Phone Numbers, Phone Codes and Telephone Directories in Ireland
To find a phone number in Ireland, first decide whether the number is in Eire (the Irish Republic) or Northern Ireland, as the phone books and dialling codes are different. The Ireland (Eire) telephone country code is 353, but Northern Ireland is regarded as part of the UK, so its phone country code is 44 with an area code of 28. In both Irelands, you don’t need the telephone area code if you’re dialling within the area, e.g. Dublin, itself.
When calling an Irish phone number from outside the country, you must omit the “0” from the beginning of the area code. From the Irish Republic you can dial 048 for Northern Ireland landline access (may also be dialed as an international call to the UK using 004428 ). You have to dial the complete number for mobile (cell) phones in Ireland, but miss off the preceding “0” if you’re calling from abroad.

https://www.eirphonebook.ie/q/name/: Eir operates the largest fixed-line telecommunications network in the Republic of Ireland, under licence from the Commission for Communications Regulation (ComReg). Most homes and businesses in the state are dependent on their network. They appear to have outsourced their directory services to FCR Media. They have a business and residential search.
N.B. I could not access their site from Australia as Amazon geoblocked it, and had to use a VPN (I used a UK server).
http://www.118.ie/: 11850 Irish business search and people search white pages. It’s was free online, but now they seem to have taken away the online search and you have to phone them up (costs money if you do it by phone!).
http://www.goldenpages.ie/: This is an FCR site which seems to work. “Yellow Pages” style classified business directory. Choose from the list of business categories or type in your search under “I’m looking for”.
