The launch of a national postcode system (Eircode, Irish éirchód) in Ireland began on 28 April 2014. The system incorporates the existing numbered Dublin postal districts as part of the routing key. Eircode made Ireland the first country in the world to have a unique postcode for each address. The codes, known as "Eircodes", consist of seven characters. The first three characters, called the "Routing Key", are designed to benefit the postal and logistics industry and contain on average 15,000 addresses each. The Routing Key is used to help sort mail, it is the principal Post Town of the address as defined by An Post. The second part of the Eircode, called the "Unique Identifier", consists of four characters drawn from a set of randomised letters and numbers that identify each individual address. They are stored in a central database, Eircode Address Database (ECAD), along with other useful geographic information including addresses, variants/aliases, and geo-coordinates of each address point.
