List of Eircode routing areas in Ireland
{{Short description|Postal and delivery service address coding element}}
The list of Eircode routing key areas in Ireland is a tabulation of the routing key areas used by An Post and other mail delivery services for the purposes of directing mail within Ireland. A routing key area "defines a principal post town"{{cite web|url = https://www.eircode.ie/what-is-eircode | title = What is Eircode? | work = Eircode.ie | date = July 2015}} according to An Post. There are currently 139 routing key areas in the country. This table does not include the second part of Ireland's seven-character Eircodes, known as the "unique identifier". These are unique to individual addresses and are not street-level identifiers, as is the case in other countries. There are currently 2.2 million of these codes.{{cite web|url = https://www.locpin.com/blog/eirecode-five-years-on | title = Eircode: Five Years | work = Locpin.com| date = July 2020}}
Scope
Although Ireland's routing key areas take a similar format to postcode areas in the United Kingdom (including Northern Ireland), they are not intended as a mnemonic for a county or city name, except for those used in the historic Dublin postal districts. Several towns and townlands can share the same routing key.{{cite web|url = https://www.citizensinformation.ie/en/consumer/phone_internet_tv_and_postal_services/eircode.html | title = Eircode | work = Citizensinformation.ie | date = May 2020}} A routing key coupled with a unique identifier looks like this:
