Plans to introduce a system of postcodes across the country have reportedly been postponed indefinitely by new Communications Minister Eamon Ryan.
Mr Ryan's predecessor, Noel Dempsey, had indicated that the 15m scheme would be up and running by the start of next year.
Two reports have already been compiled and an extensive public consultation process has been carried out.
However, reports this morning say Minister Ryan has now ordered another round of public consultations and has yet to decide if and when the system will be introduced.
