Iran - Postal codes


   Note: This section last updated 27th October 2018

Iran has replaced its 5 digit postal code with a ten digit code, intended to give an individual code to individual buildings in the country. The first digit is a forwarding code, the second a zone, the third a district, the fourth a part of the district, the fifth a segment. There are 8565 different five-digit zones. The final four digits are an identification code. The code cannot commence with a 0 or a 2 because of the resemblance of these numbers to other numbers in Persian writing.

Postal codes of post office boxes are five digits (the last one being 5) followed by a hyphen then the number of the box. Five-digit codes ending in 1 are for the "rural zones" of cities and for small towns and villages. Other codes, for larger cities, end in a digit between 6 and 9.
