What is Thai Postal Code Lookup?
The Thai Postal Code Lookup is a free browser-based tool for finding Thailand postal codes. It searches a bundled dataset of 7,436 subdistricts across 77 provinces and 928 districts, letting you go from a location name (in Thai or English) to its 5-digit postcode, or from a postcode to the full list of subdistricts it covers. All processing happens locally — nothing is uploaded.

Frequently Asked Questions
How many postal codes does the tool cover?
The bundled dataset covers 7,436 subdistricts (tambon/khwaeng) across all 77 provinces and 928 districts (amphoe/khet) of Thailand, including Bangkok special-administration districts.
Can I search in Thai as well as English?
Yes. Every location is stored with both its Thai and English name, so you can type either language — or even a partial name — and results display both forms side by side.
Does one postal code always map to exactly one subdistrict?
No. In many areas a single postal code covers several neighboring subdistricts (for example 10230 covers both Lat Phrao and Chorakhe Bua in Bangkok). Searching by number lists every location that uses it.
Is my search sent to a server?
No. The full postcode database is bundled with the page and searched entirely inside your browser. Nothing you type is transmitted anywhere, and the tool keeps working offline after the first load.
