The EPC released version 8.0 of the document ‘Guidance on Reason Codes for SDD R-transactions’ in November 2024. This applies to the two current applicable 2023 Single Euro Payments Area (SEPA) Direct Debit (SDD) rulebooks, and to the two 2025 SDD rulebooks entering into force on 5 October 2025.
To give some background: one of the main benefits of the SDD schemes is that the scheme rules streamline exception handling, at both process and dataset level. This allows straight-through-processing and automated exception handling end-to-end. Possible exceptions to the normal execution of a direct debit collection include refunds, returns, rejects, refusals and reversals (commonly referenced as ‘R-transactions’ and described in detail in the SDD rulebooks).
The SDD Core and SDD Business-to-Business (B2B) rulebooks specify reasons which trigger an R-transaction, i.e. data elements required to convey information to the payee (biller) regarding the R-transaction. These data elements identify the type of R-transaction; name the initiator; and detail the reason for the R-transaction.
The correct application of these reason codes by a Debtor Payment Service Provider (PSP) (the PSP of the payer), informing a Creditor PSP (the PSP of the biller), about a failed SDD collection is crucial to allow the biller to determine its reaction.
Section 3 of the document provides guidance to SDD scheme participants about the reason codes to report specific SDD collection issues.
The changes covered in version 8.0 concern changes to reason codes RR02 and RR03. These two codes can also be used to highlight that the address formats of the payer and/or of the payee are invalid or are no longer supported.
