Nacha's definition

ODFI has requested that the RDFI return an Erroneous Entry, or a credit Entry originated without the authorization of the Originator.

Verbatim from Nacha — ISO 20022 Guide to Mapping U.S. ACH Return Items and Notifications of Change, August 2023, Version 2.01 (Table 1, return reason codes) (return reason code table). Applies to: ALL.

How it appears in an ISO 20022 statement

Nacha's mapping guide maps R06 to camt.053 reason code NARR (Narrative) — ISO definition: Reason is provided as narrative information in the additional reason information. Nacha marks this ISO code as mapped to more than one Nacha return code, so the ISO code alone does not identify the Nacha reason; read the narrative or the original return record.

Return time frame

Nacha's public rule pages refer to the standard "two-day" return time frame for returns that are not extended (unauthorized) returns. The governing time limit for this code is set in the Nacha Operating Rules, which Nacha sells and which were not used here, so it is not restated.

Can the entry be reinitiated?

Nacha's reinitiation rule governs resubmission of returned debit entries; it does not arise for this code. See the definition and the operator note for what the return means and who acts on it.

What an operator does next

Your own ODFI asked the RDFI to return this entry — an erroneous entry, or a credit sent without your authorization. Nacha's rule page records that since 1 October 2024 an ODFI may request a return for any reason, indemnifying the RDFI; that the RDFI's compliance remains optional; that the stated aim is recovering funds after fraud; and that from 1 April 2025 the RDFI must advise the ODFI of the request's status within ten banking days. Your ODFI is the party to talk to.

PaymentBrief guidance, not Nacha text. Your ODFI's procedures and the current Nacha Operating Rules govern.

How a returned ACH credit is triaged — repair, reissue or escalate — and why repair and retry are different decisions.
Confidence: high. Status: verified. The Nacha Operating Rules govern. Nacha sells them and they were not used here; every statement above is taken from a public Nacha document or a public US Treasury or Federal Reserve document, named per statement. Where those documents are silent, this card says so of those documents — it is not a claim about everything Nacha has published.
