Aadhaar is India's official digital identity system, issued and managed by the Unique Identification Authority of India (UIDAI). It provides every resident with a unique 12-digit number that serves as a trusted identity proof across banking, government services, telecom, education, healthcare, and more.
In 2025, UIDAI has streamlined Aadhaar services through the MyAadhaar portal, allowing users to complete most tasks online such as Aadhaar registration appointments, OTP verification, e-Aadhaar download, Virtual ID (VID) generation, status tracking, and detail updates securely and conveniently via uidai login.
This complete Aadhaar user guide explains every major Aadhaar service step by step in a simple, accurate, and user-friendly manner.
