This EPC payment scheme enables euro credit transfers with the funds made available on the account in less than ten seconds at any time and in an area that will progressively span over 36 European countries. All payment service providers (PSPs) are invited to adhere to the scheme as soon as possible. The technical information for implementing the scheme is available on this page.
The SCT Inst rulebook currently in effect up to 17 March 2024 03:00 CET is the 2021 SCT Inst rulebook version 1.3. Version 1.3 has no specific impact on the business and operational rules compared to versions 1.1 and 1.2 of the 2021 SCT Inst rulebook.
The Implementation Guidelines of the 2021 SCT Inst rulebook are based on the relevant ISO 20022 XML message standards.

The 2023 SCT Inst rulebook version 1.2 enters into force on 17 March 2024 at 03:30 CET and is applicable up to 23 November 2025 08:00 CET. Version 1.2 formally replaced version 1.1 of the 2023 SCT Inst rulebook at its publication on 14 November 2023.
This entry-into-force time will be preceded by a SEPA-wide 30 minutes downtime period from 03:00 CET up to 03:30 CET. During that downtime period, no single SCT Inst instruction, transaction, r-transaction, transaction investigation and any response message related to them will be possible.
Up to 03:00 CET, all SCT Inst payment messages will be in the 2009 version of the ISO 20022 standard. As of 03:30 CET, all SCT Inst payment messages will be in the 2019 version of that same standard.
The Implementation Guidelines of the 2023 SCT Inst rulebook are based on the 2019 message version of the ISO 20022 standard.
The EPC also published a separate guidance document about the migration to the 2019 message version of ISO 20022.
- To formally enable the SCT Inst 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’ (PSU) including an appropriate definition for this new term. The definitions of the terms ‘Originator’ and ’Beneficiary’ are amended whereby also payment service providers (PSPs) 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 PSP as well. Also, some obligations of the Originator PSP and of the Beneficiary PSP in the rulebook sections 5.7 and 5.8 are amended.
- Provision of the structured address of the payment service user:
As of 17 March 2024 at 03:30 CET, payment service users are allowed to send a structured address of the Originator and/or the Beneficiary in electronic Customer-to-PSP files based on at least the EPC SCT Inst Customer-to-PSP Implementation Guidelines (IGs). From that same date, also SCT Inst scheme participants are allowed to provide structured addresses in their Inter-PSP SCT Inst payment messages and r-transactions.
In view of the above, all SCT Inst scheme participants must be able to support the delivery of structured addresses when payment service users and SCT Inst scheme participants want a structured address in their outgoing and incoming SCT Inst payments. SCT Inst scheme participants cannot reject SCT Inst payments only due to the inclusion of a structured address.
The use of an unstructured address will still be possible and supported by the SCT Inst scheme up to 23 November 2025 08:00 CET.
As of 23 November 2025 08:00 CET, the use of the structured address will become mandatory for Inter-PSP SCT Inst payment messages where applicable, and for payment service users when they send electronic Customer-to-PSP files based on at least the EPC SCT Inst Customer-to-PSP IGs. From that moment, the use of an unstructured address will no longer be allowed and will hence lead to rejects.
- Extra clarifications about the charging principles.
- Inclusion of the Proxy/Alias of the payment account of the Originator and/or of the payment account of the Beneficiary as an optional attribute in certain datasets. This attribute is an element supplied by the Originator and cannot substitute the IBAN as unique identifier for a payment account.
Important reminder: back in 2020, the EPC already decided upon the following changes for the 2023 SCT Inst rulebook:
- Migrate all ISO 20022 standard-based XML payment messages used under the SCT Inst scheme, to the 2019 version of the ISO 20022 standard. This migration now takes place on 17 March 2024 instead of 19 November 2023. More information about the change of this migration date can be found in the EPC news item published on 24 October 2023.
- Align the attribute numbering between the four SEPA payment scheme rulebooks as of the respective 2023 rulebooks.
Annex IV of the 2023 SCT Inst rulebook version 1.2 lists all changes since the version 1.0 of the 2021 SCT Inst rulebook.
