Trailer approval documents should identify the vehicle accurately and provide the technical characteristics required by the relevant scheme.
Trailer IVA Certificate, Certificate of Conformity and VIN Records: identify the trailer correctly
Keep copies of the correct certificate, maker or converter identity and chassis serial, along with sale and completion dates.
Trailer number, approval and weight limitations
For relevant UK small trailer supply rules, manufacturers must retain records and provide proper certificates; printing a plate is not the same as issuing them.
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
Is a certificate of conformity identical to a printed label?
No. It documents approval, while the plate is a separately specified marking.
Can a supplier issue an approval certificate for another manufacturer?
Only if legally authorised under the relevant scheme.
Do trailer records need retaining after sale?
Yes. Current GOV.UK small-trailer guidance specifies manufacturer record-keeping requirements.
