- Develop the work pattern that Saudi Post has been working by for the past 30 years.
- Organize a modern addressing system to help and accelerate the sorting process and easily specify customers’ locations.
- Support E-Government and digital innovations in the Kingdom of Saudi Arabia.
- Provide everyone with an address by giving them a Zip Code and additional number for each house, building or commercial center and to be able to reach locations easily.
The method of coding for regions, sectors, branches and sections shall be made in accordance with the importance of each province and according to the priority of the administrative classifications of the Ministry of Interior, Governorate, Province A, B, Centers A, B. Digits “0” and “1” are for the use of the Post Service to cover post boxes, governmental centers and any others unexpected requirements that might arise in the future. Demographic densities of towns and their expected future growth have also been taken into consideration. For example: Riyadh Governorate is divided and coded into three sectors (2, 3 and 4) which are contained within the main sector of Riyadh.
After exhaustive study to reach very accurate results and taking into consideration all the above mentioned factors in the division operation, coding process is carried out as follows:
Postal Regions Coding Method which represents the first digit of the Postal Code:
The Region coding process has been carried out in accordance with the previous system, whilst preserving the main Region's divisions, which are as follows:
|The first digit of the postal code
||Region entering within the first digit of each postal code|
||Makkah Al Mukuramah Region |
||Eastern Region |
||Al Madina Al Munawara Region + Tabuk Region |
||Al Qassim Region + Hail Region |
||Asseer Region + Najran Region + Al Baha Region |
||Northern Boarders Region + Al Jouf Region |
||Jazan Region |
Sectors coding method which represents the third digit of the postal code:
The sectors coding process is carried out with the capital of the Region taking the digit ‘2’ and then the sectors north of the capital taking the odd numbers and the sectors to the south taking the even numbers which facilitates an easy guidance process for the sectors; the further the sector is North the higher the odd number, the further the sector is south the higher the even number.
Branches coding Method which represents the third digit of the postal code:
Each sector is divided into branches in the following manner:
Landlocked Sectors – A central point is chosen as the Axis Point. Areas to the East of the Axis Point are assigned the even numbers; areas to the West of the Axis Point are assigned the odd numbers. Numbering starts to the North of the Axis Point so the branches to the North East and North West of the central Axis Point have lower numbers than those to the South East and South West of the Axis Point.
Sectors that run parallel to the coast – The Axis Point is chosen as the most Southerly point on the coast of that sector and Branches are number sequentially Northwards.
Sectors that do not run parallel to the coast – The Axis Point is chosen as the most Southerly point on the coast and then the branches closest to the coastline are numbered with the even numbers, increasing the further North from the Axis Point they are, and the branches furthest from the coastline numbered using the odd numbers, increasing the further North from the Axis Point they are.
Postal Division coding method inside each Branch which represents the Fourth digit of the Postal Code
Divisions divide Branches into almost equal sizes depending on:
- Geographical Factors
- Population density
Divisions are divided on the basis of the Main streets and the interconnecting streets, with the closest Divisions to the Axis Point having the lowest numbers.
Quarter coding method inside each Division represents the Fifth digit of the Postal Code:
Each Division could be divided into a maximum of 9 quarters using the following rules:
- No quarter can be more than 4x4 kilometers square in dimension
- 2x2 kilometer squares are used for more populated quarters
- 1x1 kilometer squares are used for the most highly populated areas
The Eastern Axis (X) for each division will then be numbered 2000 to 5999 and the Northern Axis (Y) 6000 to 9999 in 1 meter blocks to provide a grid coordinate for every building in the Division. For Streets with an Easterly Direction the X coordinate will be used as the primary number and the Y coordinate the additional number with Buildings to the North of the street using the even number and those on the south side of the street using the odd numbers. For Streets with a Northerly Direction the Y coordinate will be used as the primary number and the X coordinate the additional number with Buildings to the East of the street using the odd numbers and those on the west side of the street using the even numbers. A road is considered to be Northerly rather than Easterly if its angle of direction is between 45º and 135º from East.
