Dialing Tips

  • Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in Ireland.
  • Use the + notation: From a US mobile phone, use +353 instead of 011 353.
  • Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
  • Save contacts in international format: Always store phone numbers with the full +353 prefix so they work from any country.
