List of Eircode routing areas in Ireland

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.

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.

[2] 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.
