Ration card for Schengen VISA application

From the question, it looks like you were asked a ration card for a civil status proof, and not as an address proof. However, the answers aim at the address proof.

In most cases, even for the Schengen visa when I applied for one, the passport works as both civil status and address proofs. However, if your passport also has a different address than your current once then you could use a BSNL phone bull or an electricity bill for address proofs. I am not sure if the Aadhar card and the voter's ID card work well as address proofs but they'd certainly be sufficient for the civil status proof. A PAN card is another document that works perfectly fine as a civil status proof.
