The government has made Aadhaar mandatory for investment in all small savings schemes including Post Office Deposits, Public Provident Fund, the National Savings Certificate scheme and Kisan Vikas Patra. Existing investors in these schemes will have to provide the 12-digit unique identification number by December 31.
Those who do not have Aadhaar will have to provide details of their request for enrolment.
Aadhaar is already mandatory for bank accounts, mobile connection and availing direct benefit transfers.
The government is using Aadhar to weed out bogus beneficiaries and track down black money.
The rule will apply to savings accounts, recurring deposits, time deposits, monthly income scheme, Sukanya Samriddhi Account, Senior Citizens Saving Account. The government had last month extended the date for providing Aadhaar for a number of schemes, services and benefits by December 31 from September 30. The Aadhaar will allow the government to link multiple accounts and thereby trace money.
