Can I put a Republic of Ireland address on a Northern Ireland driving licence?
No. DVA can only record a Northern Ireland address on a Northern Ireland driving licence.
If you permanently move outside Northern Ireland, nidirect says you should contact the licensing authority in your new country of residence about the correct next step.
Do not leave an old Northern Ireland address on the licence simply because the online service will not accept an overseas address.
