The writing may finally be on the wall for the exclusive postcodes of Dublin 4 and 6.
Although the authorities will still not confirm a move to a new system, it is now likely that multiple numeric and alphabetical postcodes, similar to those used all over Europe, will be introduced in the Republic in the next year or so.
The last Minister for Communications, Noel Dempsey, committed the department to the introduction of a postcode system as soon as possible and now industry sources say they will be introduced next year.
The new postcodes are likely to include the one and two character county codes currently used in vehicle registration plates.
The absence of a proper postcode system is believed by the Irish Exporters Association to be hitting international trade. The group said recently that the lack of postcodes made the Republic's system inefficient and was adding up to 30 per cent to An Post's sorting and routing costs.
Much of the delay in introducing the new system has been attributed to pressure groups who are insisting on keeping their own valuable postcodes intact.
If the furore that preceded the creation of the Dublin 6W postcode in 1985 is anything to go by, the next 12 months could see blood on the streets from Ballsbridge to Dartry.
In 1985 Dublin 6 was split, with areas such as Templeogue, Kimmage, Terenure and parts of Rathgar becoming part of the new district 6W, to facilitate the processing of mail.
Residents were offered the designation "Dublin 26" but refused point blank for fear of agreeing to devaluation of their properties by association with areas numerically close, like Dublin 24, which hosts Tallaght and Jobstown. The economics is difficult to dispute. Early last year two-bed apartments were selling for an average of €650,000 in D6. In D24 the average was €285,000.
