Key Facts

Negros Island Region is a former administrative region in the Philippines that existed from 2015 to 2017, comprising the entire island of Negros and its outlying islands. Located in the central Philippines, this region was created by separating Negros Occidental from Western Visayas (Region VI) and Negros Oriental from Central Visayas (Region VII) to form a unified administrative entity for the entire island. The region covered approximately 13,350 square kilometers and had a population of around 4.4 million people during its brief existence. It was divided into two main component provinces - Negros Occidental and Negros Oriental - along with several highly urbanized cities including Bacolod, the regional center. The creation of Negros Island Region aimed to address the geographical and administrative challenges of governing an island divided between two different regions, though it was ultimately dissolved in 2017 and the provinces returned to their original regional affiliations. For those seeking detailed postal code information for the municipalities and cities within this former region, comprehensive data is available for both Negros Occidental and Negros Oriental provinces.
