SWIFT: New Requirements for International Payments in 2026
In 2026, the international payment system SWIFT is continuing its transition to the new ISO 20022 standard for financial messaging. A key component of this reform involves updating the requirements for address data in international transactions. While these new rules were initially scheduled to take effect on November 14, 2026, SWIFT announced in August that the transition period would be extended due to a lack of technical readiness among market participants. Despite this delay, the overall direction of the reform remains unchanged: international payments must now be accompanied by more detailed and structured information.
What the SWIFT reform entails
The primary objective of this update is to move away from the use of entirely unstructured postal addresses in payment messages. Previously, banks could transmit information about the sender and recipient as a single, continuous string of text. The new ISO 20022 standard requires this information to be broken down into distinct, dedicated fields.
Specifically, address data must include:
- the town or city name;
- the country code;
- the street, building number, and postal code (where applicable);
- other details necessary to identify the parties involved in the transaction.
Two formats are permitted: fully structured and hybrid. In the hybrid format, core details—such as the city and country—are placed in separate fields, while additional information may still be provided as a text string.
Why the implementation was postponed
SWIFT had originally planned to phase out unstructured addresses starting November 14, 2026. However, many banks, payment institutions, and national infrastructures were unable to complete the necessary technical adjustments in time.
On August 27, 2026, SWIFT announced an extension of the transition period. The organization decided to defer the "Standards Release 2026" payment updates and will conduct further consultations with banks, central banks, and other participants in the payment market. The updated timeline and implementation procedures for these requirements are to be announced no later than December 2026.
However, this postponement does not mean the reform has been cancelled. Banks and corporate clients are advised to continue their preparations for the transition to structured address data.
How the new rules will affect international companies
These changes will impact organizations that regularly send or receive international transfers. Companies will need to verify information regarding their foreign counterparties and ensure that their payment systems are capable of transmitting address data in the required format.
Particular attention should be paid to corporate payment templates, ERP systems, and financial management software. Once the new requirements come into effect, if the necessary information is missing or incorrect, banks may request additional details, delay processing, or reject individual payments.
What banks need to do
Financial institutions will need to adapt their software, update client verification procedures, and ensure that their internal systems are compatible with the ISO 20022 standard. They will also need to inform their corporate clients about the new rules for completing payment orders.
Higher-quality data will enable the automation of payment processing, improve the efficiency of sanctions screening, and reduce errors in the identification of senders and recipients.
