ISO 20022-3:2026

ISO 20022-3:2013 describes the modelling workflow, complementing ISO 20022-1:2013 and ISO 20022-2:2013. The modelling workflow describes the required steps a modeller follows in order to develop and maintain standardized BusinessTransactions and MessageSets. ISO 20022-3:2013 is not intended to describe what will be the permissible artefacts and/or documents to be submitted to the Registration Authority (this information is contained in ISO 20022-7). Examples are provided only to illustrate the modelling methodology and are not normative.
