Flanders
In 2025, there will be new fusions between Flemish municipalities, see "Fusies 1.1.2025" on the VVSG website
Impacts:
- change of the province boundary at Beveren
- change of the municipality boundaries & possibly admin_centres
- lots and lots of streetname changes (and possible renumbering)
Preliminary data about the address changes is available at https://www.vlaanderen.be/digitaal-vlaanderen/onze-diensten-en-platformen/gebouwen-en-adressenregister/heradressering-bij-vrijwillige-gemeentefusies
About 350 streetnames are going to change! About 8000 addresses are affected, of which over 1300 also change housenumber.
The final merger decisions had to be made no later than December 31, 2023. This is the definitive list, as approved by the Flemish Parliament[1][2]:
