On 17 March 2024, we will modify the SEPA transfer form. We will implement the structured counterparty address by adding new address fields:

• street,
• building no.,
• apartment no., 
• postal code,
• city (mandatory),
• country (mandatory).

The changes stem from the introduction of ISO 20022, an international, uniform electronic communication standard for financial systems. Information exchange is based on XML files with a clearly defined data structure. Before we fully transition to the new communication standard, we will give you some time to adapt. Until November 2025, you will be able to use both the structured and the unstructured address (thanks to the option ‘Switch address field’).

To facilitate the transition to the new form, we will make it possible to import SEPA transfers in the new version (XML ISO 20022 pain.001.001.09). We will upload information about the new structure at:
https://www.mbank.pl/msp-korporacje/bankowosc-elektroniczna/pytania-i-odpowiedzi/structure-of-data-transfer-files/

We encourage you to implement relevant changes in you ERP systems and to send transfers using the new version of the counterparty address.
As required by the European Central Bank and the SEPA Scheme, in November 2025 we will remove the unstructured address from the SEPA transfer form.
