Mumbai: The RBI asked banks to comply with the one-address-proof norm as it was found that many of them were not following the new rules. Despite its clear instructions on requirement of one proof of address, whether permanent or current, RBI said it was brought to its notice that some banks were still insisting on submission of a proof of current address even when a customer produced a proof of permanent address. Banks are advised to ensure that customers are not unnecessarily asked to submit additional proofs of addresses for current addresses in cases where proofs of addresses for permanent addresses are already available.
