The deadline to link Aadhaar with various financial services like bank accounts, mutual funds, insurance, mobile phone connections as well as your permanent account number has been indefinitely extended by the Supreme Court recently. But there are still some places where you will need to submit Aadhaar, like when opening a new bank account or getting a subsidy.
While the deadlines have been extended, fraudsters are trying to take advantage of the earlier deadline of 31 March to call individuals and extract data from them, which can further be used to commit fraud. If you get a call asking for any bank-related details, do not disclose anything.
