General Questions on the ISO 20022 impact for MultiLine users
Important Update: Structured Address Requirements Timeline Changes
Following requests from several market participants and ongoing discussions across the global payments’ community, Opens in a new tabSWIFT announced on 27 August 2026 that the implementation of the Swift Release 2026, planned for November 2026 and which includes structured address requirements, has been postponed. Industry discussions had highlighted concerns about market readiness and interoperability, particularly regarding the mandatory retirement of fully unstructured postal addresses. No new deadline has been communicated yet, we will closely monitor and inform you accordingly.
ING’s recommendation remains unchanged
Although the general compliance deadline has been extended by Swift, not all market infrastructures (clearing systems for other payment currencies) have done so at this time. ING therefore encourages clients to continue their migration activities as planned. We will communicate updates as received from the different market infrastructures.
Moving to structured and hybrid address formats remains an important part of the ISO 20022 and CBPR+ transformation programme. Early adoption will reduce payment repair activities, improve straight-through processing, and prepare your organisation for future market requirements. Industry stakeholders, including ING, continue to regard structured data as the long-term standard for payments and direct debits.
What is changing?
- As of the 15th of November 2026, Multiline will not allow MT101 payment upload anymore.
- In line with the new SWIFT release, whenever a counterparty address is required, it must include at least the town/city name and Opens in a new tabISO-2 country code in Opens in a new tabstructured address elements. Payments that do not meet these minimum requirements will be rejected.
- Even when a counterparty address is not required, any payment containing an unstructured address will be rejected.
A counterparty address is required for:
- Domestic payments: All non-standard domestic payments, including urgent or high-value payments, must comply with the mandatory address requirements. Standard low-value, non-urgent domestic payments (non-urgent SEPA) are not impacted as they continue to follow local clearing specifications. For instance, Switzerland is an exception where the address is mandatory and must be provided using structured address elements.
- International payments: All international payments must comply with the mandatory address requirements.
- EURO CT Real Time (EUR urgent): SEPA Credit Transfers are not impacted. Please note that EUR Urgent payments are considered high-value payments and the address is therefore mandatory.
- Direct Debits: When debiting to a non-european economic area country, the same address requirements apply.
Why are these changes happening?
The changes result from new SWIFT requirements related to ISO 20022 standard, a messaging standard that creates a common language for payment data across the globe, enabling faster processing and improved reconciliation.
The SWIFT ISO 20022 migration is a global initiative, which aims to achieve harmonized standards for the exchange of high-value and cross-border payment messages. Several Market Infrastructures, such as Target in Europe, have likewise already migrated to ISO 20022, or are on a migration path towards this standard.
What is the impact on batch relay payments?
With the change, Batch/Salary payments (global debit – multiple credits) cannot be processed anymore via your non-ING LU accounts. Manually encoded payments and uploaded files (PAIN1 Relay) containing non-ING LU account(s) will only allow single transactions.
- For your ING Europe accounts (ING LU, as well as other ING country accounts) we will still offer batch file upload via our Inside Business Payments (IBP) platform. Feel free to reach out to your ING contact person to discuss the possibilities.
Will PAIN.001 allow me to send SEPA Instant payments?
Yes, but SEPA instant payments will only be allowed for your ING LU accounts.
- For your ING Europe accounts (ING LU, as well as other ING country accounts) we offer SEPA Instant payments via our Inside Business Payments (IBP) platform. Feel free to reach out to your ING contact person to discuss the possibilities.
What should I do?
Update your payment formats towards the new standards accepted by Multiline.
The ABBL (Association des Banques et Banquiers du Luxembourg) is providing an Opens in a new tabupdated timeline and Opens in a new tabguideline to help professionals & consumers to achieve successfully the ISO 20022 migration.
Regarding the usages of address fields:
- Review your counterparty data for the impacted payment types and ensure that the required structured address elements are available.
- Check whether your payment initiation formats support structured address elements and meet the minimum requirements.
- Update, at least, the town name and ISO-2 country code for your beneficiaries in your address book.
