A notifying authority is a public body responsible for carrying out formal notification duties within a regulatory oversight framework. For conformity assessment, this can include notifying the relevant oversight system about bodies authorized to assess whether products or systems meet applicable requirements. It is distinct from a market-surveillance authority, which checks compliance in the market.
In cybersecurity and AI governance, the role matters because clear notification processes help regulators identify who may perform assessments and support accountability. In practice, organizations may need to provide conformity records and technical documentation when authorities request evidence. When several agencies share oversight, knowing which body handles notifications-and how it coordinates with other authorities-helps compliance teams route information correctly and respond without delay.
