Changes to the credit transfer related to ISO 20022
On 15 November 2025, we changed the credit transfer, split payment and internal FX transfer forms.
We implemented the structured counterparty address by adding new address fields:
street,
building no.,
suite no.,
postal code,
city,
country.
Reason for the changes
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 2026, 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 transfers in the new XML (ISO 20022) PAIN.001.001.09 version. We will upload information about the new structure at: ISO 20022 – changes in payment formats
Schedule of the changes
We encourage you to implement relevant changes in your ERP systems and to send transfers using the new version of the counterparty address as quickly as possible.
At the same time, we would like to remind you that in November 2026 we will remove the option to order transfers with an unstructured counterparty address within settlements in the SORBNET system as well as in foreign payments, SEPA and EuroExpress transfers.
