Many working people often shift their houses. For them, it is difficult to produce an address proof issued by Govt with latest address. 
Our India post (post office) has come up with a solution. 
Now you can get an Address proof along with your photo from India post. 
  
Since the ID proof is issued by India post which is a central government organization, it is similar to Govt ID cards like Driving license, Voters ID etc. 
  
It can be used for opening bank accounts, for getting telephone/internet connections etc. 
The total cost for getting this ID card is Rs.250/ (Rs.10 for application and Rs.240/- processing fee). 
Inform everybody. This is very useful
