ISO 20022 Message Definitions


This section gives access to the documentation related to the ISO 20022 message definitions

Please note that the Message Definition Reports (MDRs) and Message Usage Guidelines (MUG) are available at the level of the message set, not at the level of the message definition itself.

To download the MDRs, MUGs, schemas and any additional documentation, you have to select a message set (Account Switching, for example).
