Postal codes in Taiwan
Postal codes (Chinese: 郵遞區號; pinyin: Yóudì qūhào; Pe̍h-ōe-jī: Iû-tē khu-hō) in Taiwan is a system of five digit codes used by Chunghwa Post for postal service in the Republic of China. There are 368 sets of three-digit codes for townships, county-controlled cities, districts (cities of Chiayi and Hsinchu have a single code covering all its districts) in Taiwan, and the uninhabited island groups of Dongsha (Pratas), Nansha (Spratly), and Diaoyutai (Senkaku) (currently controlled by Japan). There are also codes for Kinmen and Matsu, the parts of Fujian Province controlled by the Republic of China.
The first digit is for a large postal zone, as follows:
|First digit||Cities||Counties||Subsidiary islands|
|New Taipei, Keelung||Yilan, Lienchiang (Matsu)||Diaoyutai Islands|
|Hsinchu||Hsinchu, Taoyuan, Miaoli|
|Kaohsiung||Penghu, Kinmen||Dongsha Islands, Nansha Islands|
