Digital Public Infrastructure (DPI)
India Stack Model
Digital Public Infrastructure refers to shared digital systems — built on open standards and protocols — that provide essential services to an entire population. India's DPI approach, branded as "India Stack," has become a global model, with the framework endorsed at the G20 New Delhi Leaders' Declaration (September 2023).
- Identity layer: Aadhaar (12-digit unique identity) — over 139 crore registrations, enabling authentication for government services and financial transactions.
- Payments layer: Unified Payments Interface (UPI) — processes over 14 billion transactions monthly (2025 data), enabling real-time person-to-person and person-to-merchant payments.
- Documents layer: DigiLocker — digital document verification and storage, linked to Aadhaar.
- Data Governance: India's DPI model emphasizes data empowerment and protection through the Digital Personal Data Protection Act, 2023 (DPDP Act).
- G20 New Delhi Leaders' Declaration (2023) explicitly endorsed DPI as "shared digital systems... to enable service delivery to its population," recognizing India's leadership in this domain.
- AgriStack extends the DPI approach to agriculture, creating domain-specific registries that plug into the broader India Stack ecosystem.
