Aadhaar Card Download refers to the process of obtaining a digital copy of your Aadhaar card, a unique identification document issued by the Government of India. This can be done through the official UIDAI (Unique Identification Authority of India) website. The e-Aadhaar, as it's known, is a digitally signed and equally valid version of the physical card. To download it, individuals need their Aadhaar number, enrollment ID, or virtual ID, along with a registered mobile number to receive a one-time password (OTP). The e-Aadhaar can be used for various identification purposes and is a convenient way to access your Aadhaar details anytime.
