Nacha's definition

The RDFI/Gateway has determined that the Entry must be returned to comply with its sanctions compliance obligations.

Verbatim from Nacha — rule page 'New Return Reason Code for Sanctions Compliance Obligations' (R90; effective 17 March 2028). Applies to: Not stated on the rule page.

Reinitiation conditions

R90 is not effective until 17 March 2028. For any future returned debit, this code alone does not establish permission to reinitiate. Confirm the current Rules and the return reason with your ODFI before any further entry.

How it appears in an ISO 20022 statement

R90 postdates Nacha's August 2023 ISO 20022 mapping guide and has no published camt.053 mapping.

Return time frame

Not yet in force. Nacha's rule page gives R90 an effective date of 17 March 2028, and states the return must be made available to the ODFI no later than the opening of business on the second Banking Day following the RDFI's sanctions compliance determination. Until then, an OFAC-instructed return continues to use R16.

What an operator does next

Nothing to do yet except plan: from 17 March 2028 a sanctions return will arrive as R90 and R16 reverts to meaning a frozen account only. If your exception handling treats every R16 as a possible OFAC hit today, keep doing so until then.

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

Nacha's credit-push fraud rules: an operator reference

Covers R06 (ODFI Request for Return), the R16/R90 sanctions framing, and the 2026–2028 rule timetable.
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.
