What's the country calling code for Ireland?

Need to call someone in Dublin, Cork, or Galway? While the UK and Ireland are close neighbours, calls to Irish numbers are considered international. That means you have to use the full country code sequence to connect.

This guide is designed to clear up any confusion. We explain the international code for Ireland (+353), walk you through the exact dialling steps for both landlines and mobiles, and share tips on saving money and avoiding common mistakes, whether you’re calling from home or using a Revolut eSIM while travelling.

Understanding the international code for Ireland

Making an international call requires a specific, multi-step sequence. The full sequence is essential to direct your call and ensure a successful connection.

The role of the international access code (00 or +)

Your call must begin with an international access code, also known as an exit code. This tells your phone company that the next digits are for a country outside of your own.

• Calling from a mobile phone: you should always start your sequence with +. This allows your phone company to redirect your call out of your country. Since most customers use mobile phones, this makes things simpler.
• Calling from a landline: you must start with 00 instead of +. This is the standard international exit code for the UK and many other countries.

The mandatory Irish country code: 353

Immediately following your exit code, you must dial the country code. In this case, you use the Ireland dialling code, 353.

Whether you begin with the landline exit code or the mobile + symbol, the combined sequence is the international dialling code for Ireland.

• Mobile full start: +353

Example: if the Irish mobile number is 087 987 6543, you'd dial +353 87 987 6543.

• Landline full start: 00 353

Example: if the Irish number is 01 401 2345, you'd dial 00 353 1 401 2345.

Understanding this format is the first step in mastering the correct Irish phone number format.

How to call an Irish phone number from the UK

Once you've entered the country code, the rest of the sequence is easy — you just need to dial the Irish phone number. But there’s one important thing to remember: Irish phone numbers usually start with a 0 when you're calling from within Ireland. But if you're calling from the UK or any other country, you don’t use this 0. You leave it out and just dial the rest of the number. When calling internationally, the country code replaces it.

The general format you need to follow is:

• UK exit code or +
• Ireland country code: 353
• Full Irish phone number (without the initial 0)

Dialling Irish mobile numbers

Irish mobile numbers are typically 10 digits long (including the initial 0) and usually start with 08.

Example: 087 987 6543.

However, as mentioned above, you need to drop the 0 and replace it with +353 when you're calling from the UK.

Example: +353 87 987 6543.

Dialling Irish landlines: regional area codes explained

Irish landline numbers typically include a one, 2, or 3-digit area code, followed by a local number.

For example, if your contact in Dublin provides the landline number 01 401 2345, the international dialling code would be +353 1 401 2345.

How to save your Irish contacts

For seamless calling and messaging, especially when you're travelling or using apps, you should always save your Irish contacts in the international format.

Always save the contact starting with the + symbol and the country code.

• Correct mobile save: +353 87 987 6543
• Correct landline save: +353 1 401 2345

This standard format ensures that apps and services correctly interpret the number, removing any need to manually adjust the format or exit code, regardless of your current location.

Why didn't my call to Ireland work?

Common dialling mistakes

If you tried to call an Irish contact and your call failed, you've most likely made a common dialling mistake. Even with the Irish country code entered correctly, other small mistakes in the sequence can stop your call from going to plan.

Mistake 1: forgetting to drop the domestic 0

This is the most common error for international calls to Ireland. The domestic trunk code, 0, is only used for local calls within Ireland. When you dial the country code, it should replace the 0, so make sure you're not leaving it in.

Mistake 2: calling Northern Ireland with the wrong code

Northern Ireland is part of the UK and uses the +44 country code, not the +353 code. Dialling a Belfast number using +353 won't fail.

Mistake 3: the hidden costs of international calling

Despite the short distance, calls between Ireland and the UK are still considered international. If you're using a standard UK phone plan, calling Ireland ‌can incur significant per-minute charges.

Make sure you check your network provider's specific international calling rates to Ireland before you dial. This is especially important if you're travelling to Ireland from the UK. Relying on UK network roaming for calls and data in Ireland can be expensive, which leads many customers to seek alternatives. Our Ireland eSIM data plan offers a digital solution, allowing you to instantly buy data plans in-app and bypass those costly traditional roaming fees.

Other Irish phone number types (toll-free and premium)

It's useful to know about 2 other types of Irish numbers you might encounter:

• Freephone (1800): these numbers are primarily for business use within Ireland and are free to call from Irish landlines. However, calling them internationally using the international dialling code for Ireland will likely incur charges or lead to connection issues.
• Non-geographic (e.g. 076 or 0818): these numbers are often used by businesses and institutions for national access. You must drop the initial 0 when dialling from outside Ireland (e.g. +353 76 or +353 818).

Frequently asked questions (FAQs)

What's the difference between +353 and 00353?

Both +353 and 00353 represent the country code of Ireland. The difference is in how you dial them: 00 is the international exit code specifically for a UK landline, while the + symbol is the universal international access code for mobiles. Always use +353 on a mobile phone.

Can I text an Irish phone number using +353?

Absolutely. Text messaging follows the same format as voice calls. You must begin the number with +353 and ensure the domestic 0 is dropped from the Irish mobile number (e.g. +353 87 987 6543).

What about calling Northern Ireland?

Northern Ireland is part of the UK and uses the +44, not +353. Always use +44 followed by the 9-digit number for calls to Northern Ireland.
