The new eCOC system allows Slovak authorities to access vehicle data electronically.
Buying a new car in the European Union is becoming more digital from July 2026, as vehicle manufacturers move away from the traditional paper Certificate of Conformity (COC) towards an electronic version, the eCOC.
The change, which also applies in Slovakia, is part of a wider EU effort to modernise vehicle administration and improve the exchange of technical data between member states. Under the new system, manufacturers provide vehicle conformity information in a structured electronic format, allowing registration authorities to access the data digitally.
A Certificate of Conformity confirms that a particular vehicle has been produced in line with EU technical and safety requirements and can be registered within the bloc. It contains important information such as the vehicle identification number (VIN), engine power, dimensions, weight, emissions data and approved tyre specifications.
Until now, the process has relied mainly on paper documents passed from manufacturers to dealers and then to vehicle owners.
