Ireland's country code is +353. From the US, dial +353 then the Irish number with the domestic leading 0 dropped. A Dublin landline printed as 01 XXX XXXX is +353 1 XXX XXXX. An Irish mobile printed as 08X XXX XXXX is +353 8X XXX XXXX. Do not keep the 0 after +353: +353 01 is a misdial.
How to dial
Use one of these origin formats:
- âș+353 plus the national significant number (usual on a mobile)
- âș011 353 plus the same digits from a US landline that still needs the North American international prefix
011 is the US international access prefix in FCC consumer guidance. + is a substitute on many mobiles. Do not assume every device accepts the same input.
More numbers: call Ireland. Area codes: Ireland calling codes.
ComReg numbering conventions: inside Ireland you dial trunk 0 plus the national significant number. Internationally you omit that 0. The ITU E.164 list assigns 353 to Ireland.
Dublin geographic numbers use 1 (printed 01). Cork uses 21 (printed 021). Irish mobiles use 8 after +353 (printed 08x). Number portability means a prefix is a format hint, not proof of the current network.
Cost
Calling Ireland from the US is an international call from home, not roaming in Ireland.
- âșIf the US plan lists Ireland in an inclusive international allowance, the handset can be the cheaper option. Check the destination list, not a generic "international" label.
- âșIf it does not, a carrier pay-per-minute add-on is a different product from a browser-to-phone rate. Confirm the carrier's own tariff before comparing.
- âșListed WorldDial rates checked on 13 September 2026: $0.04/min to landlines and $0.13/min to mobiles, in USD. Calls are billed in whole minutes, rounded up. Check the current rate for your number on rates before adding credit.
If Ireland is already in your US calling allowance, use your handset. If it is not, you can place the call in the browser. How calling works: how it works.
When 1800 does not connect
Irish 1800 is domestic freephone. ComReg 17/70a states that access to 1800 is not possible for callers outside Ireland. The same document states that 1850 and 1890 are not possible from outside Ireland.
Do not write 1800 as +353 1800. That is not the international form of a geographic number. Use a geographic or other paid number the organisation publishes for callers outside Ireland. Revenue Commissioners contacts for overseas callers are on Revenue Commissioners from abroad.
Time difference
Ireland uses GMT (UTC+0) in winter and IST (UTC+1) in summer. US Eastern uses EST (UTC-5) and EDT (UTC-4). Ireland is usually 5 hours ahead of Eastern time. The gap can shift by an hour in the weeks when only one side has changed clocks.
Use the office hours on the page you are calling. A general country guide cannot predict queue length.
Format mistakes to avoid
- âșKeeping 01 after +353 (Dublin must be +353 1)
- âșTreating 1800 as an international number
- âșConfusing roaming in Ireland with an international call placed from the US
