Taiwan phone number format
How do you format a Taiwan phone number?
Write a Taiwan phone number with the country code +886. A mobile looks like 0912 345 678 inside Taiwan and +886 912 345 678 from abroad, dropping the leading 0. Mobiles have 9 digits after the country code, and the E.164 form is +886912345678. Format alone never shows a line is in service.
Free, runs in your browser; nothing is sent. The sample is a sample, not a real line.
Paste your Taiwan numbers (a mixed list is fine). They are counted here at once; the free checker then gives every number its E.164 form, country and line type, with a file to download.

| Country calling code | +886 |

| Trunk prefix (domestic dialling) | 0 |
| Mobile number length | 9 digits after +886 |
| Landline number length | 8 or 9 digits after +886 |
| Mobile vs landline from the digits | Yes, separate ranges |
In short: +886, 9 digits for a mobile, drop the leading 0 after +886. The checker below formats any Taiwan number free in your browser; it can't say whether a line is live. Bulk phone number validator · Pro + Phone plan

| Format | Mobile | Landline |
|---|---|---|
| National (inside Taiwan) | 0912 345 678 | 02 2123 4567 |
| International | +886 912 345 678 | +886 2 2123 4567 |
| E.164 | +886912345678 | +886221234567 |
How to write a Taiwan number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside Taiwan.
- Put +886 in front. The result has 9 digits after the country code for a mobile.
So 0912 345 678 becomes +886912345678. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Taiwan allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.
Mobile, landline and special number ranges in Taiwan
A Taiwan mobile number starts with 4000, 90–98 after +886. Every valid number of each type below starts with one of the digit groups shown. A number that starts the right way can still be unassigned: the groups say what a range is for, not that a number is connected.
| Type | Starts with, after +886 | Dialled inside Taiwan | Digits | Example |
|---|---|---|---|---|
| Mobile | 4000, 90–98 | 04000, 090–098 | 9 | +886 912 345 678 |
| Landline (fixed line) | 22–28, 32–39, 40–44, 47–49, 52–58, 60–67, 69, 71–79, 82–84, 87–89 | 022–028, 032–039, 040–044, 047–049, 052–058, 060–067, 069, 071–079, 082–084, 087–089 | 8 or 9 | +886 2 2123 4567 |

Common questions
- What is the country code for Taiwan?
- The country calling code for Taiwan is +886. When you call Taiwan from abroad, dial your international prefix (or +) followed by 886 and the number without its leading 0.
- How many digits is a Taiwan phone number?
- A Taiwan mobile number has 9 digits after the country code +886, and a landline has 8 or 9. Written for dialling inside Taiwan, a number gains the trunk prefix 0 in front.
- How do I write a Taiwan number in international format?
- Start with +886, drop the leading 0, then add the rest of the number. The mobile number 0912 345 678 becomes +886 912 345 678, or +886912345678 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Taiwan number is a mobile?
- Usually, yes. Taiwan numbers come from ranges allocated separately to mobiles and landlines, so a numbering-plan check reads the line type from the digits. It tells you what the range is for, not whether the number is in service.
- Does a valid format mean a Taiwan number is in service?
- No. A valid format means the digits fit a range Taiwan's numbering plan allocates. It cannot tell whether the number is connected today or who carries it, because numbers are reassigned and ported. A live carrier lookup reports the current carrier and line type, but even that does not prove someone answers.
- Can I check a list of Taiwan numbers for free?
- Yes. Paste them in the list tab above or upload a CSV to the bulk phone number validator: E.164, country, format status and numbering-plan line type are free for every row, with no account. Live carrier and line-type lookups come with Pro + Phone at $49.99/mo (5,000 a month).
