Dear Sir,
Usually Bankss accept rent agreement between tenant and owner.

Some nationalized banks request for some other address proofs and not just rent agreement. For the such woes Indian Postal Department has come up with facility of Address proof.
You need to purchase a form for Address proof from your nearest post-office, attach your identity (passport/pan card etc) and mention your current address where you are putting up & submit with post master. Postal Dept official will visit your place to verify and issue you an address proof. The whole procedure takes 30 days to get valid and certified address proof. Based on this you can open bank account.

Hope this helps.
