Investopedia explains 'National Automated Clearinghouse Association - NACHA '


Although not a government agency, NACHA works closely with all interested government agencies (including the Federal Reserve, the state banking authorities and the Treasury) to ensure the integrity of the electronic payments systems used by banking and other depositary institutions.

NACHA not only develops rules and codes of business practices, but it is involved in the development of new applications. It also institutes and monitors quality- and risk-management controls. Over 18 billion ACH payments were processed in 2007.
