The Ireland phone code you need to look up is +353. When calling Ireland from abroad, you should follow a standard format.
Dialing Format: International Exit Code + 353 + Irish Local Number (remove the ‘0’ at the beginning of the number)
If you are using a smartphone, you can directly use the “+” sign instead of your country’s international exit code. This method makes the dialing process very simple.

To successfully connect a call, you need to clearly understand each component of the dialing format. It’s like a puzzle where every piece must be in the right place. We will break down the dialing process into three simple steps.
Before dialing any international number, you need to enter a special code known as the “international exit code” or “international dial-out code”. This code tells your phone network that the next number you dial is an international call, not a local one.
The international exit code may differ for each country or region. For example:
📱 Smartphone Tip To simplify the process, modern smartphones offer a universal solution. Simply long-press the “0” key on the dial pad, and a “+” sign will appear on the screen. This “+” sign can automatically replace all international exit codes for the country you are in. No matter where you are, using the “+” sign is the simplest and least error-prone way to make international calls.
After entering the international exit code (or “+” sign), the next step is to enter Ireland’s country code. This code is globally unique and identifies the country you are calling.
Ireland’s country code is 353.
This three-digit code is the bridge connecting you to Ireland. So, your dialing sequence now looks like this: International Exit Code + 353 or +353.
This is the most critical and error-prone step in the entire dialing process. Irish local phone numbers, whether landline or mobile, usually start with “0” when dialed domestically in Ireland. But when making an international call,you must remove this leading “0”.
Why? Because this “0” is a domestic trunk prefix used in Ireland for long-distance calls. When you have already used an international exit code (such as “00” or “+”), this domestic trunk prefix becomes redundant. Keeping it will confuse the phone system and cause the call to fail.
Landline (Fixed) Numbers
Irish landline numbers include an area code. For example, Dublin’s area code is 01. When calling from abroad, you need to remove the 0 and dial only 1.
Here are the area codes (domestic format) for some major regions in Ireland:
| Region Name | Area Code |
|---|---|
| Dublin | (0)1 |
| Cork | (0)21 |
| Galway | (0)91 |
| Limerick | (0)61 |
| Waterford | (0)51 |
| Dundalk | (0)42 |
| Sligo | (0)71 |
| Kilkenny | (0)56 |
Mobile Numbers
The same rule applies to mobile numbers. Irish mobile numbers typically start with 08 when dialed domestically (such as 083, 085, 086, 087, 089).
08X-XXX-XXXX.0 and dial directly 8X-XXX-XXXX.Remember this simple rule, and you can correctly use the Ireland phone code to successfully connect your call.
You have mastered the theory; now let’s look at how to call Ireland from different countries through some specific examples. Try it once in practice, and you’ll find the entire process very simple.
If you are in mainland China, you need to dial the international exit code 00 first.

To avoid having to look up and enter complex codes every time you make an international call, we strongly recommend adopting a once-and-for-all storage method.
Best Practice No matter where you are, save Irish contacts’ numbers in your phone’s address book in the full international format. This format starts with the “+” sign, followed by the country code and the local number without the “0”.
- Landline Example:
+353 1 234 5678(Dublin number)- Mobile Number Example:
+353 87 123 4567
Why do this?
Developing this good habit will save you a lot of time and effort, especially when you need to make frequent international calls.
