An Post records postal addresses of new and changed buildings in its CAD database. A postal address is a routing instruction to An Post and the post town is associated with an address for postal delivery purposes only and allows for delivery of post as efficiently as possible.
The most comprehensive address database available in the country is the postal address database, which is owned by Geo-directory, a subsidiary company of An Post and Ordnance Survey Ireland. Eircodes are assigned to new property addresses using a valid postal address and verified geo-locations. An Post collects information on new and existing buildings, as well as changes to existing addresses and Ordnance Survey Ireland provides the geo-locations for these buildings. An Post GeoDirectory, a subsidiary company of An Post and Ordnance Survey Ireland, issue a new release of the GeoDirectory database file on a quarterly basis to Eircode in accordance with their licence agreement.
If an individual has a query regarding their eircode they should contact eircodes@anpost.ie.
