Thailand's 928 districts (amphoe) constitute the second and final level of subnational administration, serving as the primary unit of local governance between the provincial and subdistrict levels. Each district is headed by a district chief (nai amphoe) appointed by the Ministry of Interior, who oversees civil administration, implements national policies, and coordinates government services within their jurisdiction. Districts handle essential public functions including civil registration, law enforcement coordination, land administration, and the delivery of basic government services to residents. They also supervise the tambon (subdistrict) administrative organizations and villages within their boundaries. The district office serves as the main point of contact between citizens and the central government, processing official documents, maintaining public records, and ensuring that national programs reach local communities throughout the country's diverse regions.
