You can apply in person at any of the 36 National Driver Licence Service (NDLS) centres nationwide. You must book an appointment to attend an NDLS centre. There is no walk-in service available.
If you have a Public Services Card (PSC) you can use it with a verified MyGovID to apply online. If you apply at an NDLS centre, you can use your PSC to simplify the process as it will satisfy the following requirements:
If you do not have a PSC you are required to present documentation at the NDLS Centre to satisfy 1. Photo ID, 2. Evidence of PPSN, 3. Evidence of Address, 4. Evidence of normal residence - see above for a list of acceptable documents for each.
In some cases the same document may satisfy more than one requirement e.g. an Irish/EU passport is adequate as photo ID & proof of residency entitlement; a letter to you from Revenue which shows your PPSN could be used as both proof of your address & proof of your PPSN.
