List of postal codes in Hungary

Postal codes in Hungary consist of four digits. They were introduced on 1 January 1973. Each code denotes a post office of the "Magyar Posta" company.
The first digit identifies a geographic delivery area within Hungary. The second identifies a routing area. The third defines the route the mail takes either with the car/truck or with the train. The fourth stands for the post office outlet in the routing city.
Geographic delivery areas.
The geographic delivery area sometimes coincides with the county "(megye)", as shown in the table below.
In the capital Budapest, the second and third digit describe the district within the city (i.e. 1140: 14th district – Zugló).
