Reinitiation of Debit Entries

Effective: 2015-09-18 Reinitiation is the method permitted in the Rules to resubmit a returned Entry.

Clarification on Prenotification Entries and Addenda Records

Effective: 2015-01-01 This Rule revises the NACHA Operating Rules to clarify that, with the exception of an IAT (International ACH Transaction) Entry, the Prenote Entry does not need to include addenda records that are associated with the subsequent live Entry.

There are, however, some differences between Prenotes and live Entries to which the Prenote relate: The dollar amount... Read More

NACHA Enforcement Authority

Effective: 2015-01-01 This new Rule adds more options for which NACHA may begin an initial investigation or Rules enforcement proceeding when an entity originates an excessive number of unauthorized Entries. This could result in increased investigations of Originator activity, and could ultimately result in fines passed on to those Originators. NOTE: We suggest that you review existing NACHA Rules regarding authorization requirements pertaining to originating ACH Entries to ensure your organization's compliance with the Rules.... Read More

Third Party Senders (TSPs) – Originator and Third Party Service Provider (TSPSs) audits required upon request by NACHA

Prenotification Entries

Effective: 2014-09-19 Reduction in Waiting Period for Live Entries - reduces the current six banking day waiting period between the initiation of a prenotification and "live' entries for originators choosing to originate prenotes. It also clarifies the originator's obligations with respect to a notification of change (NOC) received in response to a prenote.

Proof of Authorization for Non-Consumer Entries

Effective: 2014-09-19 Permits an RDFI to request proof of a non-consumer receiver's authorization for a CCD or CTX entry or an inbound IAT entry and details allowable methods by which an ODFI can satisfy the RDFI's request. The record or information must be provided to the RDFI within ten banking days without charge.

Editorial Clarification

Effective: 2014-03-21 Non-Consumer Receiver's Obligation to Credit Originator's Account - revises the text and title of Article Three, Subsection 3.3.1.3 (Non-Consumer Receiver Must Credit Originator's Account) to make the section's intent clearer and easier to understand for ACH Network participants.

Identification of Country Names within IAT Entries

Effective: 2014-03-21 Clarifies that any country named within various fields of an IAT entry must be identified using that country's 2-digit alphabetic ISO Country Code, as defined by the International Organization for Standardization's (ISO) 3166-1-alpha-2 code list.

Incomplete Transaction Clarifications

Effective: 2014-03-21 Clarifies that an ARC, BOC, or POP Entry may also be considered an incomplete transaction regardless of whether the account that is debited is a consumer account or a non-consumer account.

Use of the Tilde as Data Segment Terminator

Effective: 2014-03-21 Revises two IAT field descriptions, "Originator City and State/Province" and "Receiver City and State/Province", to clarify that, in addition to the backslash (\), the tilde(~) may be used as a data segment terminator. This Rules change allows consistent use of the tilde as data segment terminator for all entries.

ACH Security Framework

Effective: 2013-09-20 The ACH Security Framework establishes minimum data security obligations for ACH Network participants to protect ACH data within their purview.
