Numbering Plan for Ireland

The Number Plan for Ireland lists all numbers and codes that are available on public telecommunications networks. These include

Geographic Numbers

Geographic numbers telephone numbers linked to a particular geographic location. A document showing the boundaries of Subscriber Trunk Dialling (STD) areas and Minimum Numbering Areas (MNAs) is available on this site (currently ComReg Document 03/147) or you can view the Area code maps online. Authorised undertakings with geographic number assignments and an OSI license can obtain soft copies of the maps, from which more precise boundaries can be determined, by contacting ComReg’s Numbering Division at numapps@comreg.ie.

Non-Geographic Numbers & Short Codes

Non-Geographic numbers are numbers where a geographic area is not directly identifiable from the number. The services covered by these numbers include freephone services, shared-cost services,  universal access services, premium rate services and Nomadic services.

Mobile Numbers

Mobile numbers are typically used within public land mobile telephony networks (e.g. GSM).

Number Changes

In order to ensure that adequate reserves of telephone numbers exist for all new customers and services, ComReg regularly audits the usage of existing numbers and keeps an especially close watch where previous audits have identified a potential scarcity.  Number changes are carried out from time to time, when number exhaustion is imminent in an area. The most recent changes occurred in 2003, 2006 and 2009  More detailed information on the 2003, 2005 and 2009 number changes is available here:
