CH Postal Code & Address Builder

Swiss postcodes are 4 digits and don't match city names. Get the format right so your postcard, parcel or hotel mail arrives the first time.

What this solves

Swiss postcodes are 4 digits and don't map 1:1 to cities. The city of Zürich alone has 32 postcodes (8001–8099). Geneva has 8. Bern has 4. Get the wrong one and the parcel arrives at the wrong depot — usually still in Switzerland, but delayed 2–5 days.

This tool generates the canonical Swiss Post format (name on line 1, street on line 2, CH-XXXX City on line 3) plus the international variant and validates the postcode against known canton ranges.

How to read the output

What this tool ignores

Common questions

Does Swiss Post deliver on Saturdays?

Yes — Priority letters and parcels (A-Post / B-Post) usually arrive Monday–Saturday. Economy letters without tracking arrive Monday–Friday only.

Can I send a parcel from a hotel?

Yes. Most Swiss hotels sell postage stamps and accept pre-paid parcels at the front desk. Drop-off at the nearest yellow PostFinance/Post mailbox is also free.

What about the special FL postcode for Liechtenstein?

Liechtenstein uses 4-digit FL-9490 codes (Vaduz = 9490). Swiss Post delivers to Liechtenstein using the same system. If you're mailing from Switzerland to FL, address it FL-XXXX City.
