Capita Business Support Services Ireland, trading as Eircode, was awarded a 10 year contract in December 2013 to develop, implement, maintain and promote the use of the National Postcode System "Eircode".
All postal addresses, geographical addresses and geo-locations are provided to Eircode from authoritative sources, namely An Post and Ordnance Survey Ireland respectively through their subsidiary company An Post GeoDirectory.
Eircode does not change existing addresses and the Eircode can be added to the address normally used for the property. This address can be the most commonly used address, postal address or/and the geographical address. The free to use online Eircode Finder (https://www.eircode.ie/) provides both the geographical and postal addresses for properties in the state.
The postcode system was designed to align with the postal network and therefore, the Eircode boundaries are aligned with the boundaries used by An Post for postal delivery.
