These implementation guidelines ( ) set out the Single Euro Payments Area ( ) rules for implementing the Customer-to-Payment Service Provider (C2PSP) ISO 20022 XML message standards based on version 1.0 of the 2023 SEPA Direct Debit Business-to-Business (SDD B2B) rulebook, which enters into force on 19 November 2023.

  • Migration to the 2019 message version of the ISO 20022 standard.
  • Alignment of the attribute numbering between the four payment scheme rulebooks.

A list of main changes relative to version 2021 V1.0 has been included in the 2023 . In addition, a separate document (addendum) has been published which provides a detailed overview of all the changes.

An errata document, which lists an update to these , was published on 27 April 2023.

XML Schema Definitions (XSDs) related to the aforementioned are also made available. (Note: XSD files can be opened via a text editor (e.g. Microsoft Notepad) or XML Schema editor).

Disclaimer: XSDs are not developed for ‘production’ purposes, they are to instantiate the business rules and restrictions contained in the implementation guidelines in a formal interchange format, sometimes referred to as Technical Validation Subsets (TVSs). Production instantiations should refer to the default ISO 20022 namespaces.
