The Postal Code (ZIP) constitutes the main organization model of the Greek Postal Office (ELTA). Its establishment helped the Postal Office to make the processes of classification, transmission and performance of mail easier, simpler and faster.
Our country is divided into 21 postal regions (hubs). Each one of them contains one or more districts, which are determined by the first two digits of the five-digit Postal ZIP Code. Numbered postal areas are the basis upon which the classification and forwarding of all mail is founded on.
