Main changes introduced in the 2023 SDD Core rulebook
  • To formally enable the scheme to cater for both retail and Financial Institution-to-Financial Institution payment use cases, the term ‘Customer’ is replaced by the term ‘Payment Service User’ ( ) including an appropriate definition for this new term. The definitions of the terms ‘Creditor’ and ’Debtor’ are amended whereby also payment service providers ( ) can take up these roles. Related to this, the definition of the term ‘Payment Account’ is changed indicating that such account can be held by a as well. Also, some obligations of the Creditor and of the Debtor in the rulebook sections 5.7 and 5.8 are amended.
     
  • Provision of the structured address of the payment service user:

    As of 19 November 2023, payment service users are allowed to send a structured address of the Creditor and/or the Debtor in electronic Customer-to- files based on at least the Customer-to- Implementation Guidelines ( ). From that same date, also scheme participants are allowed to provide structured addresses in their Inter- collection messages and r-transactions.

    In view of the above, all scheme participants must be able to support the delivery of structured addresses when payment service users and scheme participants want a structured address in their outgoing and incoming collections. scheme participants cannot reject collections only due to the inclusion of a structured address.

    The use of an unstructured address will still be possible and supported by the scheme up to and including 22 November 2025.

    As of 23 November 2025, the use of the structured address will become mandatory for Inter- collection messages where applicable, and for payment service users when they send electronic Customer-to- files based on at least the Customer-to- . From that date, the use of an unstructured address will no longer be allowed and will hence lead to rejects.
     
  • Extra clarifications about the charging principles.

Important reminder: back in 2020, the already decided upon the following changes for the 2023 rulebook: 

  • Migrate all ISO 20022 standard-based XML payment messages used under the scheme, to the 2019 version of the ISO 20022 standard.
     
  • Align the attribute numbering between the four payment scheme rulebooks as of the respective 2023 rulebooks.
