SWIFT's November 2026 CBPR+ milestone will formally decommission fully unstructured postal addresses in payment messages and discontinue the interbank MT101 Request-for-Transfer format, replacing it with pain.001 (v9).
Key Changes
Unstructured addresses removed: Payment messages must now include structured address data - at minimum Town Name and Country Code in dedicated ISO 20022 fields. Free-text address blocks that cannot be parsed will be rejected.
MT101 discontinued: The legacy MT101 Request-for-Transfer message is being replaced by pain.001 version 9. Financial institutions still using MT101 for interbank request-for-transfer flows must migrate to the ISO 20022 equivalent.
Charges for Non-Compliance
Financial institutions still relying on contingency processing or in-flow translation face additional charges introduced in January 2026. SWIFT is using pricing signals to accelerate adoption - institutions that cannot send or receive native MX messages pay a premium for translation services.
Structured Address Requirements
The structured address mandate requires: Town Name in the dedicated field (not embedded in a free-text line) Country Code (ISO 3166-1 alpha-2) in the dedicated field Street name and building number recommended but not yet mandatory Post code recommended but not yet mandatory
What This Means
This milestone marks the end of the "soft" coexistence approach. Institutions that have not invested in ISO 20022 readiness will face both operational and financial penalties. The November 2026 deadline is the most consequential CBPR+ milestone since the initial MX launch in November 2022.
