SOCCSKSARGEN (Region 12)
SOCCSKSARGEN (Region XII), formerly Central Mindanao, is located in the south-central portion of the island. It consists of the provinces of Cotabato, Sarangani, South Cotabato (which was used to be part of Region XI), and Sultan Kudarat, plus Cotabato City. The names of the provinces together with General Santos City spell the name of the region which is an acronym. Cotabato City, which is surrounded by, but is not a part of Maguindanao province, was the region's former administrative center. Koronadal City, in South Cotabato, is the new administrative center of the newly formed region.
