Telephone numbers in the Republic of Ireland


Numbers on the Irish telephone numbering plan are regulated and assigned to operators by ComReg.

Overview

Telephone numbers in Ireland are part of an open numbering plan that allows variations in number length. The Irish format is similar to systems used in many parts of Europe, notably the Netherlands, Sweden, Germany, Belgium and France, where geographical numbers are organised using a logic of large regional prefixes, which are then further subdivided into smaller regions. It differs from UK numbering, which originated as alphanumeric codes based on town names.
Irish Mobile and non–geographic number are fixed length and do not support local dialling.
The trunk prefix 0 is used to access numbers outside the local area and for all mobile calls. This is followed by an area code, referred to as a National Dialling Code, the first digit of which indicates the geographical area or type of service.
Calls made from mobile phones and some VoIP systems always require the full area code and phone number.
In common with most European countries, the trunk prefix 0 must be omitted when calling Irish numbers from abroad.

General structure of Irish numbering

Irish area codes vary in length, between one and three digits, and subscribers' numbers are between five and seven digits.
As optional local dialling is facilitated, Irish geographic numbers cannot begin with 0, 1 or 999. However, mobile numbers use the full range of digits, as local dialling is not supported on mobile networks, and the area code must always be dialled.
A migration to a standard format, xxx xxxx, is in progress; however, to avoid disruption, this process is only being carried out as needed, where existing area codes and local numbering systems have reached full capacity. There is currently no plan to move to a closed numbering system.

Geographical numbering

Irish geographical numbering is structured on a regional basis and follows a logical hierarchy.
These directory areas correspond approximately to the following geographical regions:
The Midlands is covered by several regional codes.
Except for the 01 area, each area is further subdivided into smaller areas. Usually, the main city or town in the area is 0x1 e.g. 021, 061, 091.

Mobile services

Mobile phone numbers start with the prefix 08x and are part of a closed numbering plan, which means that a mobile phone number must have 10 digits. Calls to landlines and other mobiles require the area code on a mobile phone.
New numbers are assigned on prefixes and ranges managed by a specific operator. However, as full mobile number portability has been in operation since 2003, it is no longer possible to reliably identify which network a particular number is on. For example, a newly assigned Three number would begin with 083, but may have been ported to another operator in the meantime.

Direct to voicemail number

Mobile phone numbers also have their own voicemail number. To access this, the number 5 should be put after the prefix. For example, the mobile number 08x xxx xxxx has the voicemail number 08x 5 xxx xxxx.
On some networks, when the direct to voicemail number is called, the voicemail greeting for that network is played, while others request a phone number followed by the voicemail greeting for that number. Users can press the hash key to gain access to the voicemail box.

Calls to Northern Ireland

Although Northern Ireland is part of the UK numbering plan, a special arrangement exists for calling Northern Irish landlines from the Republic of Ireland.
Calls to Northern Ireland can be dialled using the 048 prefix or by dialling the number in the full international format. Most Irish operators treat calls to Northern Ireland at national or even local rates. Similar charging arrangements apply when calling the Republic of Ireland from Northern Ireland.
For example, to reach Belfast landline 90xx xxxx, subscribers can dial either 048 90xx xxxx or 00 44 28 90xx xxxx.
Northern Irish mobile phones use the same mobile numbering and networks as other parts of the UK – calls must be dialled using the 00 44 7xxx xxx xxx format.

International calls

In common with all EU countries, the international access code is 00.
Numbers should be dialled as follows: 00 – country code – area code – local number.
All mobile phones and some VoIP services also support the international E.164 number format, so a + may be optionally used instead of 00.

Reserved numbers

General operator assistance no longer exists in Ireland. It used to be available by dialling 10 from within Ireland.
The emergency number for Ireland is 112. This is harmonised across the EU.
To avoid confusion, the long–established 999 continues to be advertised alongside 112. Either number can be dialed.

Services provided

112 can also be contacted by SMS. While the service is open to all users, it is primarily aimed at the deaf community.
Pre-registration is required. Further information can be found at .

Special rate non–geographic numbers

Toll–free numbers are free to call from mobile handsets, however the recipient can elect not to accept mobile–originated calls, and/or to accept calls only from predefined geographical region.
NB: 1800 1850 &
1890 can only be dialled from within Ireland. They should never be printed or presented in the international format +353 1800, +353 1850 or +353 1890 as these clash with working Dublin landline numbers in the 01area +353 1 8xx xxxx
A recent review of non–geographic numbers will lead to the withdrawal of the 1850, 1890 and 076 number ranges by 1 January 2022. During the transition period, these ranges are geo–rated.
From August 2019, various telecoms providers announced price changes which took effect on, or just before, 1 December 2019, including , , , , , , , , and .

Special short codes are used to control various supplementary services offered by digital local exchanges. These services were first introduced as PhonePlus in 1981, on the first generation of Alcatel E10 and Ericsson AXE digital exchanges used in Ireland, and were rolled out nationally throughout the 1980s.
These services are available on all Irish PSTN lines, regardless of operator. There is a more expansive range of services available, but these are the most commonly used. Different codes apply on cable telephony lines, such as those provided by Virgin Media Ireland and on VoIP providers.

PSTN lines and some ISDN services

Caller ID services

When this service is active, the dial tone changes to a two–frequency 'siren' tone.

Alarm / reminder call

Most exchanges confirm setup with a verbal announcement, however some exchanges may use a ringing tone to indicate successful service setup and a busy tone to indicate an error/invalid code.

Mobiles

Several major number changes have occurred since 2000.

2002–2003

All local numbers with the area code 01 are currently 7–digits, but may change to 8–digits in the future, although breaking the city into separate area codes would match the rest of the national system.
A review and public consultation on the future of Ireland's numbering plan was undertaken.

Historical numbering

Defunct access codes

A range of numbers from 192, 193 and 194 were once used for various Telecom Éireann customer service and account service lines.

Defunct information services

Belfast could previously be reached by dialling 084 in place of the UK area code 0232.

Historical Great Britain access codes

Until the early 1990s, the 03 numbering range was originally used for calls to Great Britain, including the Channel Islands and the Isle of Man, with the Irish prefix 030 replacing the UK trunk code 0.
Calls to British cities using the director telephone system were also possible using shorter codes:
031 was replaced with 03071 and 03081 when 01 was split into the area codes 071 and 081 in 1990.
Use of 03 for this purpose was discontinued in 1993, when the international access code changed from 16 to 00, with calls to Great Britain requiring the country code +44 and the area code in full.
