Passports are normally issued in the name on the applicant's birth certificate. Where the applicant wishes to use a name other than that on her/his birth certificate, and this differs significantly from the latter, evidence will be required showing that the name in question has been used by the applicant over a reasonable period of time.
Passports are issued showing the Irish form of the applicant's name provided that the Irish version used is a recognised, meaningful and standardised versions of the name or that the non-Irish version can be translated into the Irish language in a manner consistent with Irish language criteria.
