About this dataset
Postal Codes Dataset for Luxembourg (LU)
This dataset lists Luxembourg postal codes with place names, cantons and communes, covering every canton and commune. Luxembourg's postal source has no third administrative tier, so this is full coverage of both tiers that exist.
Column definitions, row count, size and last-updated date are in datapackage.yaml.
Data Sources
- Postal codes, place names, cantons, communes and coordinates: © GeoNames postal code export for Luxembourg, CC BY 4.0.
Changes made to the source data: canton codes given as ISO 3166-2:LU (the LU- prefix added to GeoNames' own canton letters).
Not endorsed by, or affiliated with, GeoNames.
See ATTRIBUTION.txt for the full attribution notice.
Known limitations
- The source has no third administrative tier:
admin_name3andadmin_code3are empty on every row. - Primary key is (
postal_code,place_name,admin_name2). A border locality ("Blumenthal", postal code L-7639) is listed once per commune it touches (Bech in Echternach canton, and Junglinster in Grevenmacher canton), so (postal_code,place_name) alone repeats. admin_code2is a per-canton sequence number, not a globally unique commune code, soadmin_name2(commune name) is used as the key's third element instead.alternative_city_nameis empty.
