Certificate of conformity by make Mercedes-Benz

Mercedes-Benz covers two very different worlds in our files. On one side the passenger cars — A-Class, C-Class, E-Class, GLA, GLC — where the procedure is straightforward. On the other, one of the most heavily converted commercial ranges in Europe.

A Sprinter turned into a motorhome, a Vito converted into a shuttle, a V-Class fitted out for wheelchair transport: in every one of these cases approval was granted in several stages. Mercedes-Benz then documents only the base chassis, as it left the factory. The conversion certificate is a separate document, to be requested from the body builder who carried out the work. Tell us from the start whether your vehicle was converted: it changes what we can obtain.

The most frequent file is not a saloon but a converted commercial vehicle: a Sprinter turned into a motorhome by a German body builder, or a Vito converted into a shuttle. The buyer orders a certificate expecting a description of the complete vehicle, and receives the chassis one. We would rather say so beforehand. On a Mercedes-Benz we therefore ask up front whether the vehicle was converted after leaving the factory. If so, we obtain the base chassis certificate and tell you which document to request from the body builder, whose name usually appears on an additional plate. On passenger cars our checks focus instead on trim and tyre sizes, which vary a great deal between markets.

A Mercedes-Benz certificate is usually issued by the manufacturer’s type-approval department, centrally for the whole of Europe.

Where to find the chassis number (VIN) on a Mercedes-Benz

A certificate covers one vehicle only, identified by its chassis number (VIN). The safest place to read it is field E of the foreign registration document. On a Mercedes-Benz, it also appears:

• at the base of the windscreen, driver’s side, readable from outside
• on the manufacturer’s plate on the driver’s door pillar
• under a floor flap on the front passenger side

A VIN never contains the letters I, O or Q: mistaking one for a 1 or a 0 is enough to send the search astray.

Most frequently imported Mercedes-Benz models

The Mercedes-Benz vehicles we handle most often come from Germany, from Austria and from Belgium.

The requests we receive mostly concern:

• Mercedes-Benz Classe A
• Mercedes-Benz Classe C
• Mercedes-Benz Classe E
• Mercedes-Benz GLA
• Mercedes-Benz GLC
• Mercedes-Benz Vito
• Mercedes-Benz Sprinter
• Mercedes-Benz Classe V

The rest of the EU-approved Mercedes-Benz range is handled the same way.

Mercedes-Benz and the eCOC: what changes in 2026

Since 5 July 2026, Mercedes-Benz has been sending conformity data for its new vehicles to the approval authorities in eCOC format. Your used Mercedes-Benz is not affected: you need the ordinary COC, issued exactly as before. Paper and printouts of the eCOC remain accepted until 29 November 2026 at the latest. Understand the eCOC.
