Mr. Liam O'Sullivan:

The question was whether it was up to individuals to find out the Eircode location code of the people to whom they were writing. No, it is not. It is not mandatory, nor will it ever be made mandatory by An Post. If the code is on the letter, we will use it and if it is not, we will continue to deliver mail, as we normally do. Therefore, there should be no concern in that regard.
