How eCoC, IVI, and EUCARIS Work Together

eCoC, IVI, and EUCARIS are different parts of the same digital vehicle compliance ecosystem. eCoC represents conformity information, IVI structures vehicle data, and EUCARIS supports cross-border authority exchange.

The role of eCoC

eCoC is the conformity confirmation layer. It expresses how a vehicle relates to the approved basis and how that conformity information can support downstream workflows such as registration.

The role of IVI

IVI is the structured vehicle information layer. It helps systems work with vehicle characteristics in a more consistent and machine-readable way.

The role of EUCARIS

EUCARIS is part of the exchange infrastructure used by authorities. It helps support cross-border communication of vehicle-related information without replacing national systems.

Why the combination matters

Modern vehicle compliance depends on more than one concept. The data model, the conformity logic, and the exchange layer all need to align if digital workflows are going to remain reliable.

Frequently Asked Questions

Do eCoC, IVI, and EUCARIS mean the same thing?

No. They describe different layers of the vehicle compliance ecosystem: conformity information, structured vehicle data, and cross-border exchange infrastructure.
