Focus Layer: L3 Documents & Data Exchange
Coverage Period: March 4-11, 2026

Executive Summary

India’s L3 layer—the Documents & Data Exchange infrastructure—has reached unprecedented scale milestones this week. DigiLocker has surged to 67.63 crore users with over 950 crore documents issued, while API Setu now hosts over 8,000 APIs enabling seamless government-private sector integration. The convergence of DigiLocker, eSign, and API Setu is creating a paperless governance ecosystem that processed billions of transactions this week, reinforcing India’s position as a global leader in digital public infrastructure.

Key Developments

1. DigiLocker Crosses 950 Crore Documents Milestone

India’s flagship digital document wallet, DigiLocker, has achieved a historic milestone. As of March 2026, the platform has issued over 950 crore (9.5 billion) documents to its growing user base. 1

The platform, launched in 2015 under the Digital India initiative, provides citizens with a secure digital document wallet to store, access, and share authenticated electronic documents with consent-based access. The system ensures document authenticity and significantly reduces the use of forged credentials.

Key statistics (as of March 5, 2026):

  • 67.63 crore (676.3 million) registered users
  • 950+ crore documents issued
  • Integration with multiple government agencies for real-time document issuance

The platform has become integral to various sectors including banking, education, healthcare, and transportation. Citizens can retrieve critical lifelong records—including driving licenses, vehicle registration certificates, academic mark sheets, and governmentissued certificates—anytime and from anywhere.

DigiLocker’s architecture allows issuing authorities to push documents directly to users’ lockers, creating a verifiable digital trail while eliminating the need for physical document handling. This has been particularly transformative for service delivery in remote and rural areas.

2. API Setu Expands to 8,036 APIs

The Open API Platform, popularly known as API Setu, has expanded its repertoire to 8,036 APIs as of March 2026. 2 Initiated by MeitY in March 2020, API Setu serves as the backbone for secure data exchange between government systems and private sector applications.

API Setu enables:

  • Real-time verification of organizational details for GST registration
  • Streamlined credential verification for educational documents via eSanad
  • Seamless government-to-citizen services
  • Private sector integration with core identity infrastructure

The platform has become crucial for fintech companies, banks, and insurance providers who rely on government data verification APIs for KYC (Know Your Customer) processes. By providing standardized, secure interfaces, API Setu has dramatically reduced the time and cost associated with verifying customer credentials.

The sandbox environment at sandbox.api-setu.in allows developers to test integrations before deploying to production, facilitating rapid innovation while maintaining security standards.

3. Aadhaar eSign Powers Digital Contract Revolution

Aadhaar eSign, India’s legally binding electronic signature solution, continues to transform digital contract execution across sectors. 3 Built on NSDL and eMudra infrastructure, the service enables users to digitally sign documents using Aadhaar authentication.

Capabilities:

  • Supports up to six signers per document
  • Legally enforceable electronic signatures under the Information Technology Act
  • OTP-based authentication via Aadhaar-linked mobile numbers
  • Integration with DigiLocker for seamless document signing

Financial institutions have been early adopters, using eSign for:

  • Loan disbursement agreements
  • Insurance policy contracts
  • Account opening documentation
  • Wealth management services

The eSign workflow involves uploading a PDF document, creating a signature request with specified signers, authentication via OTP, and downloading the signed document—all completed within minutes.

4. UMANG Records 723 Crore Transactions

The Unified Mobile Application for New-age Governance (UMANG) has recorded 723.36 crore transactions as of March 5, 2026, with over 10.25 crore user registrations. 4

UMANG serves as a single-window mobile and web platform accessing services from central, state, and local government bodies. The platform offers more than 2,400 government services, including:

  • EPFO balance and claims
  • PAN and Aadhaar services
  • DigiLocker access
  • Utility bill payments
  • Pension services
  • Scholarship applications
  • Passport services
  • Driving licence services
  • Exam results

The integration of DigiLocker within UMANG has been particularly significant, enabling citizens to access their digital document repositories directly through the mobile app. This convergence represents the L3 layer’s power to create unified citizen experiences.

5. eSanjeevani Serves 45 Crore Patients

India’s telemedicine platform eSanjeevani, which handles digital health records and consultations, has served 45.42 crore patients and onboarded 2.3 lakh healthcare providers as of March 5, 2026. 5

The platform demonstrates how the L3 layer extends beyond document storage to enable:

  • Remote doctor-patient consultations in rural and underserved regions
  • Digital prescriptions and medical records
  • Integration with Ayushman Bharat Health Account (ABHA)
  • Cross-platform interoperability for health data exchange

eSanjeevani’s success illustrates how document and data exchange infrastructure can be adapted for sector-specific applications, creating specialized layers within the broader DPI ecosystem.
