How to use Taiwan's 3+3 postal codes

Taiwan uses a six-digit 3+3 postal code. The first three digits identify the administrative district; the final three identify a delivery section or special delivery number. The city and county pages here organize district-level prefixes such as 700 so you can find the right area quickly. A three-digit prefix alone is not a complete delivery code.

For a complete six-digit code, check the entire street address, including the city or county, district, road, lane, number and any other relevant details. The map places offshore islands in separate inset boxes so the main island remains large and readable; those boxes do not show true distances. Confirm the final code with Chunghwa Post when preparing mail.

Start with the map or city and county list, then open the relevant local page to compare district names and three-digit prefixes. A prefix such as 700 identifies an area in the directory; its detail page lists the associated districts and six-digit delivery codes. Do not treat a matching prefix as confirmation of the final three digits for a specific delivery address.

When two addresses are in the same district, their complete 3+3 codes can still depend on delivery details. Check the road or street, section, lane, alley, house number and other address elements as applicable. PostalMap is useful for finding the city, county and district context quickly, while Chunghwa Post's official search should be used to confirm the final six-digit code before mailing.
