ISO® 20022 Frequently Asked Questions

ISO 20022 is a global standard for exchanging electronic financial data. It uses XML to provide a common data-rich format supporting all types of financial transactions, including payments, securities, trade, and FX. For Swift, ISO 20022 will fully replace many legacy MT messages for cross-border payment instructions.

• Richer, more structured data: Enables clear, detailed information about payments and parties — improving compliance, automation, and reconciliation.
• Greater transparency: Makes it easier to track payments end-to-end and provides more meaningful remittance information for beneficiaries.
• Efficiency and innovation: Reduces manual intervention, improves analytics, and lays the groundwork for future services.
• Global consistency: One standard used by major global financial markets and banking infrastructures.

All financial institutions sending or receiving Swift cross-border payment instructions (MT 1xx and related messages) via Swift FINplus are impacted. Corporates, technology providers, and market infrastructures handling cross-border payments will also be affected.

The “coexistence period” is when both MT and ISO 20022 messages were accepted for cross-border payment instructions. This period ended on November 22, 2025, after which ISO 20022 became mandatory for relevant Swift traffic.

After coexistence ended, Swift and industry working groups also set a November 2026 milestone when fully unstructured postal addresses will be retired from CBPR+ payment messages, and only structured and hybrid formats will be allowed going forward.

• Provides structured data fields for names, addresses, and remittances, improving screening and reducing errors.
• Enables better end-to-end visibility and automation for all parties in the payment chain.
• Makes compliance processing (AML, KYC, sanctions) faster and more reliable.

• Improved data quality supports straight-through processing and reduces transactional errors.
• Better fraud detection and compliance due to enhanced transparency.
• Enhanced customer experience through richer remittance data, improved payment tracking, and fewer delays.

CBPR+ stands for “Cross-Border Payments and Reporting Plus” — the group of ISO 20022 messages defined by Swift governing institution-to-institution cross-border payments and related reporting.

Primarily, ISO 20022 pain.001 (customer initiation), pacs.008 (customer credit transfer), and pacs.009 (financial institution-to-financial institution payment) will replace relevant MT messages such as MT 103 and MT 202 for payments.

Swift will no longer support MT for payment instructions (CBPR+ scope).

• All applicable cross-border payments sent via Swift must use ISO 20022 messages.
• Non-payment messages and gpi tracking messages may remain MT for now, but new features will only be available under ISO 20022 or APIs.

• Upgrade systems and processes to handle, store, and process ISO 20022 data.
• Implement and test interfaces for Swift FINplus (ISO 20022 message rail).
• Train staff for the new message formats and their operational impact.
• Coordinate with counterparties, vendors, and clients to ensure mutual readiness.

Swift advises that, as of January 1, 2026, there will be new charges for using legacy MT messages via contingency processing and translation services. These charges are meant to encourage full migration and are not included in standard Swift service fees.

• Validation Failures/NAKs: Messages must comply with Swift CBPR+ Usage Guidelines; mismatches or missing data will result in rejections (NAKs).
• Testing: Use Swift’s MyStandards and FINplus Pilot services for thorough testing prior to cutover.
• Continuous updates: Ensure that your institution keeps up to date with future standard releases and new features, most of which will only be available in ISO 20022.

gpi tracking via MT 199 and MT 299 is still available post-November 2025. However, new tracking features are only being developed in the ISO 20022 trck message or API formats. Institutions are encouraged to migrate their payment tracking to ISO 20022 to leverage enhanced services.

• Assess all impacted systems, applications, and processes for ISO 20022 readiness.
• Engage in rigorous end-to-end testing with Swift partners and counterparties.
• Provide comprehensive training for operational and compliance teams.
• Communicate with clients about changes in remittance data requirements or formats.
• Monitor Swift and industry communications for updates or mandatory changes.

As part of the ISO 20022 migration, Swift and industry groups are tightening how postal addresses are used in payment messages. During the initial migration, structured, hybrid, and fully unstructured addresses may be used; however, beginning in November 2026, fully unstructured postal addresses will no longer be permitted in CBPR+ payment messages, and only structured or hybrid addresses will be accepted. At a minimum, hybrid addresses must include Town/City and Country in dedicated fields.

Yes. PCBB adopted ISO 20022 for international/Swift cross-border payments in line with the November 2025 cutover and continues to operate on the new standard. We are also preparing for the next phase of ISO 20022 changes, including the November 2026 updates related to structured and hybrid postal addresses and other industry enhancements, so that clients can continue to rely on a smooth, standards-aligned experience.

You will see there is more opportunity for detailed data, better transparency and tracking, and improved fraud prevention and compliance as a result of Swift’s ISO 20022 migration and PCBB’s support of that standard. Over time, additional ISO 20022 enhancements will be introduced, including industry-wide requirements for structured or hybrid postal addresses beginning November 2026 onward, which are designed to further improve data quality and reduce exceptions.

PCBB is committed to making the transition to ISO 20022 for international (Swift) wire payments as seamless as possible for CBC users. If you use PCBB’s CBC platform for international wires, please refer to our ISO 20022/Swift Resource Center for the latest updates and guidance on this transition.
