Bulgaria phone number format
How do you format a Bulgaria phone number?
Write a Bulgaria phone number with the country code +359. A mobile looks like 043 012 345 inside Bulgaria and +359 43 012 345 from abroad, dropping the leading 0. Mobiles have 8 or 9 digits after the country code, and the E.164 form is +35943012345. 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 Bulgaria 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.

| Format | Mobile | Landline |

| National (inside Bulgaria) | 043 012 345 | 02 123 456 |
| International | +359 43 012 345 | +359 2 123 456 |

How to write a Bulgaria 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 Bulgaria.
- Put +359 in front. The result has 8 or 9 digits after the country code for a mobile.
So 043 012 345 becomes +35943012345. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Bulgaria 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 Bulgaria
A Bulgaria mobile number starts with 430, 437–439, 87–89, 98, 996, 999 after +359. 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.

| Mobile | 430, 437–439, 87–89, 98, 996, 999 | 0430, 0437–0439, 087–089, 098, 0996, 0999 | 8 or 9 | +359 43 012 345 |

Common questions
- What is the country code for Bulgaria?
- The country calling code for Bulgaria is +359. When you call Bulgaria from abroad, dial your international prefix (or +) followed by 359 and the number without its leading 0.
- How many digits is a Bulgaria phone number?
- A Bulgaria mobile number has 8 or 9 digits after the country code +359, and a landline has 6 to 8. Written for dialling inside Bulgaria, a number gains the trunk prefix 0 in front.
- How do I write a Bulgaria number in international format?
- Start with +359, drop the leading 0, then add the rest of the number. The mobile number 043 012 345 becomes +359 43 012 345, or +35943012345 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Bulgaria number is a mobile?
- Usually, yes. Bulgaria 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 Bulgaria number is in service?
- No. A valid format means the digits fit a range Bulgaria'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).
