The Pakistan Post reflects the organizational excellence that Pakistan boasts of providing smooth communication and postal deliverance within its large and diverse region. This system of a double-tiered system in the form of General Post Offices and attached post offices is further made stronger by the postal code system, which has a panoramic dimension.
Each element of the system works together as a bridge in distance and as a connecting instrument for millions. Let’s know how this complicated machinery works amidst the cultural and geographical diversities of Pakistan, which have been shaped and influenced by provinces.
Comprehending the Two-Tiered Structure of Pakistan’s Postal System
1. General Post Offices (GPOs)
General Post Offices are called account offices. They are the central spines of the postal system. All the main stations are situated in the big cities and act as operational nerve centers of that area. The job of the GPO is not only to sort and deliver mail but also money orders, savings accounts, and Postal Life Insurance.
For instance, Lahore GPO is one of the busiest centers in the country, and letters and packages meant for and from Punjab are processed efficiently. Similarly, Karachi GPO, Islamabad GPO, and Peshawar GPO are central to their regions’ operations.

2. Attached Post Offices
For example, such auxiliary post offices are under a GPO so that the services offered by the post office can reach people in different areas. Whether in a town or even a remote village, a post office attached to another one provides ease and efficiency. They go a long way in bridging areas that are otherwise inaccessible due to logistics.
Role of Postal Codes | Zip Codes | Postcodes in the Smoothing Delivery Process
Pakistan introduced postal codes in 1988. The five-digit numerical code assigned to the region or post office is what makes it easier for sorting and distribution. Each location had its unique code.
What Constitutes a Postal Code
The first two digits: The region or province is covered. For example, postal codes that start with “75” belong to Karachi, and a code starting with “54” means Lahore.
Remaining Digits: Identify which local post office or location in the area is to be used
This coding system would ensure proper routing, hence avoiding errors in processing and ensuring quicker delivery via mail, especially when mailed via rural areas.
