Will the EU Digital Identity Wallet (EUDIW) be mandatory for use in core regulated sectors in 50% of EU member states before the end of 2028?

EUDIW: Mandatory in Half of the EU by 2028?

Under the revised eIDAS 2.0 framework, every member state must provide a compliant EUDIW by late 2026, and regulated industries (like banking and telecom) must accept it by 2027. This prediction asks if 50% of member states will make its use mandatory for core sectors (e.g., accessing certain government services) by 2028.

Regulatory Momentum

The strong 'Yes' vote is based on the EU's commitment to creating a seamless digital single market. While national rollouts are proceeding at different speeds (as seen in late 2025 news), the core regulation provides the legal stick. Given the strategic importance of this project for digital commerce and security, it is highly probable that most major economies will enforce mandatory use in key national services by 2028 to meet the broader EU goal of $80\%$ citizen uptake by 2030.
