Calling Ireland from the UK is something many businesses and individuals need to do regularly. Whether you are phoning a supplier in Dublin, a branch office in Cork, or a client in Galway, the process is quick once you know the correct dialling format.
Ireland and the UK are close neighbours, but calls between the two countries are still classed as international. Standard UK phone plans do not typically include Irish calls in their allowance, which means per-minute charges apply unless you use an alternative like VoIP.
What Is the Dialling Code for Ireland from the UK?
The country code for the Republic of Ireland is 353. To call Ireland from the UK, you dial the UK exit code followed by 353, then the Irish phone number without the leading 0.
From a UK Landline
Dial 00 (the UK international exit code), then 353 (Ireland's country code), then the Irish number without the first 0.

Example for a Dublin landline (01 234 5678): 00 353 1 234 5678
From a UK Mobile
Replace 00 with the + symbol. Dial +353 followed by the number without the leading 0.
Example for an Irish mobile (087 123 4567): +353 87 123 4567

The most common mistake is leaving the leading 0 in the Irish number. When you dial the country code, it replaces the 0. Including both will cause the call to fail.
Ireland vs Northern Ireland: Which Code to Use
Northern Ireland is part of the United Kingdom and uses the UK country code +44, not the Irish code +353. Calling a Belfast number with +353 will not connect.
| Destination | Country Code | Example |
|---|---|---|
| Republic of Ireland (Dublin, Cork, Galway) | +353 | +353 1 234 5678 |
| Northern Ireland (Belfast, Derry) | +44 | +44 28 9012 3456 |
If your business deals with contacts on both sides of the border, save all numbers in international format (+353 or +44) so they dial correctly regardless of where you are calling from.
Area Codes for Major Cities in Ireland
Irish landline numbers consist of a one to three-digit area code followed by a local number. The total length of an Irish phone number is typically seven to nine digits (including the area code). Mobile numbers are 10 digits long and start with 08.
| City / Region | Area Code (Domestic) | Area Code (International) |
|---|---|---|
| Dublin | 01 | 1 |
| Cork | 021 | 21 |
| Galway | 091 | 91 |
| Limerick | 061 | 61 |
| Waterford | 051 | 51 |
| Dundalk | 042 | 42 |
| Drogheda | 041 | 41 |
| Sligo | 071 | 71 |
| Kilkenny | 056 | 56 |
| Donegal | 074 | 74 |
When calling internationally, always use the "international" column and drop the leading 0 from the domestic code.
How Much Does It Cost to Call Ireland from the UK?
Despite the short distance, calls to Ireland from the UK are international calls and are priced accordingly.
From a standard UK mobile contract, calls to Irish numbers typically cost between 30p and £1.50 per minute. Some business mobile plans include EU or Ireland calling, so it is worth checking your tariff.
From a UK landline, rates vary by provider but generally fall between 10p and 50p per minute. Peak hours (daytime) are usually more expensive than off-peak (evenings and weekends).
For businesses that call Ireland frequently, a VoIP phone system removes the per-minute cost problem entirely. VoIP routes calls over the internet, and many plans include Ireland as part of a bundled international calling allowance.
How to Call Ireland Cheaper Using VoIP
VoIP (Voice over Internet Protocol) sends calls over your internet connection instead of through the traditional phone network. For UK businesses with Irish clients, suppliers, or team members, VoIP is the most practical way to keep call costs low.
A cloud phone system lets your team call Ireland from desk phones, laptops, or smartphones using a softphone app. Calls route through the internet, so the rate stays the same whether someone is in the office or working remotely. Many VoIP plans include calls to Irish landlines and mobiles within the monthly price.
VoIP calling apps on your mobile or desktop provide another route. The app uses broadband or mobile data to place the call, bypassing your mobile network's international rates.
Time Zone and Best Time to Call Ireland
Ireland is on the same time zone as the UK throughout the year. Both countries follow Greenwich Mean Time (GMT) in winter and move to British Summer Time / Irish Standard Time (BST/IST) in summer.
No time zone adjustment is needed when scheduling calls between the UK and Ireland. Standard business hours (9:00 am to 5:30 pm) align exactly.
Tips for Calling Ireland from the UK
A few points to keep in mind:
- Always drop the leading 0 from the Irish number when dialling internationally. The country code replaces it.
- Save Irish contacts in +353 format. Your phone will then connect correctly from any location.
- Check your plan before calling. Many UK contracts treat Ireland as a standard international destination with per-minute charges.
- Freephone numbers (1800) in Ireland are free to call within Ireland only. Calling them from the UK may incur charges or fail to connect.
- Text messages to Irish mobile numbers follow the same +353 format. Standard international SMS rates apply.
