English: Ireland launched a new postcode system on 13 July 2015 in which each address in the country was assigned a unique postcode. Five days later, this postcard was sent from the United States to a home in Ireland. No street address, town, or addressee name was written on the card but it was correctly delivered six days later because the unique postcode was provided.
