Trying to create an apple id?

I got an iphone and i'm trying to create an apple id. It tells you to put in your postcode in the address except in ireland there are no postcodes and it won't let me continue. Does anyone know how i can skip it or solve the problem? I tried putting in EIRE and my county but it still says its invalid

Put a random postcode in there, if that doesn't work contact apple and ask them because they will be the ones who would know.

The only reason they ask for a postcode is to give you info about places near you so if you're happy about not getting correct info then it is ok to put in a random postcode!
