Hungary uses a four-digit postal code system known locally as 'irányítószám', administered by the Hungarian Post (Magyar Posta). The codes were introduced in 1973 and are structured so that the first digit broadly indicates one of seven postal regions, with Budapest assigned codes beginning with 1.
Within Budapest, the second and third digits of the postal code typically correspond to the district number, making it possible to identify a specific district directly from the code. Other cities and towns are assigned unique four-digit codes that do not follow a strict hierarchical subdivision like some other countries, though smaller settlements often share codes with a nearby town or county seat.
The database currently contains exactly 3,040 postal codes for Hungary.
