Ireland phone number format
How do you format a Ireland phone number?
Write a Ireland phone number with the country code +353. A mobile looks like 085 012 3456 inside Ireland and +353 85 012 3456 from abroad, dropping the leading 0. Mobiles have 9 digits after the country code, and the E.164 form is +353850123456. 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 Ireland 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.

Example Ireland phone numbers
These are the example numbers from Google’s libphonenumber data, the same numbering-plan data our validator uses, written three ways.
| Format | Mobile | Landline |
|---|---|---|
| National (inside Ireland) | 085 012 3456 | (022) 12345 |
| International | +353 85 012 3456 | +353 22 12345 |
| E.164 | +353850123456 | +3532212345 |
How to write a Ireland 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 Ireland.
- Put +353 in front. The result has 9 digits after the country code for a mobile.
So 085 012 3456 becomes +353850123456. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Ireland 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 Ireland
A Ireland mobile number starts with 822, 83, 85–89 after +353. 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 Ireland?
- The country calling code for Ireland is +353. When you call Ireland from abroad, dial your international prefix (or +) followed by 353 and the number without its leading 0.
- How many digits is a Ireland phone number?
- A Ireland mobile number has 9 digits after the country code +353, and a landline has 7 to 10. Written for dialling inside Ireland, a number gains the trunk prefix 0 in front.
- How do I write a Ireland number in international format?
- Start with +353, drop the leading 0, then add the rest of the number. The mobile number 085 012 3456 becomes +353 85 012 3456, or +353850123456 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Ireland number is a mobile?
- Usually, yes. Ireland 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 Ireland number is in service?
- No. A valid format means the digits fit a range Ireland'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 Ireland 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).
