Postal Codes were introduced in Pakistan on 1 January 1988 to speed 
sortation and delivery. These codes are for the delivery post office in 
whose jurisdiction the address falls. For example, for the entire 
Defence Housing Authority (DHA) area (all 8 phases), <a href="http://en.wikipedia.org/wiki/Karachi" title="Karachi">Karachi</a>,
 the delivery code is 75500. This code is not meant for the main DHA 
including post office's attached branch office. That code is +1 i.e. for
 DHA, the code is 75501. Another example is Lawrence College Post 
Office, whose delivery code is 47114. In that case, its attached branch 
office of +1 is 47115.<br />

Moreover, <a href="http://en.wikipedia.org/wiki/Azad_Kashmir" title="Azad Kashmir">Azad Kashmir</a>
 has also been post coded to Pakistani standards, but post code sequence
 00010 to 12991 has been deliberately left blank pending a final 
resolution of Kashmir issue.<br />

In 1947, it began functioning as the Department of Post & <a class="mw-redirect" href="http://en.wikipedia.org/wiki/Telegraph" title="Telegraph">Telegraph</a>. In 1962 it was separated from the Telegraph & Telephone and started working as an independent.<br />

The following is the list of some of the post codes within the 
country. GPO stands for General Post Office, the main post office in the
 city. For larger cities (Karachi and <a href="http://en.wikipedia.org/wiki/Lahore" title="Lahore">Lahore</a>),
 there are a number of GPOs; however the main one is the only one which 
has just the city's name attached to it (Karachi GPO and Lahore GPO). 
When evening postal services are offered, the name changes to NPO (Night
 Post Office).
