ECB-PUBLIC Questions and Answers Question : When to use structured address for debtor and creditor? Answer: The introduction of structured address information for debtor and creditor in payment messages is a key business benefit of the migration to ISO 20022 and follows a staggered approach due to the need of interoperability during the co-existence phase of ISO 20022 MX and FIN MT messages between November 2022 and November 2025: In general, if address must be used, it is recommended to use structured address only As of November 2022:
Effective with the start of the MX-MT co-existence phase it is expected to use a structured address of the debtor and creditor, if a payment is initiated by the debtor’s agent in ISO 20022 which will be the case for T2 participants As of November 2023: Also, for payments initiated on FIN or by a market infrastructure not on ISO 20022 yet, the same strong recommendation to use a structured address of the debtor and creditor applies As of November 2025: The unstructured “address line” element will be removed in payment messages 25 www.ecb.europa.eu ©
