Eircode makes every Irish address unique

Before the launch of Eircode in July 2015, over 35% of addresses in Ireland shared their address with at least one other property. This made it difficult for those delivering goods and services to accurately identify the location of an address.

Eircode was designed specifically to overcome this problem. Unlike other countries where postcodes define a cluster or group of addresses, a unique Eircode is assigned to each residential and business address.

The structure of an Eircode

An Eircode is a 7-character alpha-numeric code made up of two parts:

Routing key

The first part consists of three characters and defines a general area.

Unique identifier

The second part is unique to an address and distinguishes one address from another.
