Open data for every province, district, subdistrict and postal code of Thailand, checked against official sources.
Search it at geothai.fasu.dev.
- Official codes from the Department of Provincial Administration (DOPA), with Thai and English names
- Postal codes per subdistrict. A subdistrict that spans post office zones gets more than one code
- Seven sources check every value. Each disagreement gets a decision and its evidence
- Abolished areas keep their code and the date they ended
- One JSON line per area, so the data works in any language
