Nacha's definition
The Identification Number used in the Company Identification Field is not valid.
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: CIE.
How it appears in an ISO 20022 statement
Nacha's mapping guide marks this code as not currently supported or mapped for camt.053 (footnote 1): it applies to Standard Entry Class codes or flows the guide does not cover, so it has no published ISO 20022 reason-code mapping.
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 page allows reinitiation "to correct administrative errors", with fields other than Company Name, Company ID and Amount modified only to the extent necessary. A corrected resubmission of a returned debit is therefore treated as a reinitiation, within the Rules' limits and carrying RETRY PYMT. Nacha's reinitiation rule addresses returned debits; a returned credit falls outside it.
correct the field the RDFI identified, and code the resubmission correctly.
What an operator does next
The Company Identification is not valid. Confirm the Company ID your ODFI assigned and use it exactly.
PaymentBrief guidance, not Nacha text. Your ODFI's procedures and the current Nacha Operating Rules govern.
