Given the ACH Network’s ability to support ISO 20022 messages, NACHA has been leading efforts for a number of years to develop programs and tools to educate, support and encourage use of the standard.

NACHA —The Electronic Payments Association® announced today that it has published an enhanced version of its ISO 20022-to-ACH Mapping Guide to assist financial institutions in translating ISO 20022 payment instructions into ACH payments for their business customers. The Guide, which previously only provided information to map ISO 20022-formatted payment messages to corresponding ACH Network business credit and international transactions, now includes instructions for mapping debit and additional credit transactions, rejections and returns, as well as Same Day ACH.

“Given the ACH Network’s ability to support ISO 20022 messages, NACHA has been leading efforts for a number of years to develop programs and tools to educate, support and encourage use of the standard,” said Janet O. Estep, president and CEO of NACHA. “To continue to meet the evolving needs of the industry as more organizations seek to leverage ISO 20022, we are always looking to refine and create the tools necessary to support those needs. NACHA’s enhanced ISO 20022-to-ACH Mapping Guide serves as another valuable resource to support the seamless and consistent integration of ISO 20022 across organizations as they look to enhance and improve operational processes.”

ISO 20022 is the standard for financial service messaging used to describe business processes, such as payments, developed by the International Organization for Standardization (ISO), an international standard-setting body. The ISO 20022-to-ACH Mapping Guide, developed in collaboration with financial institutions, corporations and industry subject matter experts, helps financial institutions support their global customers that need to execute U.S. ACH payments by outlining the mapping of ISO 20022 payment files to ACH transactions. Specifically, the enhanced Guide provides instructions on how to translate ISO messages to ACH Network business and consumer transactions – both credit and debit transactions – as well as returns and rejected items, and Same Day ACH.

“We commend the leadership role NACHA has taken with respect to ISO 20022 industry education and support,” said Gordon Skjeie, first vice president, DNB Bank ASA. “The resources they have developed, including the ISO 20022-to-ACH Mapping Guide, have provided the tools we need to successfully support our growing base of customers that want to efficiently execute ACH payments. These types of tools allow us to continue to serve as that valued resource to our corporate customers.”

“NACHA’s mapping effort is the product of diligent work with the key industry stakeholders leading the adoption of the ISO 20022 standard in the U.S.,” said Nasreen Quibria, Managing Director & Founder of Qinsights, the organization that worked with NACHA to develop the Guide. “Understanding their approaches helped in building a harmonized resource that will ultimately result in more consistent data exchange between corporations and their banks.”

As part of its ISO 20022 strategy for the ACH Network, NACHA will continue to develop tools and resources and provide educational opportunities to support integration of ISO 20022. Additionally, NACHA will continue to work together with the industry to explore options for greater integration via mapping and/or incremental changes to the ACH Network to help bring the benefit of consistency to all organizations and payments.
