The recent history of the introduction of Irish postcodes is a messy and convoluted affair. In its current guise, the issue of a national postal coding system first appeared in 2005, when ComReg, the Communications Regulator, began considering their introduction. A Postcode Working Group met in early 2005 and produced a report recommending the implementation of a postcode system. The then Minister for Communications, Noel Dempsey, announced that postcodes would be introduced in Ireland by January 1st, 2008.
In June 2007, the new Minster, Eamon Ryan reportedly postponed the implementation of the system "indefinitely" pending additional public consultation.
