India's Digital Public Infrastructure (DPI) — the 'India Stack' — is being adopted and piloted by dozens of countries worldwide.
India has signed DPI cooperation agreements with about 24 countries, and around 25 nations are running pilots of components of the stack.
Widely adopted platforms include Aadhaar, UPI, DigiLocker, CoWIN and GeM.
UPI is now live in several countries, including the UAE, Singapore, France, Mauritius and Sri Lanka.
India promotes DPI globally through initiatives such as India Stack Global and the Global DPI Repository.
DPI refers to shared, open digital systems — for identity, payments and data exchange — that both government and private players can build on, much like public roads or electricity grids. India's 'India Stack' combines digital identity (Aadhaar), real-time payments (UPI) and data-sharing (DigiLocker) as a model for inclusive digital services.
Simple Analogy: DPI is like public roads for the digital economy — the government lays the roads (identity, payments, data), and anyone can drive their own services on top.
