FF01

Invalid File Format

Un errore strutturale o di formato nel messaggio di pagamento ha impedito alla banca ricevente di elaborarlo.

FF01 is a technical rejection. The payment message itself is structurally wrong — a mandatory field is missing, a date is in the wrong format, an IBAN fails check-digit validation, or a BIC has the wrong number of characters.

This is the sender's bank's error, not yours. Contact your bank, quote the UETR and the FF01 code, and ask them to correct and resend the message.

How to fix FF01

Contattare la propria banca (mittente), comunicare UETR e codice FF01 e richiedere la correzione.
