What is EU type approval? (and how the COC proves it)
Updated 2026-07-23 · 6 min read
EU type approval is the official procedure by which an approval authority certifies that a vehicle type meets the safety, environmental and technical requirements set out in EU Regulation (EC) 2018/858. Once a model is type-approved, every unit built to that specification can be sold and registered across the European Union without individual national testing, and the Certificate of Conformity (COC) is the document that proves each specific vehicle belongs to that approved type.
How does EU type approval work?
A manufacturer submits a representative vehicle and its technical file to a national approval authority (for example the KBA in Germany or the DVSA in the UK). The authority, with the help of an accredited technical service, tests the model against dozens of EU regulations covering brakes, emissions, lighting, crash safety and more.
If the model passes, the authority issues a type-approval number. That single approval then covers every identical vehicle the manufacturer produces, which is why mass-produced cars do not each need their own individual test before registration.
How does the COC relate to type approval?
Type approval applies to a whole vehicle type; the Certificate of Conformity applies to your one specific car. The COC is the manufacturer's signed statement that your vehicle, identified by its VIN, was built in conformity with the approved type.
This is why registration authorities across the EU accept a COC without re-testing the car: it links your individual vehicle back to an approval that has already been granted at EU level. The COC lists the type-approval number alongside the vehicle's technical data.
What is the difference between type approval and individual approval?
Type approval covers series production, so a standard EU car simply needs its COC at registration. Individual approval is a separate, single-vehicle route used for cars that do not have EU type approval, such as many non-EU imports or heavily modified vehicles.
Individual approval means a full inspection of that one car, which is slower and more expensive than presenting a COC. If your car is an EU-type-approved model, sourcing the COC is almost always the faster and cheaper path.
Key takeaways
- EU type approval certifies a vehicle model against EC 2018/858, so units built to that spec need no individual national test.
- The COC links your specific VIN to that approved type, which is why authorities accept it without re-testing.
- Cars without EU type approval need individual approval, a costlier single-vehicle inspection.
- The type-approval number appears on the COC alongside your vehicle's technical data.
Frequently asked questions
Is type approval the same as a COC?
No. Type approval covers a whole vehicle model; the COC is the per-vehicle document proving your specific car conforms to that approved type.
Who grants EU type approval?
A national approval authority such as Germany's KBA, working with accredited technical services. Manufacturers apply for it, not owners.
Do I need type approval to register my car?
You do not apply for it yourself. If your model is already EU type-approved, you just present its Certificate of Conformity at registration.
Where is the type-approval number on my car?
It is listed on the COC and often on the manufacturer's type plate. Coceu can source the original COC by VIN if you do not have it.
