Eircode, Ireland's National Postcode System was launched on 13 July 2015. An Eircode is a smart location postcode for all Irish addresses. Unlike other countries, where postcodes define clusters or groups of addresses, an Eircode will identify an individual address – rural or urban – and help show exactly where it is located.
This means every residential address and business has a unique Eircode. There are a number of benefits to using Eircodes, the delivery of goods and services is easier and in a medical emergency an address can be quickly identified saving valuable minutes. You can continue to use your address as you usually do, simply add the Eircode on a separate line below the county.
