There is no one official address for any location address in Ireland and many versions of an address can exist such as geographic, postal, electoral, or historical addresses.
Buildings can have several addresses attributed to them by different organisations for different purposes e.g., postal addresses may record an address based on postal routes, or church records may record an address based on parish boundaries. Eircode does not change or replace these addresses.
The Eircode database which you can use with the Eircode Finder contains the geographic and postal address. Both of these addresses are provided to us by An Post GeoDirectory.
Eircode notification letters, sent when a new Eircode is assigned, have the postal address only, as this is the address that An Post recommends for the safe and efficient delivery of letters.
Eircode cannot amend or change these addresses.
