Postal codes in Taiwan


Postal codes in Taiwan is a system of three + two digits used by Chunghwa Post. There are 368 sets of three-digit codes for townships, county-controlled cities, and districts in Taiwan.
The cities of Chiayi and Hsinchu have a single code covering all their districts. The uninhabited islands Pratas and Spratly each have a single code. The uninhabited Senkaku Islands have a code, but there are no deliveries.
Omitting the supplementary two digits is ordinarily acceptable, but using a five-digit code will speed the delivery of the mail.
