Caravans may use a CRIS identifier alongside or as their relevant chassis identity for records or trailer registration.
Caravan CRIS, VIN and Chassis Identification: Label Guide: identify the trailer correctly
Preserve manufacturer serial photos and match them against existing caravan documents; older caravans may use non-standard formats.
Trailer number, approval and weight limitations
Do not lengthen, shorten or invent serial digits to make a form accept a caravan identifier.
Trailer registration, type approval and original statutory markings are separate procedures. The responsible maker and authorities determine approval or any replacement of official identity; an independent vehicle-label printer cannot make a trailer legal by adding a serial or load-rating sticker.
Trailer inspection evidence checklist
- Photograph the permanent original TIN/VIN or chassis serial and any existing manufacturer plates.
- Identify the trailer category, actual approved gross mass, axle arrangement and authentic paperwork.
- Retain builder certificates, import records, invoices and the reason for any lost or damaged label.
- Check the prescribed plate format, placement, durability and approval route before commissioning official markings.
UK VIN GROUP — trailer identification-label enquiries
We can review independently labelled auxiliary asset tags, workshop stickers or lawful customer-supplied information after verifying the genuine vehicle identity. We cannot allocate a trailer VIN/TIN, issue an IVA certificate, invent mass ratings or claim that a generic plate is manufacturer-approved. Use the genuine trailer identifier in the enquiry; the UK registration box is optional for unregistered trailers.

Frequently asked questions
Can a caravan CRIS number be relevant to trailer registration?
Yes. GOV.UK guidance recognises some CRIS numbers in its trailer registration process.
Does every older caravan have a modern 17-character VIN?
No. Age and maker's serial conventions can differ.
Can an independent replacement sticker certify ownership?
No. It is not a substitute for legitimate ownership or official record evidence.
