Mandatory PAN KYC and Nomination compliance may lead to freezing of physical folios until required documents are furnished. SEBI mandates that holders of physical securities furnish PAN, KYC, nomination, contact, bank account details and specimen signature to RTAs; RTAs shall accept self attested documents via IPV, post or e sign, verify PAN through authorised online facilities, update KYC across all folios on holder authorization, freeze folios lacking required details until compliance and restrict payments to electronic mode until documents are furnished, and unfreeze folios upon receipt of all required information.
