A traceable conversion record helps explain the relationship between the original chassis, added body and any approved second-stage plate.
Converter VIN Plate Evidence Pack: Approval, Invoices and Build Records: approval and identity checks
Keep the original VIN/plate photographs, body specification, fabrication records, supplier documents, approval evidence and the exact approved mass figures.
Which plates and labels are appropriate?
Record who authorised the plate artwork and when it was attached, rather than treating a print proof as approval.
UK VIN GROUP's independent label enquiry is not official approval. For a statutory converter or manufacturer plate, the responsible legal manufacturer or authority must validate the full data, production, attachment and approval requirements. The stamped chassis VIN must remain authentic and cannot be assigned by a print supplier.
Before sending your plate or label enquiry
- Identify the real registered or unregistered vehicle and photograph its permanent chassis/VIN marking.
- Confirm the conversion stage, vehicle category and relevant original and finished-build records.
- Collect verified artwork, dimensions, mass fields and issuer instructions where applicable.
- Describe whether you need an independent workshop tag or are seeking official manufacturer approval—these are not interchangeable.
How UK VIN GROUP can help your conversion workshop
Start an evidence-reviewed enquiry for unbranded workshop identification or supplementary information labels. We can discuss printing of approved customer-supplied designs but do not issue legal approvals, guarantee statutory acceptance or impersonate an original manufacturer. Enter a UK registration if present, or a genuine VIN/chassis number for an unregistered build.

Frequently asked questions
Is a build invoice the same as an IVA certificate?
No. It records commercial work rather than official approval.
What should be done if two documents show different weights?
Stop production and reconcile the difference with the converter and approval authority.
Can a customer-provided mock-up alone justify statutory printing?
No. The necessary fields need source evidence and authority.
