Switzerland traditionally uses a 4-digit postal code system, but the 6-digit postal codes extend this system to provide a more precise geographic granularity, often down to specific delivery points or smaller administrative units. These extended codes help businesses, logistics companies, and government agencies with detailed spatial analysis and routing.
Switzerland does not use the term ZIP codes; instead, postal codes ('Postleitzahl' or PLZ) are used. The 6-digit postal codes are an extension of the official 4-digit PLZ, designed for more detailed location referencing.
This dataset uses six-digit postal codes, which build upon the standard four-digit Swiss postal codes by adding two extra digits for more precise geographic segmentation.
The first four digits correspond to the official Swiss postal code areas, and the additional two digits specify sub-regions or particular delivery points within those areas, enabling high-precision mapping and mail sorting.
Six-digit postal codes in Switzerland start with the official 4-digit codes ranging roughly from 1000 to 9658, followed by two digits from 00 to 99 to denote finer location details within those zones.
| 4-digit Prefix | Region / Example City |
| 1000 | Lausanne |
| 1200 | Geneva |
| 3000 | Bern |
| 4000 | Basel |
| 6000 | Lucerne |
| 8000 | Zurich |
| 9000 | St. Gallen |
The last two digits specify smaller zones within these main areas.
| Example | Area |
| 1000 01 | Lausanne - specific delivery point |
| 1200 45 | Geneva - specific district |
| 3000 22 | Bern - sub-area |
| 4000 78 | Basel - particular zone |
| 6000 05 | Lucerne - delivery section |
| 8000 11 | Zurich - local postal route |
| 9000 99 | St. Gallen - fine-grained segment |
