What is the Ireland country code?

Everything you need to dial a Ireland number correctly from a UK phone.

+353

The Ireland country code is +353. Dialling from the UK? Use 00353 instead of the + — they do exactly the same thing.

How to dial a Ireland number from the UK

Dial 00353 + area code + local number for landlines, dropping the leading zero. Mobiles start with 08 — dial 00353 8 + the remaining digits.

Example: Dublin landline: 00353 1 + 7-digit number. Mobile starting 087: dial 00353 87 + remaining digits.

00 or +? Either works

Typing +353 (hold the 0 key on most phone keypads to get a +) is the international standard and works automatically wherever you're calling from. 00353 is the UK's own way of dialling out internationally — both reach exactly the same number.
