Nacha's definition
The reference used to identify the Foreign Receiving DFI of an Outbound IAT Entry is invalid.
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: OUTBOUND IAT.
How it appears in an ISO 20022 statement
Nacha's mapping guide maps R82 to camt.053 reason code RC02 (Invalid Bank Identifier) — ISO definition: Bank identifier is invalid or missing. Generic usage if cannot specify between debit or credit account.
Return time frame
IAT and Gateway returns run to the time frames in the Nacha Operating Rules, which are not stated in the public sources used here.
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 foreign receiving DFI identifier is invalid. Validate the foreign bank identifier before origination.
