KYC identifier requirement: Aadhaar and PAN/Form 60 must be submitted by a notified date; noncompliant existing accounts suspended. Amendment requires clients to submit Aadhaar and either Permanent Account Number or Form No. 60 by a date to be notified by the Central Government, replacing a fixed deadline. Existing account relationships that fail to submit Aadhaar and PAN by the notified date will cease to be operational until the identifiers are provided.
