Taiwan ZIP Code Guide
Instant lookup for Taiwan 3 digit and 3+3 digit ZIP codes
Tap the image to open the tool ↗Shipping forms and checkout pages keep asking for a ZIP code, and the six digit 3+3 format in particular leaves people unsure how many digits to write and where. This page introduces the tools on the ZIP code site, then brings together how Taiwan's codes are arranged, how to write them on an envelope and in an English address, and the mistakes that come up most.
The ZIP code site is in Traditional Chinese. Its address translator is the part most useful to English speakers, since it turns a Chinese address into the official English version.

What is on the ZIP code site
- Address lookup: type a full address (city, district, road and house number) to get the 3 digit and 3+3 digit codes. Both the 台 and 臺 spellings work.
- ZIP code directory: 3 digit codes for all 22 cities and counties and 368 townships and districts, with road and house number ranges and their 3+3 codes on each district page.
- Address translator: converts a Chinese address into the English address using Chunghwa Post's official romanisation, with the 3+3 code included, ready to paste into a foreign form or a parcel label.
- Mailing guides: articles on envelopes, mail services, international parcels and address translation, listed below.
The data comes only from files published by Chunghwa Post. If a result differs from Chunghwa Post's own lookup, Chunghwa Post is the authority.
3 digit, 3+3 digit and the retired 3+2 format
- 3 digits: the township or district. Enough for ordinary mail.
- 3+3 digits (6 digits): the current format, in use since March 2020. The first three digits are still the district, and the last three identify a delivery segment as specific as a range of house numbers on one road.
- 3+2 digits (5 digits): the old format, no longer in service.
A 3+3 code is not the old 5 digit code with a digit added. The first three digits match, but the old two digit ending and the new three digit ending were planned separately, cannot be swapped, and one cannot be derived from the other. When a form asks for six digits, look up the 3+3 code for that address rather than padding an old code.
How the first three digits are arranged
The first three digits map to a district, numbered roughly from north to south. Taipei starts at 1xx. Keelung, New Taipei and Yilan are 2xx. Going south, Taoyuan, Hsinchu and Miaoli are 3xx, Taichung 4xx, Changhua and Nantou 5xx, Yunlin and Chiayi 6xx, Tainan 7xx, Kaohsiung 8xx, and Pingtung, Hualien and Taitung are 9xx. The first three digits alone tell you roughly where in Taiwan an address is.
Where the code goes on an envelope
- Vertical Chinese envelope: written top to bottom, right to left, with the recipient's code in the red boxes at the top right.
- Horizontal Chinese envelope: written left to right, with the recipient's code in the red boxes in front of the address.
- Online orders and courier forms: there is usually a separate ZIP code field. Put the code there.
Chinese addresses run from large to small: city, district, road and section, lane and alley, number and floor. The envelope guide (in Chinese) has diagrams showing where the stamp and sender go.
Two rules for English addresses
- Reverse the order, from small to large: floor, number, lane and alley, road and section, district, city, then the ZIP code and the country. For example: 3F., No. 122, Sec. 1, Chongqing S. Rd., Zhongzheng Dist., Taipei City 100407, Taiwan (R.O.C.).
- Use the official road names: Chunghwa Post uses Hanyu Pinyin, and a few roads have special names, such as Roosevelt Rd.
The address translator does this for you, and the address translation guide explains abbreviations such as No., Ln., Sec. and Dist.
Where addresses go wrong
- District changes: after a merger or a boundary adjustment, the old code may no longer apply. Work from current data.
- Repeated road names: almost every city has a Zhongshan Road and a Zhongzheng Road. Confirm the city and district along with the road.
- Same road, different numbers: 3+3 codes go down to house number ranges, so different numbers on the same road can have different last three digits.
- New developments: house numbers in newly developed areas are recent. If nothing comes up, check the house number first.

Questions people ask
How often is the data updated? The site uses the official files published by Chunghwa Post and follows their releases. Very recent house number or road changes may not show up yet, so for important mail, Chunghwa Post's own lookup is the final word.
Do I have to include a ZIP code? A correct code speeds up sorting and reduces delays. Mail without one usually still arrives, just more slowly.
Does the code always have to be six digits? It depends on the form. You can write the 3 digit code or the more precise 3+3 code. When a field asks for six digits, look up the 3+3 code for that address.
Why can I not find the 6 digit code for an address? Usually the house number has a typo, the address is incomplete, or the house number is new. Check the city, district, road and number and try again, or use the 3 digit code.
