NACHA (previously the National Automated Clearing House Association) manages the development, administration, and governance of the ACH Network, the backbone for the electronic movement of money and data in the United States. It is funded by the financial institutions it governs. The ACH Network serves as a network for direct consumer, business, and government payments, and annually facilitates billions of payments such as direct deposit and direct payment. Used by all types of financial institutions, the ACH Network is governed by the NACHA Operating Rules, a set of rules that guide risk management and create certainty for all participants.
NACHA is not directly involved in the ACH transactions that flow to and from organizations and financial institutions, nor does NACHA send communications to individuals or organizations about individual ACH transactions. Various phishing scams have attempted to use references to NACHA to scam people or get them to install malware.
