Thailand is divided into 77 provinces, which constitute the primary administrative level of the country's two-tier system of territorial organization. Each province is governed by a provincial governor appointed by the Ministry of Interior, who oversees the implementation of national policies and coordinates various government agencies operating within the provincial boundaries. Provinces are responsible for delivering essential public services including education, healthcare, public works, and law enforcement, while also managing local infrastructure development and maintaining public order. They serve as the key intermediary between the central government in Bangkok and the district-level administrations below them, ensuring that national directives are carried out while addressing region-specific needs and concerns. Provincial administrations also collect certain taxes and fees, regulate local businesses, and maintain official records for residents within their jurisdiction.
