Nacha's definition
Account number structure is valid and it passes the check digit validation, but the account number does not correspond to the individual identified in the Entry, or the account number designated is not an existing account i.e., not an open account.
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, EXCEPT ARC, BOC, POP.
Reinitiation conditions
Nacha's reinitiation rule page says the rule "will allow reinitiations to correct administrative errors", with fields other than Company Name, Company ID and Amount modified only to the extent necessary to correct an error — so Nacha's page treats a resubmission with corrected account details as a reinitiation — within the Rules' limits and carrying the RETRY PYMT description — unless the Originator obtains a new authorization after the return, in which case Nacha does not treat the debit as a reinitiation.
get the corrected details from the Receiver, and decide deliberately whether you are reinitiating or originating a freshly authorized entry.
How it appears in an ISO 20022 statement
Nacha's mapping guide maps R03 to camt.053 reason code BE01 (Inconsistent with End Customer) — ISO definition: Identification of end customer is not consistent with associated account number
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 current Nacha Operating Rules and your ODFI determine the applicable deadline for this code; a general public two-day reference is not a substitute for that code-specific requirement.
What an operator does next
The account number has a valid structure, but the account is not located or does not correspond to the identified Receiver. Verify both account and Receiver details through a trusted channel before any new entry. The code alone does not prove a typo; apply the applicable validation and reinitiation requirements with the ODFI.
PaymentBrief guidance, not Nacha text. Your ODFI's procedures and the current Nacha Operating Rules govern.
Closed, unlocated or malformed?
These codes identify different account problems. A valid format is not proof that an account exists or belongs to the Receiver.
- R02 — Account Closed: stop entries to the closed account; obtain and authorize a replacement through a trusted channel.
- R03 — No Account / Unable to Locate Account: validate the Receiver and account relationship; do not assume the format is wrong.
- R04 — Invalid Account Number Structure: correct verified source data; do not guess digits.
PaymentBrief comparison of the definitions above. Repair is not automatic retry permission: check the reinitiation conditions and your ODFI’s procedures before a new entry.
