Over one billion people, including many millions of children, women and refugees, globally lack any form of officially recognized identification. Without an identity, individuals are often invisible – unable to vote, access healthcare, open a bank account, or receive an education – and bear higher risk for trafficking. Without accurate population data, public and private organizations struggle to broadly and accurately deliver the most basic human services. The ID2020 Alliance is a global partnership bringing together governments, NGOs and the private sector to address this challenge. The consortium approach ensures that technology development is informed by the needs of countries and individuals, and that policies and standards reflect the latest technological innovations. By coordinating funding for identity and channeling those funds towards high-impact projects, this alliance model enables diverse stakeholders - UN agencies, NGOs, governments, and enterprises - to pursue a coordinated approach and creates a pathway for efficient implementation at scale.
