SEPA Instant Credit Transfer Scheme Customer-to-PSP Implementation Guidelines 2021 version 1.0

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 the versions 1.0 and 1.1 of the 2021 Instant Credit Transfer ( ) Rulebook.

An errata document was published on 31 May 2021, which lists a couple of updates to these and the related updated XSDs were published on 11 June 2021.

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.
