Large-scale welfare programs are efforts by states to improve citizens’ well-being and promote social equity. Yet, many countries struggle with systematic inefficiencies, corruption, and bureaucratic hurdles affecting their effectiveness. Digital public infrastructure (DPI) has emerged as a potential solution helping to streamline processes, minimise human error, and increase transparency. However, its impact remains an open question: Can technology genuinely overcome these systemic challenges, or does it risk exacerbating existing inequalities by reinforcing structural biases and digital divides?
India’s experience offers valuable insights into how institutional design can drive DPI success. Rather than relying on legacy agencies, India established agile, independent bodies like the Unique Identification Authority of India (UIDAI) and the National Payments Corporation of India (NPCI). This strategy balanced reforms of existing institutions with the creation of new ones, enabling rapid iteration and scalable implementation – a key factor in building trust and ensuring long-term adoption.
India’s Welfare Delivery Challenges: Setting the Stage
For decades, India’s welfare delivery system faced similar challenges – inefficiencies and corruption to siloed processes and limited accessibility – leading to significant leakage of benefits. Former Prime Minister Rajiv Gandhi highlighted the scale of this challenge when he once went on record to say that out of one rupee spent by the government on welfare schemes, only 15 paise (15%) actually reaches intended beneficiaries (1). Unlike other countries with unique identification systems, such as the Social Security Number (SSN) in the United States, India lacked a universal identity document – resulting in slow service delivery. For instance, opening a bank account could take days or weeks due to the ambiguity of various authentication documents.
The absence of a robust identification system also left India’s welfare programs vulnerable to leakages and inefficiencies. An Independent Evaluation Office (IEO) report found that 57% of subsidised food grains did not reach intended beneficiaries, and 37% were siphoned off through the supply chain (3). Addressing these deep-rooted inefficiencies required to improve transparency, reduce fraud, and enhance the efficiency of welfare distribution.
From Vision to Design
Recognising the severe gaps in welfare delivery, the Indian government initiated the “Unique ID for BPL Families” project in 2006, initially targeting economically disadvantaged households. Over time, this vision expanded to include every resident and an empowered Group of Ministers (EGoM) was formed to propose an institutional framework that could unify fragmented identity systems and standardise data collection across multiple government agencies, including the Registrar General of India and the National Population Register (NPR) (2). Consequently, the Unique Identification Authority of India (UIDAI) was formally notified on January 28, 2009, becoming the new institutional mechanism responsible for implementing Aadhaar as India’s foundational digital identity platform.
Despite its transformative potential, Aadhaar encountered resistance from several stakeholders. The Ministry of Home Affairs (MHA) initially opposed the initiative, citing jurisdictional overlap, national security concerns, and potential duplication with the NPR database (3). Political parties, particularly those in opposition and privacy advocates, also raised concerns about mass surveillance, data security, exclusion risks, and increased centralisation. However, over time, as Aadhaar enhanced the efficiency of welfare delivery, fraud reduction, and financial inclusion, opposition parties, including those that initially criticised it, adopted and integrated Aadhaar into their governance strategies. The initiative eventually became a key component of the Digital India movement, enabling seamless service delivery, direct benefit transfers (DBT), and broader financial inclusion. This political shift was crucial in securing widespread acceptance and institutional support, ultimately making Aadhaar one of the world’s most influential digital public infrastructure initiatives.
Operationalisation
The UIDAI was established in 2009 as a statutory body with the mandate to create and manage Aadhaar. Unlike traditional bureaucratic bodies, UIDAI was designed as a cross-functional institution, operating independently of existing administrative constraints while collaborating with various government departments. This silo-breaking approach ensured seamless coordination across ministries, allowing Aadhaar to be integrated into the welfare programs of multiple departments/ministries. The government later enacted the Aadhaar Act (2016) to formally establish UIDAI as a statutory body, providing it with regulatory powers and constitutional legitimacy. Today, 99.9% of Indian adults use an Aadhaar number at least once a month, underscoring its deep integration into India’s governance and digital infrastructure (4).
Aadhaar’s early success is also rooted in how it was implemented. The government appointed Nandan Nilekani, a respected technocrat and former Infosys CEO, to lead UIDAI. Under his leadership, a handpicked team of professionals from business, technology, and consulting backgrounds was assembled – people with deep expertise but limited ties to traditional government structures. This team was granted freedom to work outside bureaucratic norms, enabling a start-up-like culture within a state-led project. This non-traditional approach – distinct from legacy models – was key to Aadhaar’s clarity, speed, and success. While UIDAI was eventually reincorporated more closely into the state apparatus, its early phase demonstrated how institutional innovation and empowered teams could drive ambitious public digital infrastructure initiatives.
Additionally, unlike traditional government projects usually dependent on the public infrastructure, Aadhaar was built with extensive private sector participation, allowing for necessary scalability and implementation efficiency. For example, the government contracted private agencies to set up Aadhaar enrollment centres, enabling a decentralised, market-driven approach to data collection. This open engagement with private players significantly departed from conventional public-sector-driven models, helping UIDAI enrol over a billion residents in record time (5). Also, rather than creating new infrastructure from scratch, UIDAI strategically leveraged existing government institutions and service delivery mechanisms. For example, Banks, post offices, Common Service Centers (CSCs), and Public Distribution System (PDS) outlets were integrated into the enrollment process. The authentication framework was designed to be interoperable with existing databases used by various government programs, making Aadhaar the backbone of welfare distribution, financial inclusion, and digital governance.
Aadhaar’s identity verification mechanism also set the stage for a secure and inclusive digital payments ecosystem in India. Traditionally, the banking sector functioned with limited interoperability, where banks operated in silos, making real-time transactions difficult. Recognising these challenges, the National Payments Corporation of India (NPCI) was established to modernise the country’s financial infrastructure. Building on Aadhaar-based authentication, NPCI created the Unified Payments Interface (UPI), a real-time payment system that connects banks, digital wallets, and merchants seamlessly. By linking Aadhaar with bank accounts, NPCI enabled direct benefit transfers (DBT), reducing leakages and ensuring that welfare payments reached beneficiaries instantly. Designed as a neutral, public-private entity, NPCI has ensured no single institution dominates the ecosystem – important for trust and widespread adoption. As of 2024, the volume of daily UPI transactions has surpassed 500 million daily transactions (4).
Expanding the DPI Ecosystem
The impact of Aadhaar and the UPI extended far beyond identity verification and digital payments. By providing a secure, scalable, and interoperable DPI, Aadhaar has enabled seamless service delivery across multiple sectors.
In healthcare, Aadhaar-based biometric authentication is crucial for Ayushman Bharat, the world’s largest health insurance scheme, ensuring that benefits reach the intended recipients efficiently. Similarly, the CoWIN platform utilised Aadhaar for streamlined verification and record-keeping during COVID-19 vaccination drives. Education has also benefited, with Aadhaar-linked platforms like DIKSHA offering personalised digital learning experiences and the Academic Bank of Credits (ABC) facilitating seamless credit transfers between institutions (5). In agriculture, initiatives like eNAM (electronic National Agriculture Market) and PM-KISAN leverage Aadhaar-based Direct Benefit Transfers (DBTs) to ensure that subsidies and payments reach farmers without intermediaries, reducing corruption and improving transparency. Similarly, programs like MGNREGA, which guarantees 100 days of wage employment in rural India, now distribute payments directly through Aadhaar-linked accounts, ensuring greater transparency and timely wage disbursement. Also, the Public Distribution System (PDS), historically plagued by leakage rates exceeding 50%, was reformed through Aadhaar-linked electronic point-of-sale (ePOS) devices, ensuring that only authenticated beneficiaries receive subsidised food grains (6).
Beyond governance and service delivery, Aadhaar has also transformed India’s private sector and start-up ecosystem, especially unlocking new opportunities in fintech, e-commerce, and digital banking. By 2021, India became the third-largest start-up ecosystem globally, with 90% of new unicorns leveraging Aadhaar for authentication and digital onboarding (7). The India Stack, powered by Aadhaar, enabled paperless e-KYC, allowing financial service providers to onboard customers in minutes rather than days. This fueled unprecedented fintech growth, with India leading global fintech adoption at 87% (8) – similarly, Aadhaar-based FASTag streamlined toll payments, reducing congestion and improving transport efficiency. By integrating identity, payments, and data-sharing infrastructure, Aadhaar has become the backbone of India’s digital transformation, enabling innovation, economic inclusion, and governance efficiency at an unprecedented scale.
Learnings
India’s digital transformation journey offers critical insights for institutional innovators and policymakers.
A key lesson is the critical role of institutional autonomy and the need for institutional innovation. Being independent bodies with well-defined mandates, minimal bureaucratic constraints, and the flexibility to integrate emerging technologies, these organisations (UIDAI, UPI, ONDC, etc.) can drive rapid innovation and scalable implementation. Their ability to operate beyond the rigid hierarchies of traditional government agencies enables faster decision-making, continuous adaptation, and more effective service delivery. Equally essential is an open and interoperable architecture and their cross-sector integration. This approach encourages stakeholders to leverage common platforms while avoiding siloed operations, ensuring solutions remain agile and universally accessible. Ultimately, building these interconnected ecosystems enhances service delivery and maximises societal benefits.
India’s DPI approach also highlights the value of a data-driven, iterative implementation model. Real-time data analysis and feedback loops enabled continuous refinements and swift course corrections, allowing institutions to remain responsive to evolving user needs and technological advancements. Moreover, India’s emphasis on inclusive, equitable, and user-centric deployment ensured DPI platforms remained accessible, multilingual, and user-friendly. This effectively bridged digital divides and enabled marginalised populations to participate meaningfully in the digital economy. Lastly, the effectiveness of India’s DPI is deeply linked to robust multi-stakeholder collaboration and strategic integration across institutional functions. Active engagement with private sector innovators, civil society, and academia expanded institutional capacity, accelerated adoption, and enabled continuous innovation.
India demonstrates the value of cohesive, visionary strategies in delivering transformative digital public infrastructure through this orchestrated approach.
Conclusion
The story of India’s DPI success is not just about technological advancement but also about reimagining governance, economic systems, and social inclusion. India’s experience shows that DPI is necessary for countries aiming to enhance state capacity, empower individuals, and drive economic transformation. The success of Aadhaar, UPI, and the broader India Stack has been made possible by political will, institutional innovation, and a sustained commitment to building digital solutions that are inclusive, accessible, and continuously improving. This was reflected in strong legal frameworks, nationwide deployment strategies, strategic public-private collaboration, and an iterative approach.
India’s DPI model presents a strategic choice for developing nations: wait for legacy institutions to incrementally reform or proactively design technology-first, citizen-centric systems that accelerate progress. DPI has the potential to transform how societies function, making governance more agile, accountable, and people-driven. As the global demand for equitable and accessible digital systems grows, the Indian model highlights the need for governments to invest in open, scalable, and interoperable infrastructure, ensuring that digital transformation benefits everyone.
