Good to know

  • Why don’t I see my village?

    The list links postcodes to municipalities, as Statbel publishes them. A village or district with its own postcode is found through that postcode, under the name of the municipality it belongs to.

  • Where does the list come from?

    From Statbel, the Belgian statistics office, as open data under the CC BY 4.0 licence. The version and date are in the sources.

  • Is my search sent anywhere?

    No. The whole list is in the page; searching happens on your device.
