Swift offers a free address-structuring tool ahead of the 2026 deadline
To help institutions meet the structured-address requirement, Swift has made an address-structuring model available as a free, open-source tool that converts free-text postal addresses into the structured or hybrid ISO 20022 format, so the roughly two-thirds of messages still carrying unstructured addresses can be cleaned up before enforcement.
ARCHIVED 14 JUL 2026 The tool has been available for over eight months; readiness guidance now lives under the mandatory structured/hybrid address item rather than standing alone as a separate development.
Meeting the structured-address requirement means turning free-text names and addresses held in core systems into the tagged elements ISO 20022 expects — town name, country, building number and the rest. That data cleansing is the slow part of the 2026 deadline for many institutions, because address data was captured over decades in inconsistent formats.
To help, Swift released an address-structuring model as a free, open-source tool that parses unstructured address lines into structured or hybrid form. It is one input to a firm's own data-quality work rather than a complete answer: results still need checking, edge cases still need human judgement, and the accountable record stays with each institution. The tool was published ahead of the November 2026 enforcement date so firms had time to test and adopt it as part of their migration.
