My home is 8 Avondale Park, Blackrock, sandwiched between 8 Avondale Lawn and 9 Avondale Park...... There are 3 "8 Avondale Park" places in Dublin....
The house comes up as 5 Carysfort Ave on Garmin (a row of houses all have that number...) and other mad things in other systems.
EIRCODE is the ONLY system that got it right, and we have to beat that into whoever we order a takeaway from, otherwise the food will be well travelled and stone cold when and if it ever arrives....
Go EIRCODE!!
