Slovakia uses a postal code system known locally as PSČ (Poštové smerovacie číslo), which translates to 'postal routing number'. The format consists of five digits, typically written with a space after the third digit (e.g. 811 01), and is administered by the Slovak Post (Slovenská pošta).
The first digit of the code broadly indicates one of the eight regions of the country, with Bratislava and its surroundings generally starting with lower numbers. Larger cities often have multiple codes assigned to different districts or postal zones, while rural areas may share a single code across several small villages.
The database currently contains 1,414 postal codes for Slovakia.
