Hi,

You can take your ration card as an id proof if you have lost your adhaar card. To help you out let me tell you that even if you loose your adhaar card you can still download it online by providing your phone number and UID No. and you can get a digital copy of your adhaar card.

The official website to download adhaar card and other related queries you can use following link:
