According to the National Irish Bank website:

If you lose your card or believe it to be stolen, notify your branch immediately or phone our 24-hour Emergency Telephone Service, which operates 365 days a year: 1850 700 221.

But if your phone package (mobile or landline) has inclusive minutes, you can call this number instead: 01 661 2822
