apply for up to four low-volume VINs per calendar year for homemade trailers (External link).

Trailer manufacturers may request five to 50 VINS per application. 

VicRoads can only issue a maximum of 500 VINs per trailer manufacturer for each calendar year. If you estimate that you will require more than 500 VINs during the calendar year, you should contact the National Vehicle Identification Coordinator at the NEVDIS Administration Unit.

Rejecting applications

VicRoads reserves the right to reject an application if incorrect, false or misleading information is provided.
