Eircode is Ireland's national postcode system that assigns a unique alphanumeric code to every address in Ireland. The Eircode consists of a routing key made up of three characters and a unique identifier of four characters separated by a space. The Eircode Address Database (ECAD) contains over 2 million Irish addresses along with their Eircode and geographic coordinates in different coordinate systems. Key tables in the ECAD like ADDRESS_POINT, SPATIAL_INFO, and POSTAL_ADDRESS provide address and location data that can be used in GIS applications to route to exact locations and provide improved services like emergency response, utility maintenance and delivery optimization.

What is an Eircode?
Eircode is a smart location code for all Irish addresses
Both Commercial and Residential
Every post box will have an Eircode
Every Eircode will have an XY (in IG, ITM and WGS84)
Addresses will not change – the Eircode will be added to
current GeoDirectory Addresses
Eircode will solve Irish Addressing problems i.e.
Vanity Addresses
Rural Addressing e.g. Ciaran Kirk, Greyacre Dundalk

How Eircode Works?
Routing Key
First three characters of each Eircode
It is not directly linked to counties, towns, or geographic features
Unique Identifier
Four characters drawn from a carefully selected set of letters and numbers that
identify each individual address.
The addresses will not be in sequence
Eircode should always be presented in upper case as two parts separated by a
space, on stationary, mail items, computer forms, etc. i.e. A65 F4E2 and never
A65F4E2

Eircode Products
Eircode Address File (ECAF)
Simple flat file format
Ideal for mailing / delivery companies
Does not provide XY
Eircode Address Database (ECAD)
Master database containing complete address and Eircode
information for over 2 million Irish addresses including XYs
ECAD contains no software; the data within it must be processed
for use in IT applications
ECAD is comprised of a number of database tables across a
number of categories

Key ECAD Tables for a GIS
ADDRESS_POINT
Every unique address within a building
Links to GeoDirectory
SPATIAL_INFO
Geographic coordinates
In 3 grid formats – ING, ITM and ETRS89
POSTAL_ADDRESS
Gazetteer search fields – building street, town etc.
Structure is based on GeoDirectory so will be relatively
easy to update existing gazetteers and address views

Eircode Benefits
Ability to route to exact XY and make use of power GIS:
Improved Blue Light responses
Better Utility and Telecommunications service provision
Accurate fault management
Routing applications - Distance to Duct etc.
Decreased delivery costs
Relatively easy to implement
Do not need to change address database – especially if addresses are
based on GeoDirectory
Can use spatial tools to match addresses that aren’t based on
GeoDirectory
Or customer can supply Eircode and self correct
