As the EU moves to fully electronic Certificates of Conformity (eCoC) by July 2026, manufacturers are required to sign these documents using compliant electronic signatures, specifically in XML format.
What Is XAdES?
XAdES (XML Advanced Electronic Signature) is the signature format required when signing structured XML documents like eCoCs and Initial Vehicle Information (IVI).
Unlike PDF-based signing, XAdES works inside the XML structure itself, making it verifiable, machine-readable, and suitable for long-term validation — even years after the signature was created.
Why XAdES for eCoC?
- It’s the standard required under Regulations (EU) 2021/133 and 2024/1061
- It works natively with XML-based vehicle data structures
- It ensures your eCoC remains valid and verifiable for 10+ years
- It supports Advanced and Qualified eSignatures and eSeals — as required by eIDAS
Whether you're submitting to a national registration system or through EUCARIS, XAdES ensures your signature is trusted and accepted across the EU.
