Swift grants reprieve on ISO 20022 structured address mandate after banks flag readiness gaps #

Swift has pushed back its November 2026 deadline requiring financial institutions to drop free-text postal addresses in ISO 20022 payment messages, after a significant portion of the banking community formally requested more time, citing compliance shortfalls.

The messaging cooperative said it will apply a controlled extension to Standards Release 2026 (SR2026), deferring all planned payments-related changes. The original mandate, agreed upon by the community in 2023, would have eliminated unstructured postal address fields from cross-border CBPR+ payment messages by 14 November 2026. From that date, only fully structured or hybrid postal addresses were to be accepted, requiring at minimum a structured town name and country code, with non-compliant messages rejected outright.

Swift’s own data showed that as of April, 61.2% of payments on the network still carried unstructured debtor postal addresses and 62.9% contained unstructured creditor information, meaning a majority of traffic would have been at risk of rejection under the original schedule.

Several banking communities formally petitioned Swift to revise the timeline. Swift said it will spend the coming weeks consulting banks, central banks, payment market infrastructures, market practice groups, and corporate clients to determine a new deadline and implementation approach. A formal update is expected by December, in line with Swift’s governance cycle.

Not all SR2026 changes will be delayed. Swift is separating the payments-specific requirements from other components of the release, including changes supporting T+1 settlement in certain markets, which will proceed on a faster track and go live in the first quarter of 2027.

The structured-address requirement is part of Swift’s broader ISO 20022 migration, which is replacing legacy free-format messaging with machine-readable data. Supporters say structured addresses improve straight-through processing, compliance screening, and payment automation. Banks that have already completed the upgrade are capturing those benefits, Swift noted, and it called on remaining institutions to accelerate work during the additional time.

The delay follows earlier phased extensions during the MT-to-MX coexistence period and may draw scrutiny from institutions that have already invested in on-time remediation.
