NACHA's ISO 20022-to-ACH Mapping Guide & Tool: enables financial institutions to support businesses that leverage ISO 20022 by providing standardized guidance to facilitate translation of ISO 20022 pain.001 (credit) and pain.008 (debit) messages into ACH transactions, and by providing standardized guidance for translating ACH reject/return messages to corresponding ISO 20022 payment status and treasury reporting messages (pain.002 and camt.053).

About ISO 20022 and NACHA’s ISO 20022 Mapping Guide & Tool
ISO 20022, which was developed by the International Organization for Standardization (ISO), is the global messaging standard for financial business transactions, including payments.  Today, many multinational companies are utilizing this standard as part of their accounts payable, accounts receivable and treasury functions. In order to facilitate the integration of ISO 20022 payment messages, NACHA has developed an ISO 20022-to-ACH Mapping Guide & Tool to assist financial institutions in translating ISO 20022 instructions for their corporate customers into ACH transactions.

How it Works
Utilizing the ISO 20022-to-ACH Mapping Guide & Tool, financial institutions can receive an ISO 20022 pain.001 or pain.008 message and translate the messages to corresponding ACH Network business and consumer transactions, including CCD, CTX, PPD, IAT and Same Day ACH. The ISO 20022-to-ACH Mapping Guide & Tool also facilitates the translation of ACH return/reject transactions to corresponding pain.002 and camt.053 messages to support clients that wish to receive ISO 20022 messages for these use cases. As part of its ISO 20022 integration strategy for the ACH Network, NACHA will continue to explore options to extend its mapping guidance to address additional industry needs to help bring the benefit of consistency to all organizations and payments.
