Finland Announces Suomi.fi EUDI Wallet - Nordic Digital Leadership

Finnish government announces Suomi.fi EUDI Wallet extending complete e-services platform.

Suomi.fi: Finland's complete Digital Government Platform

The Suomi.fi platform represents Finland's unified approach to digital government services, providing citizens, businesses, and organizations with a single gateway to all public-sector online services. Unlike many countries where government services are scattered across dozens of separate websites and portals, Finland has consolidated its digital service offering under the Suomi.fi umbrella. The platform includes Suomi.fi e-Identification (strong electronic identification), Suomi.fi e-Authorizations (managing authorizations and mandates), Suomi.fi Messages (secure digital messaging with authorities), and Suomi.fi Data Exchange (standardized data sharing between organizations).

This complete platform approach provides a natural foundation for the EUDI Wallet. Rather than building a wallet as an isolated application, Finland can extend the existing Suomi.fi ecosystem with verifiable credential capabilities. Citizens who already use Suomi.fi e-Identification to authenticate for government services will be able to store and present additional credentials - driving licences, educational qualifications, professional certifications - through the same trusted infrastructure. This integration-first approach minimizes the adoption barrier and ensures that the wallet delivers immediate practical value from day one.

The Suomi.fi platform is used by virtually all Finnish government agencies, municipalities, and a growing number of private-sector service providers. Over 2,500 organizations are connected to the Suomi.fi e-Identification service, providing a vast ecosystem of services that the EUDI Wallet can immediately interact with. This existing service provider network gives Finland a significant advantage in wallet deployment, as the relying party infrastructure is already in place and operational.

DVV: Digital and Population Data Services Agency

The DVV (Digi- ja vaestotietovirasto, or Digital and Population Data Services Agency) is the Finnish government agency at the center of the EUDI Wallet implementation. DVV was formed in 2020 through the merger of the Population Register Centre and the Local Register Offices, combining population data management with digital service development under a single organizational roof. This merger was strategic, recognizing that digital identity and population data are inextricably linked and should be managed together.

DVV manages Finland's Population Information System (VTJ), which contains the official identity data for all Finnish citizens and permanent residents. The agency also operates the Suomi.fi platform, issues electronic identity certificates, and coordinates the Finnish Trust Network that enables strong electronic identification across multiple identity providers. This combination of responsibilities makes DVV uniquely positioned to lead the EUDI Wallet development, as it controls both the source of identity data and the digital infrastructure that delivers identity services to citizens.

For the EUDI Wallet specifically, DVV is responsible for defining the technical architecture, coordinating with identity providers, conducting security assessments, and ensuring compliance with the eIDAS 2.0 regulation. The agency brings deep institutional knowledge of digital identity systems, having operated Finland's electronic identification infrastructure for over a decade. DVV's dual expertise in population data and digital technology ensures that the EUDI Wallet is built on a solid foundation of verified identity data and strong technical infrastructure.

The Finnish Trust Network: Multi-Method Strong Authentication

Finland's digital identity ecosystem is built on the Finnish Trust Network (Luottamusverkosto), a framework that enables multiple identity providers to offer strong electronic identification services through a standardized interface. The Trust Network operates through the Suomi.fi e-Identification service, which acts as a broker between service providers and identity providers. When a citizen needs to authenticate, they choose their preferred identity provider from a list that includes all major Finnish banks, mobile operators, and the electronic identity card.

Bank-based identification is the most widely used authentication method in Finland. Citizens can use their online banking credentials from banks such as Nordea, OP Financial Group, Danske Bank, and others to authenticate for both government and private services through the Trust Network. This approach uses the strong identity verification that banks perform when opening accounts, effectively outsourcing identity proofing to the banking sector. The convenience of using existing banking credentials has driven high adoption rates, as citizens do not need to obtain separate identity tokens or certificates.

The Finnish Trust Network provides a model for how the EUDI Wallet might operate in practice. The multi-provider approach, where citizens can choose among several identity providers, aligns with the EUDI principle that citizens should have choice and control over their digital identity. The Trust Network's standardized interface ensures interoperability between providers, a requirement that mirrors the EUDI mandate for cross-border wallet interoperability. Finland's decade-long experience operating this multi-provider trust framework provides valuable lessons for the EU-wide EUDI ecosystem.

Finnish Mobile Certificate: SIM-Based Digital Identity

The Finnish mobile certificate (mobiilivarmenne) is a distinctive feature of Finland's digital identity space. Provided by Finnish telecom operators including Telia, Elisa, and DNA, the mobile certificate stores the citizen's private key on a special cryptographic SIM card. When authentication or a digital signature is required, the citizen enters a PIN on their phone, and the SIM card performs the cryptographic operation locally without transmitting the private key over the network. This approach provides strong security comparable to hardware-based authentication tokens while using the citizen's existing mobile phone.

The mobile certificate has been available since the early 2010s and has been used by hundreds of thousands of Finnish citizens for authentication and digital signing. Its legal status as a qualified electronic signature creation device (QSCD) under the eIDAS regulation means that signatures created with the mobile certificate have full legal validity, equivalent to handwritten signatures. This existing QSCD capability is particularly relevant for the EUDI Wallet, which requires qualified electronic signature functionality for certain credential operations.

However, the mobile certificate faces a transitional challenge. The technology relies on physical SIM cards, while modern smartphones increasingly use embedded SIMs (eSIM) that do not support the cryptographic functions required by the mobile certificate. This technological shift means that the mobile certificate in its current form may not be viable long-term, making the EUDI Wallet's app-based approach a natural successor. The wallet can provide equivalent security through smartphone-native secure elements while eliminating the dependency on special SIM cards, potentially increasing accessibility and convenience.

Nordic eID Cooperation and Cross-Border Identity

Finland has been actively involved in Nordic eID cooperation initiatives that predate the EUDI framework by several years. The Nordic countries (Finland, Sweden, Denmark, Norway, and Iceland) have long recognized the need for cross-border digital identity recognition to support the free movement of people and the integrated Nordic labor market. These initiatives have explored practical solutions for enabling citizens of one Nordic country to authenticate and access services in another Nordic country using their national digital identity.

The Nordic cooperation has produced concrete results, including pilot projects for cross-border authentication between Finland and Estonia (facilitated by Estonia's X-Road infrastructure and Finland's Suomi.fi platform), as well as Nordic-Baltic collaboration on digital identity standards. These cross-border projects have generated practical experience with the challenges of interoperability - different national identity schemas, varying assurance levels, and the legal complexities of recognizing foreign digital identities. This experience is directly applicable to the EUDI Wallet, which aims to solve these same challenges at a European scale.

Finland's geographic and cultural position at the intersection of the Nordic and EU digital identity ecosystems gives it a unique perspective on the EUDI Wallet. Finnish stakeholders understand both the promise and the difficulty of cross-border digital identity from firsthand experience. This understanding informs Finland's approach to the EUDI Wallet implementation, which emphasizes practical interoperability testing and realistic timelines over ambitious feature commitments. The December 2026 deadline is being treated seriously by DVV, with a phased rollout plan that prioritizes core wallet functionality (identity verification and credential presentation) before adding more advanced features like qualified electronic signatures and organizational credentials.

Digital Identity in the Arctic Region

Finland's EUDI Wallet implementation also has implications for digital identity in the broader Arctic region. As the northernmost EU member state, Finland serves as a bridge between the EU digital identity ecosystem and the Arctic nations. The country's experience with digital government services in remote and sparsely populated regions provides valuable lessons for deploying digital identity in areas where internet connectivity is limited and travel distances to physical government offices are long.

In northern Finland, Lapland specifically, citizens may live hundreds of kilometers from the nearest government office. Digital identity and e-government services are not merely convenient for these citizens - they are essential for accessing basic government services without undertaking arduous and time-consuming journeys. Finland's experience ensuring that Suomi.fi services work reliably in areas with variable internet connectivity (including the use of offline-capable features and low-bandwidth interfaces) informs the EUDI Wallet's design to function in less-than-ideal network conditions.

The Sami population, indigenous to northern Finland (as well as parts of Sweden, Norway, and Russia), presents additional considerations for digital identity. Cross-border Sami communities need identity solutions that work across national boundaries, a requirement that aligns naturally with the EUDI Wallet's cross-border capabilities. Finland's sensitivity to these cross-border and minority identity needs demonstrates the country's nuanced approach to digital identity that considers not just the majority population but also communities with specific requirements. This inclusive perspective ensures that Finland's EUDI Wallet serves all residents equitably, regardless of their geographic location or cultural background.
