Region XII
SOCCSKSARGEN: Region XII of Mindanao
SOCCSKSARGEN, also called Region XII, takes its name from its five areas: South Cotabato, Cotabato province, Sultan Kudarat, Sarangani, and General Santos City. It is located in south central Mindanao and faces the Celebes Sea to the south.
General Santos is the region’s best known city, serving as the country’s main center for tuna fishing and canning. It is an independent city separate from Sarangani. Koronadal, in South Cotabato, is the regional administrative center where government offices and services are based.
The interior of the region is just as important as the coast. Lake Sebu in South Cotabato is the home of the Tboli people, who are famous for their traditional T’nalak weaving. Cotabato province and Sultan Kudarat share a long border with the BARMM, and people here cross between the two regions every day for work and trade.
The 2024 POPCEN population is 4,462,776. Cotabato City and the 63 barangays now part of BARMM are excluded from that count. Cotabato City is geographically surrounded by Region XII but is administered under BARMM, which affects population comparisons across older datasets.
The region runs from deep sea tuna fishing in General Santos to Tboli weavers in the highlands and large corn and palm oil farms in the inland provinces.
Tuna exports from General Santos grew 31 percent in one year, reaching USD 514.47 million in 2025. The General Santos Fish Port Complex handles hundreds of thousands of metric tons annually, with pre-dawn unloading activity starting before 5 AM when fishing vessels return. Six large-scale canneries operate in the city, employing an estimated 200,000 workers across fishing, processing, and logistics roles. The European Union accounts for about 40 percent of Philippine tuna export volume, with Japan and the United States as secondary markets.
The June 2026 Sarangani earthquake, a magnitude 7.8 event on June 8, caused deaths, building collapses, and airport closure across General Santos and nearby provinces. The earthquake damaged 1,379 public schools across six regions and affected more than three million learners. The General Santos airport closed on June 8 and reopened for commercial flights on June 15 after CAAP emergency inspections.
Sultan Kudarat province is the Philippines’ primary oil palm growing area. Isulan municipality alone has 49,551 hectares of oil palm. The province also produces significant volumes of corn, with output reaching 92,371 metric tons in the fourth quarter of 2025. The municipality of Isulan has been identified as the country’s Oil Palm Capital based on farm area coverage.
