ISO 20022

ISO 20022 enables greater automation and straight-through processing, while reducing payments exceptions and risk. Nacha is leading efforts to promote ISO 20022 integration in the U.S. and helping stakeholders understand the benefits and implications for our industry.

About ISO 20022

ISO 20022 was developed by the International Organization for Standardization (ISO) and 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 functions. Use of the standard enables greater automation and straight-through processing, and can help reduce payments processing errors. It is important that financial institutions and other Network users understand the benefits of the ISO 20022 standard and its implications for the payments industry.
