About this dataset
Postal Codes Dataset for Belgium (BE)
This dataset lists Belgian postal codes with place names, regions, provinces, arrondissements and WGS84 coordinates. It covers all regions, the provinces and the arrondissements, so it carries three administrative tiers above commune level.
Column definitions, row count, size and last-updated date are in datapackage.yaml.
Data Sources
- Postal codes, place names, administrative divisions and coordinates: © GeoNames, postal code export for Belgium, CC BY 4.0.
Changes made to the source data: region codes (admin_code1) and province codes (admin_code2) written as ISO 3166-2:BE codes (BE- plus the GeoNames letters), and arrondissement codes (admin_code3) kept as GeoNames' own 2-digit codes.
Not endorsed by, or affiliated with, GeoNames. See ATTRIBUTION.txt for the full attribution notice.
Known limitations
- Brussels-Capital Region has no province, so its province-tier code repeats its region code (
BE-BRU). - A small number of Brussels institutional or special-purpose postal codes (EU bodies, NATO, government) are not present in the source.
admin_code3(arrondissement) is GeoNames' own code, not an ISO code.alternative_city_nameis not populated.
