The postal division number is represented by the fourth digit of the postal code
Postal branches are divided into many divisions, each branch consists of maximum number of nine divisions. Divisions are almost equally divided.
Areas of divisions may differ due to the following reasons:
- Geographical and terrain factors between postal divisions.
- Density of population in a given division.
- Divisions of any branch are divided according to main roads and streets, and interconnecting streets, according to street categories.
- Coding of postal divisions is based upon the nearest division to the axis of the division, where smaller numbers are assigned to postal divisions which are the closest to the axis lines. The numbers increase as we move far from the axis.
