Taiwan Address Format Guide
Taiwan's postal code has used a 3+3 format since 2020: the first 3 digits identify the district (township/city district), while the last 3 are assigned by Chunghwa Post based on the specific street and house number. Because that second half can't be derived from a simple rule and requires looking up Chunghwa Post's official database, this tool only generates the first 3 digits tied to the district as a format-reference test field — it does not produce, and cannot substitute for, the full official 3+3 lookup. Taiwanese addresses are written largest-to-smallest: city/county + district/township + road/street + lane/alley/number, similar in structure to mainland Chinese addresses.
Addresses generated by this tool for Taiwan are rule-based test data, not backed by a real geographic database. They are intended only for form validation, checkout flow testing, database population, UI prototyping, and localization testing — not for use as a real delivery address or identity proof.
FAQ
Does this site generate the full Taiwan 3+3 postal code?
No. The last 3 digits depend on the specific house number and require looking up Chunghwa Post's official database. This site only outputs the first 3 digits tied to the district, as a format-reference test value — for the full 3+3 code, use Chunghwa Post's official lookup tool.
Why can't the last 3 digits of a Taiwan postcode be generated directly?
The first 3 digits map to a district and can be listed directly, but the last 3 are delivery-route codes assigned by Chunghwa Post based on the actual street and house number — different house numbers on the same road can have different last-3-digit codes, with no public simple rule to derive them, so an official database lookup is required.
Does it cover all 22 counties/cities in Taiwan?
Yes, you can specify any county/city, or generate randomly.
Can these addresses be used for real deliveries?
No, the generated results are fictional test data intended only for format reference and development testing.
