This means that whether you want to receive a salary/credit transfer or setup a direct debit, within SEPA your IBAN must be accepted.
If you’re faced with the problem related to the acceptance of your IBAN, e.g. your employer is only accepting an IBAN specific to the country where you reside, we would recommend the following options:
Inform your employer (or other party) that your IBAN must be accepted as per EU law
Contact your relevant national authority and provide directly to them all info that you have about this (your contact details, company or merchant name refusing acceptance of your IBAN)
