Communications Minister Eamon Ryan says his plan to introduce postcodes around the country will lead to more efficiency.
Mr Ryan announced yesterday that he would be seeking tenders for a contract to introduce the new system and hoped it would be operational within two years.
Under the plan, Dublin's current codes will be scrapped and every address in the country will instead be given a code including three letters and three digits.
The idea was first examined a number of years ago, but the cost of establishing the system is expected to be significantly lower at the moment as a result of the recession.
Mr Ryan says one of the most obvious benefits of the new system will be to help the emergency services locate addresses.
