A caravan VIN check starts by matching the permanent identifier on the van with its documents. The official RAV public lookup is free to access and checks recorded approval information where applicable. It does not replace a PPSR search: the official online PPSR vehicle search costs $2 and answers a different question about recorded security interests.
Which caravan checks are free?
| Check | Cost | Purpose and limit |
|---|---|---|
| Match the physical VIN and documents | No search fee | Identify discrepancies. Matching characters do not prove ownership or condition. |
| Official RAV public search | Free public access | Look up approval information for the VIN. It is not a finance, theft or condition check. |
| State or territory registration check | Basic checks may be free; confirm the authority’s service | Check recorded registration details. This does not replace PPSR or an inspection. |
| Official PPSR vehicle search | $2 online; $7 assisted phone service | Search recorded security interests. Vehicle history information may also be supplied, but can be incomplete. |
Fees checked on 5 September 2026. For a NSW-registered caravan, for example, Service NSW offers a free registration check. Use the authority for the caravan’s registration jurisdiction and confirm which details its service returns.
A search advertised as a “free caravan VIN check” is not automatically a complete history check. Use the official links and identify exactly what record is being searched. Follow our step-by-step PPSR caravan guide for the paid certificate and how to interpret it.
How to run the RAV lookup
- Photograph and copy the permanent VIN from the actual caravan.
- Open the official RAV public search and enter the VIN carefully.
- Compare the returned make, dates and recorded specifications with the caravan and paperwork.
- Save the result and search date in the purchase folder.
- If nothing is returned, first recheck the identifier and whether the caravan was supplied under the RAV system.
No result does not by itself mean an older caravan is illegal. The previous system’s transition ended on 30 June 2023; the Department’s historical approvals page explains the change. For unresolved records, contact the supplier and relevant authority before proceeding. Do not alter the identifier or accept another van’s record.
What is a VIN?
A Vehicle Identification Number is the unique identifier assigned to a road vehicle. Current low-ATM trailers use a 17-character VIN. Older caravans may also be described by a chassis number or identification number, depending on age and the system used when supplied.
Copy the identifier directly from the caravan rather than relying on an advertisement. Check every character carefully; letters and numbers can be confused.
Match the identity in four places
- The permanently marked identifier or vehicle plate on the caravan
- The sales contract and tax invoice
- Registration or transfer documents
- The relevant government record, including the RAV for vehicles supplied under the current system
Also compare make, model, build date, ATM, GTM and tare where those fields are shown. Stop when an identifier or material rating does not agree. Ask the supplier and relevant authority to resolve the discrepancy in writing before payment or towing.
What is the Register of Approved Vehicles?
The Register of Approved Vehicles is the Australian Government’s public database for vehicles supplied under the Road Vehicle Standards framework. It is searched using the VIN and can show the entry date, approval pathway, approval number, approval holder, make, model, build date and mass information.
From 1 July 2023, the transition to the current arrangements required relevant manufacturers and importers to use Road Vehicle Standards approvals before first supply, with vehicles entered on the RAV. Older caravans may sit under earlier arrangements, so absence from the current RAV is not by itself proof that an older caravan is unlawful.
Vehicle type approval and concessional entry
A manufacturer or importer supplying more than a small number of low-ATM trailers normally uses a vehicle type approval. A concessional RAV entry pathway can apply to limited individual supply. These are approval pathways for suppliers; a buyer’s practical job is to verify that the exact completed caravan has the expected RAV entry and matching information.
What VSB 1 Revision 6 means to a buyer
Vehicle Standards Bulletin 1 Revision 6 helps manufacturers and importers understand the Australian Design Rule requirements applying to trailers with an ATM of 4.5 tonnes or less. The August 2026 edition is current at the time of review.
For buyers, the useful checks are straightforward: verify the VIN, vehicle plate and RAV details; ask for the manufacturer’s specifications; and have the physical caravan inspected. VSB 1 is not a substitute for inspecting workmanship, modifications, water entry or running gear.
What the vehicle plate should tell you
For current trailers, VSB 1 specifies information including manufacturer or make, VIN, ATM, GTM and tare on the vehicle plate. The mandatory details should match the information entered on the RAV. The plate may also show tyre information, model and build date.
Do not calculate payload from a plate you cannot read or from details belonging to another model. Use the exact caravan’s documents and confirm how dealer or post-build options affect its real starting mass.
Older, imported or unusual caravans
Older vehicles, individually imported caravans and home-built or modified trailers can involve different historical records and state or territory registration requirements. Ask the registration authority where the caravan is or will be registered which records and inspections apply. Do not attempt to “fix” an identifier yourself.
Warning signs
- The VIN is missing, damaged, altered or hard to reconcile.
- The plate and paperwork show different identifiers or ratings.
- The seller will not provide a VIN before a deposit.
- The RAV result belongs to a different make, model or mass.
- The build date or model year differs from the contract without explanation.
- Major modifications are not supported by engineering or registration evidence where required.
- The seller says registration will “sort itself out” after payment.
RAV does not answer every buying question
A matching RAV record does not prove there is no finance owing, that the caravan has not been stolen or written off, or that it has no recall or defect. For a used caravan, also complete a PPSR vehicle search, search recalls and obtain an appropriate inspection.
It also does not prove the caravan can be safely towed by your vehicle. Use manufacturer ratings and real loaded measurements through the Weights & Towing hub.
Before final acceptance
- Photograph the VIN, plate and caravan.
- Search the VIN on the RAV where applicable.
- Save the RAV result with the contract and invoice.
- Match make, model, dates and masses.
- Resolve discrepancies before final payment or registration.
- Continue with the Buying a Caravan hub.
