Aadhaar is a 12-digit unique identification number issued to Indian residents by the Unique Identification Authority of India (UIDAI) , a statutory authority constituted under the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016, commonly called the Aadhaar Act, 2016. Aadhaar is the world’s largest biometric identity system: as of 2026, over 1.4 billion Aadhaar numbers have been issued (more than 99 per cent of the eligible Indian resident population), with the enrolment infrastructure operated through enrolment agencies and Common Service Centres across India. The Aadhaar ecosystem includes the Aadhaar e-KYC API, the Aadhaar-based e-sign framework, Aadhaar Authentication services, and AAdhaar offline-XML pathway, which together form the operational backbone for digital identity verification across Indian financial services, government welfare delivery, telecom, and other regulated sectors.
