The UIDAI says restrictions are in place to ensure Aadhaar number and bank account details are not published. FACT: According to UIDAI, the Aadhaar Act provides that no agency will be able to track an individual through Aadhaar. If the beneficiary does not have an Aadhaar number, he or she is required to enrol for one. FACT: Aadhaar number, bank account number and mobile numbers are not secret but sensitive personal identity information. That said, you should try and not share your bank account numbers, your Aadhaar number on a social media platform.
