Rahvastikuregister · Change services & bulk synchronisation cluster · Dec 2025 – May 2026

One change, all registers in sync — the technical basis of Estonia's once-only principle.

Change notifications, bulk data exchange and data-warehouse access. When an address or name changes, the population register propagates it to all dependent registers. The citizen reports a change exactly once — the rest happens automatically.
