Digital Public Infrastructure (DPI), Definition, Components, Initiatives

Digital Public Infrastructure (DPI) is a set of open, interoperable, and scalable digital systems that enable citizens, businesses, and governments to access services efficiently. Its key components in India include Aadhaar (digital ID), UPI (digital payments), DigiLocker (document storage), CoWIN and eSanjeevani (digital health), Account Aggregator framework, UMANG, and GeM. 

Major DPI initiatives like PMJDY, UPI, India Stack, and CoWIN have transformed financial inclusion, public service delivery, and healthcare access. Together, these platforms form the backbone of India’s digital economy and inclusive development efforts.

What is Digital Public Infrastructure (DPI)?

DPI is a set of foundational digital systems and standards that are reusable across programs and sectors. Examples of foundational blocks are: unique digital identity, instant payment rails, secure data-sharing frameworks, digital document vaults, and open APIs that allow public and private services to plug in and interoperate. The World Bank, UN agencies and major foundations describe DPI as infrastructure analogous to roads or power. This enabler lowers the cost of delivering public and private services and widens access.

Components of Digital Public Infrastructure

Digital Public Infrastructure generally consists of three core layers: Digital Identity, Digital Payments, and Data Exchange, along with supporting platforms such as digital document systems, authentication tools, and open APIs.

• Digital Identity Systems: These are secure and unique digital identification frameworks that allow citizens to authenticate themselves across multiple services. Example: Aadhaar in India.
• Digital Payment Systems: This component provides real-time, low-cost, and interoperable digital payment rails. It supports seamless transactions for individuals, businesses, and government bodies, helping transition economies toward cashless systems. Example: India’s UPI
• Consent-Based Data Sharing Frameworks: These systems allow individuals to securely share their personal data with full consent and transparency. Example: India’s Account Aggregator Framework
• Digital Document and Verification Platforms: These platforms store, issue, and verify digital documents such as certificates, licences, and government-issued IDs. Example: India’s DigiLocker
• e-KYC and Digital Onboarding Systems: These systems verify user identity digitally, enabling instant onboarding for services like banking, telecom, and digital platforms.
• Open APIs and Interoperability Frameworks: These are standardised digital interfaces that allow different systems, public and private to connect, exchange information, and build new services on top of existing digital rails. Examples include India Stack APIs, API Setu.

Digital Public Infrastructure Evolution

Digital Public Infrastructure (DPI) evolved from individual e-government projects to holistic, horizontal platforms that multiple programs reuse.

• Siloed services (pre-2010s): separate portals and databases with limited interoperability.
• Platform thinking (2010s): India pioneered large foundational projects: Aadhaar (digital identity) and open API thinking (India Stack).
• Scale & network effects (2015–2025): layering payments (UPI), drawers for documents (DigiLocker), health platforms (CoWIN), and data-sharing frameworks (Account Aggregator) turned components into an ecosystem that firms and governments can build on.
• Global DPI discourse (2020s): multilateral institutions (World Bank, UN, Gates Foundation) have adopted DPI as a development priority and produced guidance on governance, inclusion and risk mitigation.
