About GeoDirectory


The purpose of GeoDirectory is to create a definitive reference directory of addresses in Ireland and to assign to them accurate postal and geographic addresses.

A postal address is the address used to enable delivery of mail. A geographic address is a combination of East and North values which accurately position a building on the surface of the Earth.

Geographic addresses, also known as geo-codes, are commonly used by Geographic Information Systems (GIS) to position addresses on maps.

GeoDirectory combines accurate postal and geographic addresses for Ireland in one database.


GeoDirectory was established by An Post and Ordnance Survey Ireland to manage and maintain a database used as the de-facto standard of addressing in Ireland, the first set of data released dates from 1998. The database contains every residential and commercial building in Ireland with details for each address - location codes (3 types), EDs, Small Areas and Unique Building Identifier.

As well as information such as the type of property (Terraced/ Semi Detached, Industrial Unit,  etc), other details include whether  the property is a new build, occupied, vacant or derelict and the type of business being undertaken in the building if it is commercial.

GeoDirectory data includes NACE codes which is the European statistical classification of economic activities and organisations according to their business activities.
