Hallo CM2DD -

no there are no postcodes in Ireland - Dublin has local post codes, and I assume Cork and other larger towns might have, but there is no British or German equivalent to post codes.

AS to an address:

Mr. O'Rourke,
'The Hives'
15 Ballyhoney Rd.
Ballybunion,
Co.Clare

IRLAND - if sending from Germany

Thanks odondon. I have a letter here where the sender has written "IRISH REPUBLIK" (I think it's meant to be German); would "IRISH REPUBLIC" be unsuitable?
