Total Records4,470

Switzerland uses a numeric code of 4 digits (e.g. 8001). Four-digit postcode (NPA).

This database currently holds 4,470 postal codes ranging from 1000 to 9658, linked to 0 building and address records. Because a single postal code can cover more than one locality or delivery point, the lookup below groups addresses by code and lets you drill into the individual records.

Postal codes matter well beyond mail delivery. Couriers, e-commerce checkout forms and address autocomplete tools rely on the postal code to route a parcel and to verify that the stated address matches the code. Addresses here are organised as Canton → Municipality → Locality. When you look up a code here, treat the associated name as a reference point rather than a full postal address — always confirm the street and house number with the sender or recipient before shipping.

Data source: a third-party open dataset. This is an imported reference dataset, not a live government feed; CodeReff does not independently verify each record, so codes may have changed since the snapshot was taken. Use the search box to look up a specific code, or browse the paginated table below.

Frequently Asked Questions

Switzerland uses a numeric code of 4 digits (e.g. 8001). Four-digit postcode (NPA).

Yes. Switzerland postal codes are a plain numeric string, so a leading zero is part of the code itself. A code beginning with 0 must be written and stored with that zero — it is not the same as the same digits without it.
