Ireland phone number format

Ireland phone numbers use the country code +353. A mobile number looks like 085 012 3456 inside Ireland and +353 85 012 3456 from abroad: the leading 0 is dropped after +353. Mobiles have 9 digits after the country code, and the E.164 form is +353850123456.

How to write a Ireland number in E.164

  1. Remove spaces, dashes, dots and brackets so only digits are left.
  2. If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside Ireland.
  3. 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.

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.
