Do I need an IBAN for every bank transfer?

No.

Key points

• The data type depends on the transfer channel; for example, InstaPay supports more than one ID, while other transfers may require an IBAN.

• If the entity requests an IBAN, use it exactly as issued by the bank and don't manually deduce an account number from it.

The figures, fees and limits in this answer vary by bank and change over time — confirm them with your bank or the official source before acting.
