Postal codes are used to identify specific locations. In Iran, the postal code is a 10-digit number, the first 5 digits representing the departure code (characteristic of the destination city) and the second 5 digits representing the distribution code (location characteristic of the destination).[3] Its main use is to send letters or postal packages sent by the Iran Post Company. There are currently about 52 million different postcodes in Iran.[4][5]
Postal code in Iran is issued by the General Geographical and Spatial Administration of the country under the supervision of the National Post Company.[4][5]
The plan to allocate and use the 10-digit postal code was included in the agenda of the Government and the Islamic Consultative Assembly of Iran in 1991. Therefore, during a 5-year period, from 1991 to 1996, they began to collect statistics and informations, and in 1997, they announced 10-digit postal codes for all Iranian places and households.[6]
