SEAT COC

A Certificate of Conformity (COC) is an official document that can only be issued by the vehicle's manufacturer. Since the COC contains precise technical details about the vehicle at the time of its production, only the original manufacturer has access to the necessary data to generate this document.

As an authorized intermediary, 321COC provides authentic and official COCs that are valid across all EU and EEA countries, including Switzerland. Each COC is obtained directly from the manufacturer or its official representative, ensuring its compliance with European regulations.

Each Certificate of Conformity (COC) is unique and directly linked to the Vehicle Identification Number (VIN) of the specific vehicle. Typically, a COC consists of 51 technical points, each detailing key specifications of the vehicle, such as engine type, emission standards, weight, dimensions, fuel consumption, and more.

For reference, you can explore some of our COC samples, which are available on each brand page. These include examples for passenger cars (e.g., Volkswagen, Audi).

A Certificate of Conformity (COC) is an official document that certifies a vehicle's compliance with its EC type approval. This certification facilitates the unrestricted movement of goods across the European Union, particularly for vehicles that require homologation and registration. We provide COCs for the following vehicle categories:

• Passenger cars (M1)
• Light commercial vehicles (N1)
• Motorcycles (L)

The COC serves as a manufacturer's declaration that a vehicle meets the approved type specifications. It includes key details such as the vehicle's identification, manufacturer information, type approval number, technical specifications, and other essential data. The format and content of a COC are regulated by EU legislation (Amendment IX, Regulation 92/53)

If you have imported a vehicle from another country, many jurisdictions require a Certificate of Conformity (COC) to verify that the vehicle complies with the necessary technical and environmental standards for registration and road use without modifications.

However, in certain cases, if key details—such as technical specifications or approval codes—are already documented in the vehicle’s paperwork, a COC may not be required. That said, authorities might still request it as part of the registration process.

Since registration requirements for imported vehicles differ from country to country, you can find more details on specific national regulations here.

The cost of a Certificate of Conformity (COC) online depends on several factors, including the vehicle’s make, model, country of origin, and year of first registration. Prices vary accordingly, with luxury and high-end brands generally having higher fees.

All our COC documents are official originals, issued either by the vehicle manufacturer or an authorized representative of the brand. However, the first copy of the document is considered the true original and is intended for the vehicle’s first owner. Any additional copies may be marked as “Duplicate” or “Copy”, but they retain full validity as a Certificate of Conformity, including all security features such as a hologram, watermark, or signature.

A Certificate of Conformity (COC) is an official document detailing the technical specifications of a specific vehicle. It includes essential information such as the VIN number, vehicle color, number of seats, emission standards, fiscal power, sound level, engine capacity, maximum speed, fuel type, fuel consumption, and gearbox type.

Unlike a registration certificate, a COC typically contains 51 technical points, covering all necessary data for compliance verification. If you would like to see what details are included in a Certificate of Conformity, feel free to check the EU legislation - Annex IV.

The initial issuance of a Certificate of Conformity (COC) is typically provided free of charge when purchasing a brand-new vehicle directly from an authorized dealer. However, if you are buying a pre-owned car, second-hand vehicle, light commercial vehicle, scooter, or motorcycle, the original COC has most likely already been issued to the first owner. Any subsequent copy, referred to as a duplicate, is subject to a fee. 

Since the vehicle manufacturer maintains the official database for COC records, they charge a mandatory fee for each additional copy. As a result, there is always a cost associated with obtaining a COC. Be cautious of free COCs available online, as these are likely to be invalid or unofficial and may not be accepted for vehicle registration.

The Certificate of Conformity (COC) was introduced as part of the European Union’s mission to ensure the free movement of goods and services within its single market. The EU internal market was officially launched in 1993, allowing products approved under EU regulations to be traded freely without requiring additional approvals—this principle also applies to vehicles.

Previously, vehicles had to be approved individually by each EU Member State. However, with the adoption of the new legislation (92/53/EEC, 2007/46/EC), a unified European vehicle approval system replaced national approval processes. This European type-approval sets technical standards for all new vehicles, making it easier to register, sell, and use them across EU countries.

One of the key advantages of this system is the elimination of multiple national approvals, reducing bureaucracy while ensuring high safety and environmental protection standards. The Certificate of Conformity (COC) serves as official proof that a vehicle complies with all EU regulatory requirements.

The Ultra Low Emission Zone (ULEZ) in Central London enforces strict emissions standards, requiring vehicles to meet specific criteria to operate without incurring additional charges. This initiative aims to reduce pollution and improve air quality in the city.

To stay compliant and avoid fines, ensure your vehicle meets the ULEZ emission standards. If your car does not qualify, you may need to pay a daily charge or consider alternatives such as upgrading your vehicle or applying for exemptions if eligible.

Let us help you navigate the ULEZ requirements seamlessly. Stay informed and compliant with us!

If your vehicle was first registered outside the European Union, obtaining a Certificate of Conformity (COC) is not possible. This is because such vehicles do not comply with European standards and lack a European type-approval number required for COC issuance.

In this case, you should contact the importer or the official brand representative in the country where you plan to register the vehicle. They will guide you on the necessary steps for registration, as the process may vary depending on the specific country.
