ANCOM is headquartered in Bucharest, and has five other regional divisions: Bucharest, Cluj, Muntenia, Timis and Iasi, as well as a county office in each county capital city.

Their role is to ensure that the competences of ANCOM are exerted in the territory, as well as to receive requests and notifications from consumers in order to solve them or to send them to the ANCOM headquarters for resolution, as the case may be.

In fulfilling its role and legal duties, ANCOM consults and collaborates with the Competition Council and the National Authority for Consumer Protection, including by mutual provision of information necessary for the enforcement of the legal provisions both in the competition field, and in the field of electronic communications and of postal services.

The Authority is under parliamentary control.
