Administrative facility BSN

The administrative facility citizen service number (in Dutch: Beheervoorziening burgerservicenummer, BV BSN) is in charge of generating, issuing, managing, and consulting the citizen service number (BSN). The BV BSN controls access to the identifying data in the underlying authentic registers (Municipal Key register Personal Data, or GBA in Dutch, and the Non-residents Records Database). It also controls access to the verification registers for identity documents, to verify identity at the counter.

BAG

The Key register Addresses and Buildings (in Dutch: Basisregistratie Adressen en Gebouwen, BAG) contains municipal basic data of all addresses and buildings inside the municipality. Copies of these data are collected in a National Facility (Landelijke Voorziening, BAG LV). The Dutch land registration organisation Kadaster manages the BAG LV, and provides data to public offices, institutions, companies, and private citizens. The Minister of the Interior and Kingdom Relations is responsible for the BAG system.

BRK

The Key register Kadaster (Basisregistratie Kadaster, BRK) consists of the cadastral registration and the cadastral map (Kadastrale Kaart). The cadastral data are used by many clients as the foundation for their own work processes. In that sense, the Kadaster has been a key register for a long time. The Kadaster’s products remain available through MijnKadaster and the other channels. Direct links to other key registers will enable incorporation of the data of other registers into the cadastral register and products.

BRO

The Key register Subsoil (Basisregistratie Ondergrond, BRO) is to become the central database containing all public data on the Dutch subsoil. The BRO Act, which came into effect on 1 January 2018, requires that source data owners provide and use soil and underground data in a digital form. The requirements will be expanded step by step in the next 4 years. The data in this key register have been validated and are of importance for activities like fresh water procurement, underground transport, and mineral mining, but also for activities on the surface, like energy transition, housing construction, and infrastructural projects.
