KYC - "Know Your Customer" is a one time process. It is governed by CVDL. For KYC, you will need to fill up a simple form. You will have to to submit self attested photo copies of your PAN Card and your address proof such as Ration Card, Latest Bank Statement, Driving License, etc. The address you fill in the form should exactly match in the address proof that you carry. You should also carry your original PAN Card and Address proof along with the filled in application form to the nearest CVDL Center. The originals will be verified over the desk and given back to you.
You will receive an acknowledgement for your KYC immediately across the counter. You must attach a photocopy of that KYC Acknowledgement along with all your investments in Mutual Funds.
