<P> Banks in numerous non-European countries including most states of the Middle East, North Africa and the Caribbean have implemented the IBAN format for account identification . In some countries the IBAN is used on an ad hoc basis, an example being Ukraine where account numbers used for international transfers of four of the national banks have additional aliases that follow the IBAN format as a precursor to formal SWIFT registration . </P> <P> The degree to which bank verifies the validity of a recipient's bank account number depends of the configuration of the transmitting bank's software--many major software packages supply bank account validation as a standard function . Some banks outside Europe may not recognize IBAN, though this is expected to diminish with time . Non-European banks usually accept IBANs for accounts in Europe, although they might not treat IBANs differently from other foreign bank account numbers . In particular, they might not check the IBAN's validity prior to sending the transfer . </P> <P> Banks in the United States do not use IBAN as account numbers for U.S. accounts . Any adoption of the IBAN standard by U.S. banks would likely be initiated by ANSI ASC X9, the U.S. financial services standards development organization: a working group (WGAB20) was established as an X9 subcommittee to generate an IBAN construction for U.S. bank accounts . </P> <P> Canadian financial institutions have not adopted IBAN and use bank transit numbers issued by the Canadian Payments Association for domestic transfers, and SWIFT for international transfers . There is no formal governmental or private sector regulatory requirement in Canada for the major banks to use IBAN . </P>
