ISO 20022-7:2013 specifies the responsibilities of the following bodies, which are involved in the registration and maintenance of the ISO 20022 Repository.

• The Registration Authority (RA) is the operating authority responsible for the registration and maintenance of the ISO 20022 Repository and for providing access to the information described in ISO 20022-1:2013. The RA is assisted by different Standards Evaluation Groups (SEG), i.e. groups of industry experts responsible for specific Business Areas of the Repository.
• A Technical Support Group (TSG) advises the SEGs, the RA, developers and communities of users on the technical implementation of ISO 20022.
• The Registration Management Group (RMG) is the governing body of the overall registration process and the appeal body for the communities of users, Submitting Organisations, the RA, the SEGs and the TSG. It monitors the registration process performance.
