Taiwan ZIP Code Lookup
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 since Taiwan moved to six digits most people have no idea what theirs is. This page turns an address into the current 3+3 code and explains how the system works, how to write it on an envelope, and where addresses commonly go wrong.

What this tool does
Type in a full address and the tool resolves the matching 3 digit code for the district and the current 3+3 digit (6 digit) code as you type. The data comes from official Chunghwa Post sources, and the reference tables go down to road and house number ranges, which is more precise than tools that stop at the district. The retired 5 digit format (3+2) is out of service and is not offered here.
What you get:
- Live address parsing: enter an address and both the 3 digit and 3+3 digit codes appear.
- City and district pages: browse complete ZIP code listings by city and district.
- Street level tables: each district lists roads and house number ranges with their 3+3 codes.
- Mailing guide: where the code goes on an envelope and how to write the address.
What changed between 3+2 and 3+3
- 3+2 (5 digits): the old format. The first three digits were the district and the last two were the delivery segment of the time. It has been replaced by the 3+3 format and is no longer in service.
- 3+3 (6 digits): the current format, in use since 3 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, which speeds up sorting and delivery.
The 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 are not interchangeable and one cannot be derived from the other. When a form asks for a code, look up the current 3 digit and 3+3 digit values here and fill in whichever the form wants.
How the first three digits are arranged
The first three digits map to a district, and the numbering runs 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 along with Hualien and Taitung are 9xx. The first three digits alone tell you roughly where in Taiwan an address is. The last three digits of a 3+3 code are the finer delivery segment inside that district.
Writing the code on mail
- Vertical envelope: the recipient's ZIP code goes in the red boxes in the top right corner.
- Horizontal envelope: the recipient's ZIP code goes on the first line, above the address.
- Online orders and couriers: there is usually a separate ZIP code field next to city, district and street address. Put the code you looked up there.
Taiwanese addresses run from large to small: city, district, road or street, section, lane, alley, number, floor. The ZIP code stands for the city and district part, plus the delivery segment, so getting it right helps mail reach the correct route faster.
Writing an address in English
In English the order is reversed, from small to large: number, alley and lane, road, district, city, ZIP code, then Taiwan (R.O.C.). For example:
No. 7, Sec. 1, ○○ Rd., ○○ Dist., Taipei City 100, Taiwan (R.O.C.)
The ZIP code usually follows the city name. When you need the official romanisation of a road name, the Chunghwa Post Chinese address translation service is the reference to check against.
Where addresses go wrong
- District changes: after a merger or a boundary adjustment, the old code may no longer apply. Always work from current data.
- Repeated road names: almost every city has a Zhongshan Road and a Zhongzheng Road. Confirm the city and district together with the road, or you will end up with the code for a different area.
- New buildings and redevelopment areas: house numbers and 3+3 codes in newly developed areas are recent. If nothing comes up, check that the house number is correct first.
How to use it
- Enter the full address in the search box, including city, district, road and house number.
- The matching 3 digit and 3+3 digit codes appear immediately.
- You can also browse the tables for a whole district from the city and district pages.
Questions people ask
How often is the data updated? It follows the official data published by Chunghwa Post, so lookups return the current codes.
Do I have to include a ZIP code? A correct code speeds up sorting and delivery, and the 3+3 code in particular routes mail to the right delivery segment sooner. Mail without one usually still arrives, just more slowly.
Does the code always have to be six digits? It depends on the form or the system you are filling in. You can write the 3 digit code or the more precise 3+3 digit code. When a field asks for six digits, look up the 3+3 code for that address here. Do not pad an old 5 digit code with an extra digit, because the endings of the two formats are not interchangeable.
Why can I not find the 6 digit code for an address? Usually the house number has a typo, the road section is new, or the address is incomplete. Check the city, district, road and number and try again.
