India’s Aadhaar infrastructure is preparing for a major scale-up, with the Unique Identification Authority of India (UIDAI) planning to handle 25–30 crore authentication transactions a day, up from around 10 crore currently.
UIDAI chairperson Neelkanth Mishra made the announcement at the Global Fintech Festival 2026 in Mumbai, highlighting the rapid expansion in the use of Aadhaar as a digital identity and trust layer.
More than 600 entities now use Aadhaar, according to Mishra. The platform is increasingly being integrated into financial services and other digital processes that traditionally relied on physical documents and face-to-face verification.
Aadhaar’s authentication infrastructure was originally designed to handle up to 100 million authentications a day. UIDAI’s current plan would take that capacity to as much as three times the original level.
The scale of Aadhaar usage is already substantial. UIDAI’s official dashboard shows 17,759.21 crore authentication transactions across sectors during FY 2025-26, involving 492 authentication user agencies and 35 authentication service agencies.
The sharp increase in daily usage reflects the growing shift towards remote identity verification and paperless services.
Mishra said the pace of growth had exceeded expectations and that UIDAI was strengthening its infrastructure to accommodate the next phase of expansion.
The expansion is not limited to institutional authentication.
The Aadhaar app, which allows residents to access and update several Aadhaar-related services digitally, has crossed nearly 60 million downloads, up from about 50 million only a few weeks earlier.
The app currently supports services including mobile number and address updates, biometric lock and unlock, selective sharing of Aadhaar credentials, checking authentication history and downloading e-Aadhaar.
This marks a gradual shift from Aadhaar being primarily a government-issued identity number to becoming a more active digital identity platform that individuals can manage through their smartphones.
UIDAI has also introduced a new Face Authentication Software Development Kit aimed at making Aadhaar authentication easier for banks and other partner institutions.
The new technology can allow partner organisations to conduct Aadhaar face authentication locally on their own servers instead of routing every request through UIDAI’s central systems. It is also intended to address geofencing-related restrictions affecting Indians travelling or living abroad.
The move could be important as Aadhaar-based services expand beyond traditional government applications into banking, fintech and other digital services.
Greater scale also brings greater security challenges. UIDAI is using artificial intelligence to strengthen fraud detection as Aadhaar-based services become more widespread. The authority is also working on a technology roadmap that includes post-quantum cryptography, aimed at protecting the system against future advances in computing that could undermine existing encryption technologies.
UIDAI says its authentication infrastructure operates through multiple data centres in an active-active configuration to maintain high availability, while its central identity repository can be scaled as demand rises.
The larger ambition is to make Aadhaar an almost invisible part of India’s digital infrastructure.
Instead of users repeatedly submitting documents or proving their identity through physical processes, Aadhaar could increasingly work in the background to establish identity and trust when authorised by the user.
Mishra has also pointed to the potential use of Aadhaar in emerging agentic technologies, where AI agents could eventually perform tasks on behalf of users, including authentication and identity-sharing.
The government’s broader digital public infrastructure strategy is already positioning Aadhaar alongside UPI and consent-based data-sharing systems as a foundation for large-scale digital services. The Global Fintech Festival 2026 has placed particular emphasis on taking these systems into the next phase of innovation.
The planned jump to 25–30 crore daily authentications therefore represents more than a technology upgrade. It signals the next stage in Aadhaar’s evolution — from a massive identity database into a high-volume digital trust infrastructure supporting an increasingly connected Indian economy.
