Postal codes in Taiwan

Greater postal zones of Taiwan

Postal codes (Chinese: 郵遞區號; pinyin: Yóudì qūhào; Pe̍h-ōe-jī: Iû-tē khu-hō) in Taiwan is a system of three + three digits used by Chunghwa Post.[1] There are 368 sets of three-digit codes for townships, county-administered cities, and districts in Taiwan.

The cities of Chiayi and Hsinchu have a single code covering all their districts. The uninhabited islands Pratas (Dongsha) and Spratly (Nansha) each have a single code. The uninhabited Senkaku Islands (Diaoyutai) (administered by Japan) have a code, but there are no deliveries.

Omitting the supplementary three digits is ordinarily acceptable, but using a six-digit code will speed the delivery of the mail.

Change from 3+2 to 3+3 postal codes

The official launch of three + three digit postal codes occurred on March 3, 2020,[2] in order to support more fine grained delivery section codes. The initial three digit division codes remain unchanged, only the supplemental two digits were updated to three digits. The previous three + two digit system had been in service for 29 years, since February 1, 1991.

As of November 2020, three + two digit postal codes are still in common use and accepted by the post office. A significant proportion of forms and systems provide space for only three + two digit postal codes.

There are apps for Android[3] and iOS/iPadOS[4] to look up the 3+3 postal codes.

Large Postal Code Zones

The first digit is for a large postal zone:

First digit Cities Counties Subsidiary islands
New Taipei City, Keelung Yilan, Lienchiang (Matsu) Diaoyutai Islands, Pengjia Islet, Mianhua Islet, Huaping Islet
Hsinchu, Taoyuan Hsinchu, Miaoli
Changhua, Nantou
Chiayi Chiayi, Yunlin
Kaohsiung Penghu, Kinmen Pratas Island (Tungsha/Dongsha), Nansha Islands
Pingtung, Taitung, Hualien Qixingyan


Of the disputed territories, it is practically possible to send mail to Pratas Island (Tungsha/Dongsha) (817) and Taiping Island, the largest island of the Spratly Islands (819), as those are above sea level and controlled by Taiwan. There is no mail delivery to the Diaoyutai Islands (290), as they are controlled by Japan and have been uninhabited for many decades.
