Assistant Director-General of the Unique Identification Authority of India (UIDAI) K.K. Sharma has said that LPG consumers who have not seeded their Aadhaar numbers with their LPG consumer number and bank account number will have to do it in six months from September 1. Though the last date for linking Aadhar numbers with LPG consumer numbers is August 31, it can be done later. However, those who have not completed the procedure will have to buy LPG cylinders at the market price from September 1. Once the procedure is done, the subsidy amount would be credited to the bank account of the beneficiaries concerned, he added.
