The validity of ‘white’ and ‘yellow’ family cards that could be used only as a proof of identity and residential address could be renewed online by logging into http://www.consumer.tn.gov.in/, clicking the ‘N Cards Renewal for 2015’ link, on the homepage. On entering the PDS card number, the card holders can take a printout of an online acknowledgement of the renewal and paste it in the ration card.
