An off-road caravan that cannot be identified cannot be registered, titled or insured — and identification is settled at the factory, not at the registration counter. Two items carry it: the vehicle identification number (VIN) marked on the unit, and the data plate fixed to it. Both belong in the purchase specification, because correcting them after the container sails is expensive.

What must be on the unit

The VIN is the 17-character identifier standardised internationally (ISO 3779), and its first three characters form the World Manufacturer Identifier allocated to the manufacturer. On a caravan it is normally stamped into the drawbar or chassis and repeated on the plate: one number per unit, never reused across a production run. The data plate is what a registration clerk or an insurer actually reads — manufacturer and model, VIN, date of manufacture, tare mass, ATM, axle or suspension rating, and tyre size and pressure. Some markets also require a separate compliance plate, fitted in addition to the data plate rather than instead of it.

Why the plate is the importer's obligation

The factory builds the unit; the importing company normally carries the registration obligation in its own market. In the United States and Canada a caravan is titled and registered by VIN at state or provincial level, so a duplicated or malformed number stops the process at the counter. In Australia, trailers within the road vehicle standards framework carry a compliance plate fitted by the manufacturer or by the importer who takes responsibility for the unit. If you are building the off-road caravans for importers side of the business, treat identification as a product cost, not as paperwork.

What to write into the order

Four points are worth writing into the specification rather than leaving to the factory's standard practice:

• VIN allocation and format. Confirm the 17-character structure, who allocates the numbers, and that every unit in the order receives its own.
• Marking position and method. Agree where the VIN sits on the chassis or drawbar and how it is applied, so it survives years of dust and pressure washing.
• Plate content, language and units. List the fields the plate must carry, in the language and units your registration authority accepts.
• Document consistency. The same VIN has to appear on the invoice, packing list and bill of lading, and in the pre-shipment photo record.

Checks before you release the balance

Before the balance is paid, ask for a photograph of the VIN stamp and the fitted plate on every unit, then cross-check them against the shipping documents and the number of units loaded. Confirm that plate figures match the published specification for the model you ordered — as they are published for the 16ft east-west off-road caravan — because a plate that disagrees with the specification sheet is a registration problem, not a typo. Where a market requires an approval or an entry certificate, confirm who applies for it; on most routes that is the importer, not the factory. Specifications vary by model and final configuration, so any change made after the plate is produced has to be re-confirmed in writing.

Get identification right and the rest of the registration file falls into place. Get it wrong and the best-specified caravan on your yard is unsellable, whatever it cost to land.
