Digital identity, or electronic identity (eID), offers developing nations a unique opportunity to accelerate the pace of their national progress. It changes the way services are delivered, helps grow a country's digital economy, and supports effective safety nets for disadvantaged and impoverished populations. Though digital identity is an opportunity, it raises important considerations with respect to privacy, cost, capacity, and long-term viability. This report provides a strategic view of the role of identification in a country's national development, as well as a tactical view of the building blocks and policy choices needed for setting up eID in a developing country. The report presents a conceptual overview of digital identity management practices, providing a set of guidelines at a national level that policymakers can find helpful as they begin to think about modernizing the identity infrastructure of their country into eID. The report also provides an operating knowledge of the terminology and concepts used in identity management and an exposition of the functional blocks that must be in place. Policy considerations are referenced at the end of the report that governments can use as they contemplate a digital identity program. Given its abridged nature, the report is intended to be insightful and detailed, though not exhaustive. Several important topics related to eID are noted though deserve further discussion, including: economic and financial analysis, the development and setup of a national civil register, and cross-border aspects of eID. The building blocks, as discussed, can help ensure that a secure, robust and reliable digital identity platform can serve the development needs of a country for the foreseeable future.
