R06 - Returned per ODFI's Request
The Originator's own bank (ODFI) asked the RDFI to send the entry back, typically because the entry was erroneous or should never have been sent. The RDFI is not making a judgement here; it is honouring the ODFI's request.
R06 - Returned per ODFI's Request
The Originator's own bank (ODFI) asked the RDFI to send the entry back, typically because the entry was erroneous or should never have been sent. The RDFI is not making a judgement here; it is honouring the ODFI's request. This rejection is final: resubmitting the same payment will fail again — resolve the underlying situation first.
What this code means
The Originator's own bank (ODFI) asked the RDFI to send the entry back, typically because the entry was erroneous or should never have been sent. The RDFI is not making a judgement here; it is honouring the ODFI's request.
Typical causes
- Originator discovered it sent a duplicate or erroneous file and asked the ODFI to claw it back
- ODFI detected fraud or an origination error after transmission
- Reversal window was missed so the ODFI requested a return instead
What to do
Not a reinitiation scenario. The RDFI is not obliged to comply; if it does, the ODFI indemnifies it. Resolve directly with the ODFI before sending anything further.
What it looks like in an ACH return
The return arrives as an Addenda Record (type 99), 94 characters wide. The return reason code sits in positions 4-6.
