You need a Certificate of Conformity to register your car. You contact the manufacturer. They tell you they cannot issue one, or they simply do not respond. It is a situation that leaves thousands of car owners stranded every year, stuck between a vehicle they legally own and a registration system that demands a document the manufacturer refuses to provide.
Whatever the reason given, the result is the same: you are without the one document that most EU registration authorities treat as the foundation of the entire registration process.
This guide explains why manufacturers refuse COC requests, what your legal rights actually are, and what practical steps you can take to move forward.
Understanding the reason for the refusal matters, because different reasons lead to different solutions. There are five main scenarios.
Manufacturers are not legally required to retain production records indefinitely. For vehicles produced more than 15 to 20 years ago, the relevant documentation may have been archived in formats that are no longer accessible, transferred to a successor company without complete data migration, or simply destroyed as part of standard records management.
This is particularly common with brands that have been acquired, merged, or restructured. A Rover, a Saab, or an early Chrysler product may have been built by a company that no longer exists in any recognisable form, leaving no entity with both the legal responsibility and the operational capability to issue a COC.
If the car was originally manufactured for the US, Japanese, Middle Eastern, or any other non-EU market, it was never type-approved under EU regulations. No EU COC was ever issued for it, because none was ever required. The manufacturer cannot issue a document certifying EU compliance for a vehicle that was not built to EU standards.
This is distinct from a lost COC — it is a COC that never existed.
Even for vehicles that were legitimately built for the EU market, the VIN may not appear in the manufacturer’s current database. This happens when older VIN formats were not migrated to new systems, when vehicles were produced under a sub-brand or contract manufacturer arrangement, or when fleet and special-order vehicles were registered under different documentation processes.
In these cases, the manufacturer’s response is a genuine database failure rather than a policy refusal — but from your perspective, the outcome is identical.
Some manufacturers, or more commonly their national subsidiaries, simply have no process in place for issuing duplicate COCs. This is especially common in markets where COC requests from private owners are rare — where most vehicles stay registered in the country of original sale and the COC is never needed after the first registration.
When you contact a manufacturer in this situation, you may be told that COCs are only issued to authorised dealers, or only at the point of original sale, or that the manufacturer “does not provide this service.” The refusal is a policy decision, not a legal impossibility.
For vehicles produced at the transition between two regulatory eras — for example, between the NEDC and WLTP emissions testing regimes — manufacturers sometimes decline to issue COCs for older variants because the technical data on file no longer aligns neatly with current documentation formats. This is relatively rare but does occur, particularly for vehicles produced between 2017 and 2019.
Before exploring alternatives, it is worth being clear on what EU law actually says about the manufacturer’s obligations.
EU Directive 2007/46/EC — replaced by Regulation (EU) 2018/858 for vehicles type-approved from September 2020 — establishes that manufacturers must issue a Certificate of Conformity for every vehicle produced under an EU type approval. Regulation 2018/858 states explicitly that the manufacturer shall provide the buyer of each new vehicle with a certificate of conformity, free of charge, accompanying the vehicle.
The word “new” is the operative limitation. The legal obligation applies at the point of sale of a new vehicle. There is no explicit statutory obligation requiring manufacturers to issue replacement COCs for existing vehicles on demand, years or decades after the original sale. This is the gap that leaves so many owners without a clear legal remedy when a manufacturer refuses.
This is the fastest and most effective solution for the majority of cases — particularly where the refusal is based on policy rather than a genuine absence of records.
Specialist services like auto-coc.eu have direct access to manufacturer databases and type approval archives that are not accessible through standard customer service channels. Where a manufacturer’s public-facing support team cannot or will not process a COC request, these services work through technical and commercial channels that bypass the standard refusal pipeline.
The service covers over 90 vehicle brands, including models from manufacturers that have been acquired or restructured, and can verify availability for your specific VIN before you commit to payment. The document delivered is an official COC — not a copy, not a summary, not a substitute — valid for use in any EU registration process.
For vehicles where the manufacturer has a policy of not issuing replacements to private individuals, this route resolves the problem in days rather than the weeks or months that direct manufacturer contact typically involves — when it produces a result at all.
EU type approvals are granted by national approval authorities — the Kraftfahrtbundesamt (KBA) in Germany, the Vehicle Certification Agency (VCA) in the UK pre-Brexit, the DRIRE in France, the RDW in the Netherlands, and so on. These authorities retain records of all type approvals granted under their jurisdiction.
If your vehicle was manufactured under a type approval held by a national authority, you can contact that authority and request the technical data sheet associated with your vehicle’s type approval. This will not be a COC — it is a different document — but it contains much of the same technical data that registration authorities need. Some EU registration systems accept this as an alternative to the COC, particularly for older vehicles.
This route requires knowing which national authority holds the type approval for your vehicle. The type approval number is usually printed on the COC itself (which you may not have) or can sometimes be found on the vehicle’s compliance plate, typically located on the door jamb.
If no COC exists and no technical data can be obtained from the manufacturer or type approval authority, the formal alternative is Individual Vehicle Approval — a vehicle-specific technical assessment carried out by an authorised inspection body in your destination country.
IVA is the established route for importing vehicles from outside the EU, but it is also available for EU-origin vehicles where type approval documentation is unavailable. The vehicle is assessed point by point against the relevant EU standards, and a national approval is issued that allows registration to proceed.
The downsides of IVA are significant: it is time-consuming (typically several weeks to several months), expensive (costs vary by country but can run to several hundred euros), and the outcome is not guaranteed if the vehicle has technical characteristics that do not meet current standards. Modifications may be required before approval is granted.
IVA should be treated as a last resort — the option you pursue when the COC genuinely cannot be obtained through any other means.
If your vehicle is 30 years old or older, you may be able to bypass the COC requirement entirely by registering it under the historic vehicle category. Most EU member states have a specific registration stream for historic vehicles that does not require a COC and applies relaxed technical standards reflecting the vehicle’s original specification.
This route requires that the vehicle is in a substantially original condition — significant modifications can disqualify it from historic status. A FIVA (Fédération Internationale des Véhicules Anciens) identity card, while not universally required, significantly strengthens a historic vehicle registration application and is recognised across EU member states.
For owners of classic cars who have been struggling to obtain a COC for a vehicle at or approaching the 30-year threshold, this option may be the cleanest available — particularly if the alternative is an expensive and uncertain IVA process.
If you have received a refusal from a national subsidiary, do not accept it as final. National branches often have different policies and database access than the parent company. A refusal from BMW France does not necessarily mean the same answer from BMW AG in Munich.
For the vast majority of owners whose manufacturer has refused a COC request — whether due to policy, outdated systems, or a simple failure to respond — the fastest practical resolution is a specialist retrieval service.
Start at auto-coc.eu, enter your VIN, and verify whether your vehicle’s COC is retrievable through technical channels that bypass the standard customer service refusal. If it is, you will have the document in days. If it is not — because the vehicle genuinely falls outside EU type approval — the service will tell you that too, saving you the time of pursuing a path that will not produce the result you need.
Either way, you will know where you stand and what your next step is. That clarity, when you are stuck in a documentation impasse, is worth a great deal.
