From 30 March 2017 all adults (ie those over the age of 18 on the date of renewal) can apply to renew their passport online.
For those applying for their first Irish passport or for applications relating to children (ie those under the age of 18 on the date of renewal), applications will continue to be made using the paper passport application form (form APS2), which can be submitted together with the supporting documentation through the Embassy. You can find details of how to do this, including the documents required and the fees, below.
Keep a record of your 11-digit application number to track your application. A peel-off sticker with the number can be found on the back page of the application form.
