The Aadhaar Card has become one of the most essential identity documents in India, used for everything from bank verification to accessing government services and digital platforms. In 2025, the importance of keeping your Aadhaar details accurate and updated is greater than ever, as more services rely on it for seamless authentication.
This blog provides a complete and easy-to-understand guide on everything related to the Aadhaar Card including how to update your details, download your Aadhaar in different formats, correct errors, check status, order PVC cards, and fix common issues.
What is an Aadhaar Card?The Aadhaar Card is a unique identification document issued by the Unique Identification Authority of India (UIDAI). It contains a 12-digit unique Aadhaar number that serves as proof of identity and address for Indian residents. Aadhaar captures both demographic details like name, address, date of birth and biometric data such as fingerprints and iris scans, making it one of the most reliable ID systems in the country.
Aadhaar functions using a highly secure central database managed by UIDAI. When an individual enrolls for Aadhaar, their biometric and demographic information is encrypted and stored in UIDAI’s Central Identity Data Repository (CIDR).
Whenever Aadhaar is used for verification (KYC, bank accounts, SIM activation, etc.), the database instantly confirms the identity through biometric or OTP authentication, ensuring accuracy and preventing duplicate or fake identities.
In 2025, Aadhaar plays a crucial role in almost every identity-related process. It is widely used for:
