AN ACT
MANDATING THE PHILIPPINE POSTAL CORPORATION TO ADOPT A 
MODERNIZED ZONE IMPROVEMENT PLAN CODE SYSTEM
EXPLANATORY NOTE
A Zone Improvement Plan (ZIP) Code is a four-digit number that represents a 
specific locality. First introduced in the United States by the Postal Service in 1963, it 
was iater adopted by the Phiiippine Postai Corporation (PhiiPost). ZIP Codes 
significantiy improved postal services by minimizing sorting and delivery errors caused 
by illegible or incomplete addresses. Currently, PhiiPost utilizes around 1,400 ZIP 
codes, which are assigned to cities and municipalities. The current ZIP Code system, 
however, is far from standardized. For instance, large cities often have multiple ZIP 
codes, while certain institutions, such as the Ninoy Aquino International Airport, are 
assigned their own unique codes.
Taking cognizance of the wisdom behind House Bill No. 11255, primarily 
authored and sponsored by Reps. Olivarez and Singson in the Nineteenth Congress, 
this proposed measure aims to assign a unique ZIP code to each of the 42,011 
barangays in the Philippines. By doing so, it seeks not only to enhance the delivery of 
mail but also to optimize the use of ZIP codes for providing basic services.
In light of the above, the swift approval of this measure is earnestly sought.
