eIDAS interoperability

eIDAS interoperability refers to the mutual recognition of digital identities and electronic signatures between EU Member States, as mandated by the eIDAS regulation (Articles 6 and 25). A qualified certificate issued by a trust service provider (TSP) listed on the trust list of a Member State is automatically recognised as valid in all other Member States — without any additional steps. This interoperability covers the AES and QES levels. eIDAS 2.0 (EU 2024/1183) extends this mechanism to the EUDI Wallet, planned for 2026.
