ISO 20022 is a financial standard covering messages sent between different organizations. These messages include credit transfer and direct debits as well as payment status reports and account statements.

The messages are defined by ISO 20022 Universal financial industry message scheme (UNIFI) and are based on XML (Extensible Mark-up Language). Full definition of these messages from ISO 20022 web site: http://www.iso20022.org/. SEPA payment messages are a subset of certain ISO 20022 messages.

ISO 20022 is not the XML structure commonly implemented in payment systems today. ISO 20022 is a rich financial dictionary and methodology for creating financial standards from that dictionary. Whether used for traditional XML-based messaging exchange, or to support future JSON-based API services, ISO 20022 is agnostic of syntax or technology. Message Item - Element name used in ISO 20022 XML Message Definition Report. Tag Name - Name that identifies an element within an XML message. Is based on the ISO 20022 XML Message Definition Report. ISO Type - Indicates the ISO type Mult - indicates whether an element is mandatory or optional and how many repetitions are allowed for the element. Also included are detailed explanations and examples of the use of the message components to convey specific information related to these processes and activities. This guide acts as a supplement to the Message Definition Report and the XML schemas, which are published on the ISO 20022 website (www.iso20022.org). Work on implementing ISO 20022 is well underway in the APAC region (see Figures 1 and 2). Japan’s central bank, for example, has redesigned its real-time inter-banking.

CHICAGO--(BUSINESS WIRE)--The Federal Reserve today released message specifications for the initial launch of its FedNow Service for instant payments based on the standard set by the International Organization for Standardization, or ISO. The FedNow ISO 20022 specifications define the message flows and formats that the service will leverage when operational in 2023. The release of these specifications is an important step that allows financial institutions and other payments providers to begin preparing systems and developing solutions to support FedNow payments.

“Our work with payments industry stakeholders revealed unanimous support for developing our messaging specs in alignment with the ISO 20022 messaging standard to enable broad interoperability, end-to-end efficiency of payments and future innovation on top of the FedNow platform,” said Nick Stanescu, senior vice president and FedNow business executive. “Our adherence to the ISO 20022 standard means more opportunities for implementation across products and market segments.”

The Federal Reserve also collaborated with The Clearing House to optimize compatibility between the two U.S. instant payment services, which are likely to have common users across the industry. In addition, the individual FedNow message flows and implementation guidelines were validated by experts on the FedNow Community ISO 20022 Working Group and other industry participants in the FedNow Community, including participants from BNY Mellon.

“We were pleased to assist the Federal Reserve in developing messaging specifications that will best serve the banking industry’s needs for instant payments adoption and its long-term evolution,” said Mike Bellacosa, global head of payments and transaction services at BNY Mellon. “We were able to share insights from BNY Mellon’s experience as an instant payments pioneer with the Fed and other working group members, and look forward to continued collaboration with the Federal Reserve as members of its FedNow pilot program.”

Fiserv, an organization that provides financial services and payments technology globally and helps financial institutions connect to payment infrastructures, also took an active role in the FedNow ISO 20022 working group.

“The ISO 20022 message standard is currently used or planned for use by multiple payment systems around the world, an important factor for future interoperability,” said Matthew Wilcox, president, digital payments and data aggregation, Fiserv. “Consistent use of the ISO 20022 standard will enable Fiserv and other global payments stakeholders to leverage our existing investments in payments technology built on the ISO standard, facilitate payments efficiency and speed development of new products.”

Iso 20022 Message Format Example

The ISO 20022 standard is an internationally accepted messaging format that enables rich data exchanges, efficient end-to-end straight-through payments processing and interoperability with other payment systems. The messages supported in the initial launch of the FedNow Service will include customer credit transfer, request for payment, interbank liquidity transfer and administrative and account reporting messages.

The Federal Reserve is using the MyStandards^® platform to provide access to the FedNow ISO 20022 message specifications and accompanying implementation guide. The platform offers standards management tools for financial institutions and other payments service providers that plan to integrate their systems with the FedNow Service. For additional information on accessing the specifications, visit FedNow.org.
