Switzerland's Postal Code Format

Switzerland uses an "NPA" system, which is a four-digit numeric format, like 9999, with no letters or separators. This is similar to US ZIP codes, which are also numeric, but US ZIP codes are five digits long compared to Switzerland's four. According to the GeoPostcodes world postal code database, Switzerland has 3,333 postal codes covering 2,287 regions and 5,394 towns.

  • NPA Format: 9999

    • Numeric format, 4 digits
    • Based on postal routing districts rather than administrative hierarchies
    • In some larger cities, an additional two digits distinguish special delivery areas (e.g., P.O. Boxes)
    • 3,333 postcodes covering 2,287 regions and 5,394 towns

    Example:

    • 8000 - Zürich

  • Structure of Postal Codes

    • Format: 9999, numeric
    • Hierarchical levels: Not aligned with administrative divisions; postcodes are based on postal routing districts.
    • Key challenges: A single postcode can span multiple municipalities and even multiple cantons; a municipality can have multiple postcodes; postal codes may follow railway lines or postal bus routes; postcodes do not indicate any administrative hierarchy.

  • Management & Authority

    • Primary postal authority: Swiss Post, www.post.ch.
    • Update frequency: Monthly.
    • Other source: SwissTopo, a geographical/statistical authority.

  • Addressing Standards

    • Common address format: [Street Name] [Street Number], [Postal Code] [City]
    • Example address: Bahnhofstrasse 1, 8001 ZÜRICH

  • Special Characteristics

    • Four official languages in the country.
    • Postcodes can cross cantonal and municipal boundaries.
    • Some foreign localities (Germany, Italy) are served by Swiss Post.
    • Liechtenstein postal data is managed by Swiss Post.
