Prenote Date

Mnemonic: DADTAP

The date the prenotification was sent for the incoming ACH transaction selected in the Incoming ACH list view. A prenote is the commonly used term for an Automated Clearing House (ACH) prenotification.

Prenotes are optional for an originating company, but they are not optional for the receiving institution (the RDFI, or receiving depository financial institution) once the originating company sends one. Under the ACH rules’ National System of Fines, an RDFI can be fined if they do not validate prenotes sent to them.

Under NACHA Operating Rules (also known as ACH rules), a prenote’s purpose is to "validate" the routing number and account number of the receiving financial institution.

This information is entered by the system when an ACH transaction is cleared during the afterhours.
