Taiwan Postal Code Format
Taiwan uses a 3-digit base postal code, which can be extended to 5 or 6 digits for more precise mail delivery. The first three digits identify the city or county, while additional digits specify districts, neighborhoods, or delivery routes. This six‑digit system was officially introduced in March 2020 to improve delivery precision. Before 2020, Taiwan used a 5‑digit system (3+2) and both systems are still recognized in practice.
- Special municipalities, cities, and counties are all top-level divisions
- Municipalities are not divided into counties
- Municipalities and cities are divided into districts
- Counties are divided into townships and county-administered cities
- Postal codes are assigned based on these divisions and their subdivisions
Taiwan is divided into 22 first-level administrative divisions, consisting of 6 special municipalities, 3 cities, and 13 counties. Each division has its own postal code range, making mail sorting and delivery efficient across urban, rural, and island regions.
