Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI) to residents of India, based on their biometric and demographic data.
Any individual, including infants, residing in India is eligible to apply for an Aadhaar number, regardless of age or gender, by providing necessary identity and address proofs.
Typically, proof of identity (e.g., PAN card, passport) and proof of address (e.g., electricity bill, bank statement) are required. A list of acceptable documents is available on the UIDAI website.
While Aadhaar is widely used and mandatory for several government subsidies, welfare schemes, and tax-related services, the Supreme Court has clarified its limited mandatory scope for certain private services.
You can update demographic details online via the UIDAI portal, or both demographic and biometric data by visiting an Aadhaar Enrolment/Update Centre with supporting documents.
