Aside from the Automated Clearing House network (which connects all the banks in the United States), there are three other players involved in ACH payments:
- The Originating Depository Financial Institution (ODFI) is the financial institution that initiates the transaction.
- The Receiving Depository Financial Institution (RDFI) is the financial institution that receives the ACH request.
- The National Automated Clearing House Association (NACHA) is the nonpartisan governmental entity responsible for overseeing and regulating the ACH network.
