How to check if your Aadhaar card number was misused?

Aadhaar is the 12-digit number issued to the Indian citizens by Unique Identification Authority Of India (UIDAI). It contains both the demographic as well as biometric data of the citizens. It is used as a digital identity proof for availing a host of government subsidies and benefits. In some cases, such as for getting a permanent account number (PAN) card by the Income Tax Department or getting food essentials under the public distribution system (PDS), having an Aadhaar is mandatory.

However, due to a number of reports over the past couple of years regarding the security of Aadhaar database, it is quite natural for citizens to be worried about the use of their data. We explain how you can check where all your Aadhaar has been used.
