Alena With the usual one I can only indicate an IBAN which seems like not enough
Hey Alena, it's not totally clear to me what you're trying to ask. If you have received an invoice from for example a utility company, you can pay it just by clicking on the Pay button and filling in amount, IBAN and name. No further information is needed inside the SEPA to send bank payments. The IBAN is an internationally unique string that identifies a certain bank account and includes all information about country, bank name, bank branch, account number inside.
If I have misinterpreted your question then please come again :)
