In today's time, Aadhaar Card is one of the essential documents for every official work. From opening a bank account to filing an Income tax return, Aadhaar Card is a must for all.
If it is lost or misplaced, then you may land in trouble. Hence, it is essential to keep it safe and secure. The 12-digit unique number, which is being provided by the Unique Identification Authority of India (UIDAI), also serves as valid proof and is an essential document for availing government subsidies.
