From Boston triple-deckers to Cricklewood building sites, this is where the Irish abroad ring home to a landline in Kerry or a mobile that has moved networks three times.

To reach a Ireland number from the United States, dial these three parts in order.
011 353 85 012 3456
From any mobile, anywhere in the world, you can dial +353 85 012 3456 instead. Press and hold 0 to type the +, and the phone picks the right access code for wherever you are.
Numbers in Ireland are written locally with a 0 in front, like 085 012 3456. Calling from abroad you leave that 0 out, so it becomes +353 85 012 3456.
A typical Ireland mobile number is 9 digits after +353. If a call does not connect, count the digits first.
Only the first part changes. Your access code replaces the 011, then 353 and the number stay exactly the same.
A ~ means wait for the second dial tone before dialing the rest. It is not a digit you press.
Calls to Ireland are $0.13 a minute, billed by the minute. There is no connection fee, no monthly plan, and no minimum spend. You add prepaid credit from $5, and it never expires.
Only for the time you actually talk.
Top up once, use it whenever.
Any number, nothing to install.
The dominant inbound corridor is the United States, home to roughly 35 million people of Irish descent, the second largest ancestry group in the country - U.S. News. The calls cluster where the 19th-century famine ships landed and where later waves settled: Boston (the highest share of Irish-Americans of any major US city), New York City (over 500,000 residents of Irish descent, the largest raw number), Chicago, Philadelphia, and the New England states, with New Hampshire at 20.4% Irish leading every state - Irish Americans in New York City. These are grandchildren tracing a 053 Wexford or 091 Galway landline through genealogy, J-1 summer students calling parents from Cape Cod, and the undocumented Irish in the Bronx and Dorchester who left in the 1980s and still ring home every Sunday.
The second corridor is Great Britain, where the Irish diaspora is the largest single Irish community in Europe, concentrated in London (Kilburn, Cricklewood), Birmingham, Manchester and Liverpool - Irish diaspora. Britain-to-Ireland is a genuinely everyday call, not a special-occasion one. Add Australia (Sydney, Melbourne, Perth, magnets for post-2008-crash emigrants) and (Toronto, Vancouver). Because so much diaspora contact now targets an that its owner carries across borders, callers dial the same +353 number whether the person is in Tralee or temporarily working abroad.
From the US, dial your exit code 011, then Ireland's country code 353.
Drop the trunk 0 from the Irish number. A Dublin landline written 01 401 2345 becomes 1 401 2345; a mobile written 087 123 4567 becomes 87 123 4567.
Dial the area code (or the 8x mobile prefix) followed by the local digits: for the example, 011 353 1 401 2345.
On a mobile or a browser dialer, just enter the number in +353 form (+353 1 401 2345) and the + handles the exit code automatically.
Always drop the leading 0 when dialing from abroad; it is a domestic trunk prefix, not part of the international number - Wikipedia. Landline length varies (Dublin 01 has 7 local digits, some rural exchanges have fewer), so if a fixed-line call fails, recheck the local-number length rather than assuming a fixed count - ComReg. Mobiles are always exactly 10 digits including the 0 (so 9 digits after +353). Avoid dialing any 1850 or 1890 number: those ranges were withdrawn on 31 December 2021 - ComReg. Belfast and the North are +44 28, not +353.
Ireland runs an unusual open numbering plan for geographic lines, meaning landline numbers are not all the same length - ComReg. There are around 50 area codes covering roughly 106 minimum numbering areas, with codes between one and three digits after the 0 and local numbers of 5 to 7 digits - Wikipedia. A Dublin 01 number carries 7 local digits, but a small rural exchange on a 074 or 071 code may have fewer. This is the single biggest source of confusion for foreign callers: there is no one length to validate against for fixed lines, only for mobiles, which are a strict 10 digits in a closed plan - Wikipedia.
The most consequential recent reform hit non-geographic numbers. On 31 December 2021 the old 1850 and 1890 shared-cost ranges and the 076 VoIP range were switched off, and from 1 January 2022 only 1800 Freephone and the new standard-rate range remain - . This matters right now: countless banks, utilities, government helplines and doctors' surgeries printed a number on old letterhead, and dialing it today gets you a dead tone. If a helpline number you have starts or , it is stale; look up the current or version - .
An Irish number has three moods and it pays to recognise each on sight. A mobile always opens 08: 083, 085, 086, 087 or 089 for consumer lines, followed by 7 digits, so 087 123 4567 is a phone in someone's pocket - Wikipedia. A landline opens with a geographic code: 01 for Dublin, then 02x, 04x, 05x, 06x, 07x, 09x codes fanning out across the country, with the local part running 5 to 7 digits depending on the exchange - ComReg. A non-geographic number opens 1800 (free), 0818 (standard rate) or 15xx (premium), and you should treat anything starting 1850 or 1890 as expired.
In international E.164 form you replace the trunk 0 with +353. So Dublin's 01 401 2345 becomes +353 1 401 2345, and the mobile 087 123 4567 becomes +353 87 123 4567 - Wikipedia. Save contacts in the +353 form and they work whether you are dialing from Dublin, Denver or Dubai. The one number you never internationalise is an emergency call: and both reach Irish emergency services and are dialed as-is.
Ireland has had full mobile number portability since 2003, and the practical consequence is blunt: you cannot tell which network a mobile is on from its prefix - Wikipedia. The prefixes were originally carrier-branded (087 for Vodafone, 086 and 083 for Three, 085 for eir, 089 for MVNOs like Tesco Mobile, Lyca and Sky), but two decades of switching means an 087 number today may sit on any network - Wikipedia.
Why this matters to you as an overseas caller: it doesn't, and that is the point. With a browser-to-phone service that bills one flat Irish mobile rate, network is irrelevant; you dial the full 08x number and it connects regardless of who now operates it. Note also that 088 is reserved for machine-to-machine and IoT, not people, so if a number starts 088 you are not going to reach a human - ComReg.
This is where the 1850/1890 withdrawal bites hardest. Irish banks (AIB, Bank of Ireland, PTSB), Revenue, the Department of Social Protection and countless utilities historically published 1890 shared-cost numbers, all of which stopped working after 31 December 2021 - ComReg. Most now sit on 0818 or, for the free ones, 1800. Citizens Information and many state-funded services moved their helplines to the 0818 prefix during that migration - Citizens Information Board.
A crucial practical point: many 1800 and 0818 non-geographic numbers do not accept calls from outside Ireland. If you are calling a Dublin bank branch or a government office from the US, always find and dial the geographic 01/021 landline for that office rather than its national 1800/0818 line, which may reject international traffic outright. Direct 01 or 021 numbers behave like any normal international call and get you straight to a switchboard.
One of the most common mistakes for anyone new to Irish calling: Northern Ireland is not on +353. Belfast, Derry, and the six counties use the United Kingdom code +44 with area code 028 - Wikipedia. So a Belfast number is +44 28 xxxx xxxx, not a variant of +353. From the US you dial it as a UK call.
Inside Ireland there is a neat shortcut that reflects the island's shared life: from the Republic you can reach a Northern number by dialing 048 followed by the 8-digit local number, instead of the full 00 44 28 international format - Wikipedia. That 048 access code only exists for Republic-to-North calls; from anywhere else in the world you must use +44. If your relative is in Donegal it is +353, if they crossed to Derry for work it is +44, even though the two towns are minutes apart.
In Irish homes, especially outside the cities, the landline still matters. An older parent or grandparent in a rural townland on a 065 Ennis, 074 Letterkenny or 051 Waterford line may treat the house phone as the real phone and the mobile as an afterthought, so a landline call can be the surer way to reach an elder in the evening. Younger Irish people are effectively mobile-only, and reaching them means an 08x number.
There is no off-peak or cheaper night rate to game here, and no reason to time a call for money: Irish landlines and mobiles simply ring when you ring them. The thing worth timing is the person's day, not a tariff. A landline in the west of Ireland is answered in the kitchen; ring at dinnertime (roughly 6 to 7pm Irish, so early afternoon US Eastern) and you will get whoever is home.
Ireland uses an open numbering plan for geographic numbers, so landline local parts run anywhere from 5 to 7 digits depending on the exchange, and area codes are 1 to 3 digits long - ComReg. A Dublin 01 number has 7 local digits; a small rural exchange can have fewer. Only mobiles are a fixed length.
The 1850, 1890 and 076 ranges were switched off on 31 December 2021 - ComReg. Organisations moved to 1800 (free) or 0818 (standard rate) numbers, and many state services adopted the 0818 prefix - Citizens Information Board. From abroad, dial the office's geographic 01 or 021 landline instead, since national 1800/0818 lines often reject international calls.
No. With full number portability since 2003, a prefix no longer reliably indicates the network - Wikipedia. An 087 number may now sit on any operator. It makes no difference to reaching them: you dial the full 10-digit mobile and it connects wherever it has been ported.
No, Northern Ireland is on the UK code +44 with area code 028, so a Belfast number is +44 28 xxxx xxxx - Wikipedia. From the Republic you can use the shortcut 048 plus the 8-digit number instead of 00 44 28, but from the US or anywhere else you must dial it as a normal +44 UK call.
Fraudsters spoof Irish 01 and 087 caller IDs so calls look local, part of a nuisance-call problem ComReg valued at over 300 million euro a year - ComReg. Since October 2024, mandated network filters block foreign calls faking Irish numbers and had stopped over 131 million scam calls by late 2025 - Irish Examiner. A genuine, properly-formatted international call is the reliable way to get through.
Ireland is 5 hours ahead of US Eastern and 8 ahead of Pacific, in a single time zone (UTC+1 in summer, UTC+0 in winter). Calling 7am to 2pm ET lands at midday to early evening in Ireland, ideal for reaching family. There is no cheaper night rate, so time the call to the person's day, not a tariff; ring an elderly relative before 3pm ET so it is not yet late evening there.

Start callingDialing out of Ireland starts with 00, the international access code shared across the EU, then the destination country code - Wikipedia. So from a Dublin phone the US is 00 1, Britain is 00 44, Australia is 00 61. The single most common outbound destination is Great Britain: with a huge cross-border workforce, family in London and Manchester, and business between Dublin and the City, Irish-to-UK is the busiest lane. The one quirk every Irish person knows is Northern Ireland: it is technically the UK (+44, area code 028), but from the Republic you can skip the international format and dial 048 followed by the eight-digit number instead of 00 44 28 - Wikipedia. Beyond Britain, the heavy outbound corridors mirror emigration: calls to relatives in the US, Australia, Canada and to workers in the Gulf. On a mobile, most people just save numbers in +353 or +44 format and never think about the 00 at all.
Spam and spoofing are a real, quantified problem: ComReg estimated over 89 million annoying and 31 million distressing nuisance communications in a single year, with harm conservatively over 300 million euro annually - ComReg. The classic scam spoofs an Irish 01 or 087 number so it looks local. Since October 2024, ComReg-mandated network filters block calls from abroad faking Irish geographic and mobile numbers, plus unallocated and Do-Not-Originate numbers, and had blocked over 131 million scam calls by late 2025 - Irish Examiner. The knock-on effect for legitimate diaspora callers: a genuine international call that presents an odd or Irish-looking caller ID can be caught, so a call from a real, properly-formatted international line is the reliable way through."
