The Government is to be asked to approve the introduction of new post codes here in the near future.
The measure is aimed at making sure that mail gets to its intended destination faster.
It is estimated that almost half the addresses here are not unique and post codes are seen as a way of combating this.
The Department of Communications says consumers, businesses and public service would all benefit from a postcode system.
Three years ago then Communications Minister Noel Dempsey predicted the postcodes would be in place by the start of this year.
While An Post is known to have been lukewarm about the proposal because of the cost involved, the department now says proposals on their introduction will be brought to government very shortly.
The most likely system will comprise three letters followed by three numbers.
