Format guide
Kaohsiung · 3+3 postal code format
Samples on this page lock the city/county field to 高雄市 (Kaohsiung). District/township is drawn from that city's table, the first three postal digits stay bound to the district, and +886 phones use the matching area code. English lines use No./Sec./Ln./Aly. with romanized road names.
Postal codes
Kaohsiung follows Taiwan's 3+3 postal pattern: first 3 digits = admin district, full code is 6 digits (e.g. 100xxx / 220 / 406 / 300). Samples are fictional format tests—not an official Chunghwa Post endorsement.
Typical use cases
Kaohsiung samples are fictional and meant for layout checks, validation rules, and format learning. Do not use them for checkout, identity verification, shipping labels, or to work around regional restrictions.
How to use test data
In development you can use these samples to check field length, line breaks, international characters, and responsive layouts. For payment, identity, logistics, or compliance flows, use official sandbox data from your provider—do not submit these samples to live systems.
