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



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 (NDC), the first digit of which indicates the geographical area or type of service (e.g. mobile).

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 (excluding the leading 0), and subscribers' numbers are between five and seven digits.

As optional local dialling is facilitated, Irish geographic numbers cannot begin with 0 (trunk prefix), 1 (special number prefix) or 999 (emergency services). 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, 0xx 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:

  • 01 – Greater Dublin Area
  • 02 – Cork
  • 04 – Northeast
  • 05 – Southeast
  • 06 – Midwest and Southwest
  • 07 – Northwest
  • 09 – West

The Midlands is covered by several regional codes.

Except for the 01 area, each area is further subdivided into smaller areas (NDCs). Usually, the main city or town in the area is 0x1 e.g. 021 (Cork), 061 (Limerick), 091 (Galway).

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.

Mobile network operators (MNOs)

083 and 086 Three Ireland 086 previously belonged to O2.
085 eir mobile previously known as Meteor and eMobile
087 Vodafone Ireland formerly Eircell

Mobile virtual network operators (MVNOs)

Clear Mobile Hosted on Vodafone
08948Hosted on Three. Numbers begin with 2 and 4
Tesco Mobile
Lycamobile Hosted on Three. Numbers begin with 9
Virgin Mobile Hosted on Three. Numbers begin with 60 and 61

M2M (Machine to Machine) Communication

088All networksReserved for machine-to-machine (M2M) communications, using the format 088 xxxxx xxxxx. This prefix was originally used for the Eircell TACS network active from 1985 to 2001.

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 (e.g. Vodafone, eir Mobile), while others request a phone number followed by the voicemail greeting for that number (e.g. Three). 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.

Call management services / supplementary service codes

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.

Number changes

Several major number changes have occurred since 1990.



  1. In 2002 the Portumna MNA split from the area code 0509 and merged into the new area code 090.



Older changes

Possible future changes

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. [3]

Historical numbering

Defunct access codes

Defunct operator services

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

Historical Northern Ireland access codes

Belfast could previously be reached by dialling 084 in place of the UK area code 0232. [6]

Historical Great Britain access codes

Until the early 1990s, the 03 numbering range was originally used for calls to Great Britain, [7] including the Channel Islands and the Isle of Man, with the Irish prefix 030 replacing the UK trunk code 0. [5]

Calls to British cities using the director telephone system were also possible using shorter codes:

031 was replaced with 03071 [10] and 03081 [11] 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 (but not Northern Ireland) requiring the country code +44 and the area code in full. [12]

Premium-rate telephone numbers are telephone numbers for telephone calls during which certain services are provided, and for which prices higher than normal are charged. Unlike a normal call, part of the call charge is paid to the service provider, thus enabling businesses to be funded via the calls. While the billing is different, calls are usually routed the same way they are for a toll-free telephone number, being anywhere despite the area code used. These telephone numbers are usually allocated from a national telephone numbering plan in such a way that they are easily distinguished from other numbers. Telephone companies typically offer blocking services to allow telephone customers to prevent access to these number ranges from their telephones. In some jurisdictions, telephone companies are required by law to offer such blocking.

A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls instead of incurring charges to the originating telephone subscriber. For the calling party, a call to a toll-free number from a landline is free of charge.

A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of administrative regions of the public switched telephone network (PSTN) and they are also present in private telephone networks. For public number systems, geographic location plays a role in the sequence of numbers assigned to each telephone subscriber.

Telephone numbers in China are organized according to the Chinese Telephone Code Plan. The numerical formats of landlines and mobile phones are different: landlines have area-codes, whereas mobile phones do not. In major cities, landline-numbers consist of a two-digit area code followed by an eight-digit inner-number. In other places, landline-numbers consist of a three-digit area code followed by a seven- or eight-digit inner-number. The numbers of mobile phones consist of eleven digits.

Telephone numbers in Hong Kong are mostly eight-digit. Fixed land line numbers start with 2 or 3, mobile (cellular) phone numbers with 5, 6, 7 or 9, pager numbers with 7 and forwarding service with 8. Since the end of 1989, there have been no area codes within Hong Kong.

Telephone numbers in Singapore Wikipedia list article

Telephone numbers in Singapore, also known as the National Numbering Plan, are regulated by the Info-communications Media Development Authority (IMDA). Due to the small geographical size of Singapore, there are no area or trunk codes; all numbers belong to one numbering area, and thus come in the same 8-digit format. Numbers are categorised based on the first digit, thus providing ten possible categories, of which six are currently in use and the remaining four reserved for future usage.

Widespread UK telephone code misconceptions, in particular brought on by the Big Number Change in 2000, have been reported by regulator Ofcom since publication of a report it commissioned in 2004.

The dialling plan for mobile networks and new landline operators is closed; all subscriber numbers must be dialled in full. For landline numbers starting with 02, the dialling plan used to be open; the trunk digit and area code could be omitted if the caller was in the same area code as the callee. However, starting May 3, 2008, all landline numbers must be dialled in full.

Telephone numbers in Belgium Wikipedia list article

A telephone number in Belgium is a sequence of nine or ten digits dialed on a telephone to make a call on the Belgian telephone network. Belgium is under a full number dialing plan, meaning that the full national number must be dialed for all calls, while it retains the trunk code, '0', for all national dialling.

The national conventions for writing telephone numbers vary by country. While international standards exist in the form of the International Telecommunication Union sector ITU-T issued recommendation E.123, national telephone numbering plans define the format and length of telephone numbers assigned to telephones.

Telephone numbers in Panama Wikipedia list article

All telephone numbers in Panama are seven or eight digits long and there are no area codes. All numbers beggining with 6 and with 8 digits are mobile numbers. All landline numbers have 7 digits. The first digit of landline numbers may be used to vaguely identify the location of the caller. Mobile phones were also assigned 7 digit numbers until 2005, when they were moved to their own number space with 8 digits. Mobile numbers are recycled if the user is marked as inactive by the mobile service provider, and landline numbers are also recycled if a user cancels their landline phone service.

Telephone numbers in Georgia (country) Wikipedia list article

There were changes to the telephone numbering plan in Georgia which were expected to be completed by the end of 2011. This article is being updated after all the major changes, also the dates of these changes are indicated.

Telephone numbers in the United Kingdom have a flexible structure that reflects their historical demands, starting from many independent companies through a nationalised near-monopoly, to a system that supports many different services, including cellular phones, which were not envisaged when the system was first built. Numbers evolved in a piecemeal fashion, with numbers initially allocated on an exchange-by-exchange basis for calls connected by manual operators. Subscriber numbers reflected demand in each area, with single digit telephone numbers in very rural areas and longer numbers in cities.
