Kazakhstan phone number format
How do you format a Kazakhstan phone number?
Write a Kazakhstan phone number with the country code +7. A mobile looks like 8 (771) 000 9998 inside Kazakhstan and +7 771 000 9998 from abroad, dropping the leading 8. Mobiles have 10 digits after the country code, and the E.164 form is +77710009998. 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 Kazakhstan 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.

| International | +7 771 000 9998 | +7 71234 5 67 89 |

How to write a Kazakhstan number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- If the number starts with the trunk prefix 8, remove it. It is only used when dialling inside Kazakhstan.
- Put +7 in front. The result has 10 digits after the country code for a mobile.
So 8 (771) 000 9998 becomes +77710009998. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Kazakhstan 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 Kazakhstan
A Kazakhstan mobile number starts with 700–702, 705–708, 747, 760–764, 771, 775–778, 785 after +7. 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.

Common questions
- What is the country code for Kazakhstan?
- The country calling code for Kazakhstan is +7. It is shared with 1 other country or territory, so the number after it decides which one a number belongs to. When you call Kazakhstan from abroad, dial your international prefix (or +) followed by 7 and the number without its leading 8.
- How many digits is a Kazakhstan phone number?
- A Kazakhstan mobile number has 10 digits after the country code +7, the same as a landline. Written for dialling inside Kazakhstan, a number gains the trunk prefix 8 in front.
- How do I write a Kazakhstan number in international format?
- Start with +7, drop the leading 8, then add the rest of the number. The mobile number 8 (771) 000 9998 becomes +7 771 000 9998, or +77710009998 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Kazakhstan number is a mobile?
- Usually, yes. Kazakhstan 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 Kazakhstan number is in service?
- No. A valid format means the digits fit a range Kazakhstan'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.
