ISO 20022: Address Information in Payment Files to Change in November 2026 – Is Your Organization Ready?
A significant change is coming to the application of the ISO 20022 payment messaging standard in November 2026. Moving forward, the use of free-form addresses will be discontinued, and address information must be transmitted in a structured format. This change affects all organizations that generate payment files from their source systems, whether they are ERP systems, payroll software, or other financial management applications.
What is Changing?
Until now, it has been possible to report the beneficiary's address in payment files using free-form address lines (unstructured addresses), where all parts of the address are bundled into one or two text fields. This method will be phased out in November 2026.
From November 2026 onwards, standalone free-form address lines will no longer be accepted. Instead, address information must be transmitted in either a structured or hybrid format. This change is based on the tightening requirements of SWIFT and global payment systems. In practice, this means that different parts of the beneficiary's address (e.g., street address, city, postal code, country) must be stored and transmitted in their own separate fields within the payment file.
Which Address Formats are Allowed?
The ISO 20022 standard recognizes three address formats, of which the unstructured format is being discontinued:
- Structured Address (Recommended): All parts of the address are reported in their own structured fields. The "Address Line" element is not used at all. Mandatory fields are City (Town Name) and Country. Additionally, specific elements for street name, building number, and postal code can be used.
- Hybrid Address: Combines structured and free-form elements. City and Country are mandatory in their structured fields, in addition to which up to two free-form address lines (max. 70 characters each) are permitted for supplementary information. Structured data must not be repeated on the free-form lines.
- Unstructured Address – Discontinued in November 2026: Payment files containing only free-form addresses may be rejected by banks starting from November 2026.
Why is the Change Being Implemented?
The change is driven by the transition of banking infrastructures to ISO 20022 messaging. Structured address data is a requirement set by SWIFT and payment systems to enable compliant screening of parties to prevent money laundering and financial crimes. At the same time, structured addresses reduce manual errors and enable more reliable delivery of payments to the recipient.
Who is Affected?
The change affects all organizations and systems that generate payment files. It impacts both international payments and SEPA payments.
In practice, every organization with a system that handles payments (ERP, payroll, travel and expense management) must ensure that address information is transmitted according to the new standard.
What Should You Do Now?
Structuring address information often requires changes to both data content and system integrations. We recommend proceeding in stages. Begin your preparation with a current state assessment to identify which systems generate payment files and how address data is currently organized within them. Once the data sources are identified, the next step is a thorough audit and cleansing of the data. During this—often the most labor-intensive phase—incomplete address details must be corrected and the information separated into the required structured fields.
Following the data cleanup, you must ensure the technical readiness of your systems and, if necessary, update the processes for collecting vendor information to comply with the new standard. Finally, it is crucial to test your payment files well in advance with actual test payments and verify that they meet bank-specific implementation guidelines before the deadline.
Summary
The November 2026 deadline is approaching, and the effects of this change extend to an organization's IT systems and processes. Preparation should begin now to ensure your company's payment traffic continues without disruption after the transition.
