Issued by the Unique Identification Authority of India (UIDAI), the
Aadhaar card is one of the most important of all documents that serve as proof
of identity for an Indian citizen/resident. The Aadhaar contains a unique 12-digit number for identification along with the photograph, personal details,
biometric information, and the demographic details of the Aadhaar holder. This
means your Aadhaar must be free from errors and the information stored needs to
be updated whenever there is a requirement.
