Update Aadhaar Card Online via Mobile

The Unique Identification Authority of India (UIDAI) operates under the Planning Commission of India to manage Aadhaar, a 12-digit unique identity code containing a combination of numbers and alphabets, assigned to individuals by the UIDAI. Aadhaar collects and stores biometric and demographic data of individuals in a centralized database. The e-Aadhaar is an electronic form of the Aadhaar card that can be downloaded online by providing an individual’s Aadhaar or enrollment ID. As India advances its digitalization mission, organizing citizens' data under a centralized database is crucial.
