Alongside them are various IMI coordinators who support the final authorities. They perform essential work both to ensure the construction, training and maintenance of the network of authorities, and to provide greater specialization in cases that require intervention (such as differences of opinion with other states, treatment of alerts, etc. ).

In Spain, in addition to the mandatory national coordinator (NIMIC), 'thematic' coordinators have been appointed for each directive of the General Administration of the State, and 'global' coordinators for each of the CCAA and cities with autonomous status authorized for all directives.
