Based on a 20 December 2011 memorandum, the EU parliament resolved the mandatory dates for the adoption of the IBAN on 14 February 2012. On 1 February 2014, all national systems for credit transfer and direct debit were abolished and replaced by an IBAN-based system. This was then extended to all cross-border SEPA transactions on 1 February 2016 (Article 5 Section 7). After these dates the IBAN is sufficient to identify an account for home and foreign financial transactions in SEPA countries and banks are no longer permitted to require that the customer supply the BIC for the beneficiary's bank.
