The Unique Identification Authority of India (UIDAI) is the statutory agency responsible for issuing and managing Aadhaar, India’s 12-digit unique identity number that links demographic and biometric data of residents. UIDAI operates under the Ministry of Electronics & Information Technology. The official portal uidai.gov.in is the central hub for Aadhaar enrolment, updates, verification services, regulations, and announcements.
