Your company`s account details will remain unchanged. Your account details will be projected in the international standardised form IBAN instead of BBAN.
The bank currently displays your account details in the IBAN form in the account statement of the A4 format or the SEPA XML. The IBAN form of your account details is also listed in the Internatbanking.
You can use the IBAN calculator to ascertain your IBAN number.
