- Known limits
- Postcodes are a postal geography, not an administrative one; locality names are those of the directory (e.g. "Lausanne 25" for PO-box localities). Two rows point to communal-free areas, not political communes (1793 Jeuss → 2391 "Staatswald Galm", FR; 6809 Medeglia → 5391 "Comunanza Cadenazzo/Monteceneri", TI) and have no match in bfs-communes.
- Verification

Transformations
- Download the WGS84 CSV ZIP from the swisstopo STAC collection, read the single `;`-separated CSV (columns Ortschaftsname, PLZ4, Zusatzziffer, ZIP_ID, Gemeindename, BFS-Nr, Kantonskürzel, Adressenanteil, E, N, Sprache, Validity). Script: scripts/fetch/swisstopo-postcodes.ts
- postcode = PLZ4, locality = Ortschaftsname, bfs_number = BFS-Nr, canton = Kantonskürzel. Rows deduplicated on these four columns (the additional digit is dropped); sorted by postcode, locality (code-point order), commune.
- A postcode can belong to several communes (e.g. 9485 Nendeln → Eschen 7007 and Gamprin 7009); all are kept. To pick the main commune, use the address share in the raw file.
