MANDATING THE PHILIPPINE POSTAL CORPORATION TO ADOPT A 
MODERNIZED ZONE IMPROVEMENT PLAN CODE SYSTEM
The Zone Improvement Plan (ZIP) Codes in the Philippines play a crucial role 
in facilitating an efficient sorting and delivery of mail and parcel. ZIP Code is composed 
of four-digit number that represents a specific locality. The use of ZIP Codes improved 
postal services and reduced sorting and delivery errors.
Over the years, the traditional postal customers have changed significantly. The 
use of internet, eCommerce and the digitalization of consumers contributed to these 
changes. While ZIP Code indeed helps in simplifying sorting and delivery of mail and 
parcel, there is a need for it to be redesigned to address the needs of the present and 
future customers. Modernizing the ZIP code system \n\W upgrade and improve the 
efficiency of address-based services across various industries.
Thus, this bill seeks to institutionalize a modernized alphanumeric ZIP Code 
system in the country. This will enhance domestic delivery services by the Philippine 
Postal Corporation (PHLPost), improve logistics efficiency, and streamline business 
operations. This will also enable more precise address mapping, reducing delivery 
errors, and optimizing last-mile logistics particularly in remote barangays. Moreover, 
this will also enhance disaster response efforts and improve the delivery of essential 
public services, particularly in geographically isolated and disadvantaged areas.
In view of the foregoing, the approval of this bill is earnestly sought.
MARK A. VILLAR ^
