But now I am in email contact with someone who has compiled his own lists of municipalities and subdistricts, and then cross-checked then with my spreadsheet. Quite helpful, it showed several cases where I had small mistakes within my lists, as well as clearing up some in his lists. He had a few more subdistricts in his list than me, and I also had a subdistrict named Som Kai (ตำบลสมก๋าย) in Chiang Mai listed as an active subdistrict, even though it was one which was not created, but got a the geocode 50061400 assigned already. But after removing that one, I noticed I still have one subdistrict too much - the corresponding sheet had 7425 subdistricts, thus 7256 Tambon.
Checking with the population numbers from DOPA, the additional Tambon stayed, apparently there are 7256 populated Tambon. Next step then was to check with a Excel sheet showing the subdivision numbers for each province, which also had 7255 Tambon altogether - and with that one I could nail it down to be Nakhon Si Thammarat province to have the additional subdistrict. According to that spreadsheet (and several other sources), the province has 169 Tambon - actually a lot of source show a number of 165, even the website of the province administration itself, which is even more wrong. But I have 170 Tambon, and with a 2003 book listing all the Muban I was able to find the culprit - Pak Phanang district is listed there without the subdistrict Pak Phanang (ตำบลปากพนัง). The only thing special about that subdistrict is the fact that it is completely covered by the town Pak Phanang (เทศบาลเมืองปากพนัง), and thus has no subdivision in to Muban anymore, nor any village or subdistrict headmen. But that is not unique to this Tambon, there are several of this kind in larger towns or cities. In fact, the subdistrict was identical with the area of the town until the town was enlarged in 1993 [Gazette].

If anyone can help to clear up this confusion I would be happy, so far I can only find that something is very odd around there.
