TWENTIETH CONGRESS OF THE ) REPUBLIC OF THE PHILIPPINES First Regular Session 25 JUL 14 A11:09 SENATE S. No. _ Introduced by Senator Francis G. Escudero 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 later adopted by the Philippine Postal Corporation (PhilPost). ZIP Codes significantly improved postal services by minimizing sorting and delivery errors caused by illegible or incomplete addresses. Currently, PhilPost 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. FRANCIS G. ESCUDERO
