Since you already have a Demat A/c, you do not have to resubmit your documents. You should probably be KRA registered. KRA is KYC (Know Your Client) Registration Agency. You have to let us know PAN so that we can check. If you are KRA registered we can accept your KRA registration to the open your trading+Demat account with Swastika. If your current details match, we won’t require your identity and address proof.
