You can exchange your licence if it was issued by an EU or EEA country. If you want to exchange your EU or EEA licence, you must do so within 10 years of its expiry date. You can also exchange a UK licence.
A Recognised State driving licence may be exchanged up to a maximum of one year after it expires. After this period, applicants will need to apply for a learner permit.
If your licence was issued by a country that is outside the EU or EEA, you can apply to exchange it for an Irish licence if your licence was issued by a Recognised State for Exchange. Please see the National Driving Licence Service - List of Recognised States for Exchange
