What is Eircode?

Smart address code

Eircode, Ireland’s postcode system launched in July 2015. Eircode enables people and businesses to find every address in Ireland, helping you to find life easier.

Over 35% of addresses in Ireland share their address with at least one other property, making it difficult for those delivering goods and services to accurately identify the location of an address. Eircode has been 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.

Having an Eircode, removes the hassle and mistakes out of finding addresses in Ireland.
