Digital shared-use service and core infrastructure on which many public policies are backed up, it is part of the state information and communication system and is therefore under the responsibility of the Prime Minister**.

Under co-piloting DINUM, ANCT and IGN, its construction is ensured thanks to many partners and in the first place by the communities, only competent authorities in terms of addressing.

The National Address Base is accessible as files and APIs.
