Ireland is unusual in that it doesn't have formal postcodes.
Irish addresses are given in a reasonably straightforward format
Firstname Surname
Townland or Streetname
Smallertown
Biggertown
Co. Whatever
So, if you're posting to Co Donegal, simply place Co Donegal as the last line and once it reaches the postal service within the county, they'll send it onward. For example, to send something to the town of Letterkenny in county Donegal, a typical address could be like this:
Mr. A Smith
1 Main Street
Letterkenny
Co. Donegal
Ireland.
