Mongolia phone number format
How do you format a Mongolia phone number?
Write a Mongolia phone number with the country code +976. A mobile looks like 8812 3456 inside Mongolia and +976 8812 3456 from abroad. Mobiles have 8 digits after the country code, and the E.164 form is +97688123456. A format check confirms the digits fit the numbering plan, not that the number is in service.
Free, runs in your browser; nothing is sent. The sample is a sample, not a real line.
Paste your Mongolia 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.

How to write a Mongolia number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- Mongolia has no trunk prefix, so keep every digit of the national number.
- Put +976 in front. The result has 8 digits after the country code for a mobile.
So 8812 3456 becomes +97688123456. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Mongolia 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 Mongolia
A Mongolia mobile number starts with 50, 55, 60, 66, 69, 72, 78, 80, 81, 83, 85–89, 9 after +976. 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 +976 | Digits | Example |
|---|---|---|---|
| Mobile | 50, 55, 60, 66, 69, 72, 78, 80, 81, 83, 85–89, 9 | 8 | +976 8812 3456 |
| Landline (fixed line) | 11–15, 21–26, 53, 56, 58, 70, 71 | 8 to 10 | +976 5312 3456 |
| VoIP | 710, 711, 7120–7127, 7129, 713–719, 75–77, 79 | 8 | +976 7512 3456 |

Common questions
- What is the country code for Mongolia?
- The country calling code for Mongolia is +976. When you call Mongolia from abroad, dial your international prefix (or +) followed by 976 and the number.
- How many digits is a Mongolia phone number?
- A Mongolia mobile number has 8 digits after the country code +976, and a landline has 8 to 10.
- How do I write a Mongolia number in international format?
- Start with +976, then add the rest of the number. The mobile number 8812 3456 becomes +976 8812 3456, or +97688123456 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Mongolia number is a mobile?
- Usually, yes. Mongolia 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 Mongolia number is in service?
- No. A valid format means the digits fit a range Mongolia'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.

- 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).
