Paluka Samo (ปะลุกาสาเมาะ) is an administrative subdistrict of Bacho, with code 960304. Ton Sai Municipality occupies part of the tambon, while the subdistrict administrative organisation serves the area outside that municipal boundary. These overlapping local-government names do not refer to a different district. Royal Development Projects Board records describe water-management work supporting rice-growing communities around Ban Ton Sai and Ban Bue Nae Bi Yae, illustrating the importance of irrigation and drainage in the local landscape.
For a village visit or an official appointment, use the named settlement and its full Bacho address. A destination within the Ton Sai municipal area may be served by a different local authority from one elsewhere in Paluka Samo. The map reference identifies the tambon geographically, rather than the municipal office, a temple entrance or an irrigation-project access point.
