Calling Ireland from abroad with a local Irish caller ID
People in Ireland are as quick as anyone to ignore a number they do not recognise. What a local +353 number does for you, the Irish rules on marketing calls, and when to call.
Ireland looks like a natural add-on for any team already calling the UK: the same language, the same time zone and many of the same companies. The one thing that does not carry over is the caller ID. A UK +44 number ringing an Irish mobile shows up as an international call, and people in Ireland are as quick as anyone to let an unknown foreign number ring out.
Why an Irish number matters
An Irish +353 number tells the person you are calling that the call is local, and that calling back will not cost them international rates. That is the whole effect, and it is a large one. The same reasoning is behind why a local number gets answered in any country.
Use a genuine Irish number. ComReg, the Irish communications regulator, has pushed networks to block calls showing invalid or misused Irish numbers as part of its work against scam calls, so an invented or borrowed number is more likely to be blocked than answered.
Irish numbers at a glance
The country code is +353. Drop the leading 0 of an Irish number when you dial it with the code.
Mobile numbers start with 08, such as 083, 085, 086, 087 and 089.
Landlines start with an area code: 01 for Dublin, 021 for Cork, 061 for Limerick and 091 for Galway.
Clean your list into one format, +353 followed by the number without the 0, so duplicates are easy to spot.
Rules for marketing calls in Ireland
Ireland's rules on marketing calls come from its ePrivacy Regulations, which the Data Protection Commission enforces, and they differ from the UK's in ways that matter. This is a plain summary, not legal advice.
Landlines: do not make marketing calls to a number whose owner has opted out on the National Directory Database (NDD), or who has told you they do not want your calls.
Mobiles: marketing calls to an individual's mobile number generally need that person's prior consent. Treat personal Irish mobiles on a cold list as off limits until you can show consent.
Say who you are and who you are calling for, and give contact details if asked.
Keep your own suppression list and honour opt-outs straight away.
For cold outreach, business landlines are usually the safer place to start.
When to call
Ireland keeps the same clock as the UK all year and changes it on the same dates. For a team in Pakistan, Irish office hours of 9am to 5:30pm fall between 1pm and 9:30pm in the Irish summer and between 2pm and 10:30pm in winter. Our calling hours guide has the table for other countries.
Calling the UK and Ireland from one floor
Many teams call both countries. The simplest setup splits the work: agents with a UK number work the UK list, and agents with an Irish number work the Irish list, so every call shows a local caller ID. Keep the two lists apart as well, because the rules for each country differ.
Setting it up on ReachCalls
ReachCalls has UK and Ireland plans for one dialer or for a team. UK-only plans do not dial Ireland, so choose a UK + Ireland plan if you call both. Agents call from a browser tab with a local caller ID, the admin chooses which number each agent calls from, and you pay by local bank transfer with no processing fee. The pricing page lists the plans.
Questions people ask
Can I call Ireland with a UK number?
You can, but an Irish phone shows a UK +44 number as an international call, which many people will not answer. A local Irish +353 caller ID looks like a local business and costs the person nothing extra to call back.
Is Ireland in the same time zone as the UK?
Yes. Ireland and the UK keep the same clock all year and change it on the same dates.
Can I cold call Irish mobile numbers?
Marketing calls to an individual's Irish mobile number generally need their prior consent, so a cold list of personal mobiles is risky. Business landlines are the safer place to start. This is not legal advice.
