Because 321COC maintains direct manufacturer relationships and uses secure data exchange, customers benefit from:

• Guaranteed authenticity – all certificates are manufacturer-approved and verifiable.
• Full EU & UK acceptance – no need for additional inspections or translations.
• Rapid, transparent processing – your COC is validated and tracked from source to delivery.
• Peace of mind – every document is backed by 321COC’s accuracy and reissue guarantee.

A genuine Mercedes Benz Certificate of Conformity (COC) is an official document that contains more than 90+ verified data points proving your vehicle complies with all EU type-approval and environmental regulations. Each field is carefully defined in European Directive 2007/46/EC (and Regulation EU 2018/858), ensuring consistency across all manufacturers.

• Vehicle Identification Number (VIN) – your car’s unique chassis number
• Type-Approval Number – official EU code confirming compliance with safety and emission standards
• Variant and Version – identifying specific configuration and technical build
• Engine and Transmission Data – engine capacity, power output, fuel system, and gearbox details
• CO₂ Emissions and Environmental Class – key data for taxation, registration, and import compliance
• Mass, Dimensions, and Axle Weights – used for roadworthiness and load certification
