Eircode, Ireland’s new postcode system has now been launched by the Department of Communications, Energy and Natural Resources. 

During the Eircode launch phase, an Eircode letter was sent to each residential address. This letter notified the occupant of the Eircode for that property. The letter will also included a handy pop-out card containing the Eircode for the address – be sure to keep this in a handy place and refer to it when you need to.

You can check the Eircode for your residence by using the following link:

Mayo County Council is committed to using the Eircodes when updating the Register of Electors and we would encourage you to include your Eircode in your address if you are registering to vote for the first time, if you have changed address or if you wish to amend your existing electoral address.  You may contact our office by email to or by telephone to (094) 9047353 / 9047334 / 9047313 for further assistance.
