My original intention was to photograph all parts of greater Dublins at regular intervals in order to document any changes or developments within the Greater Dublin Area. However, I have over the last ten years encountered many unexpected problems.

On major problem is that it is a bit difficult to decide what is an area, a district, a suburb, a townsland or a village. After gaining some practical experience I now intended to use the postcodes described below as a framework going forward.

Dublin postal districts have been used by Ireland's postal service, known as An Post, to sort mail in Dublin. The system is similar to that used in cities in Europe and North America until they adopted national postal code systems in the 1960s and '70s. These were incorporated into a new national postcode system, known as Eircode, which was fully implemented in 2015. Under the new Eircode system, the Dublin Region incorporates the original routing areas D01 to D24, along with new A## and K## codes for the remainder of the county.


Post-1961 Dublin street sign displaying the street name in Irish and English, with postal district number

In Dublin city and its suburbs, a system of postal districts was introduced in 1917 by the Royal Mail with the prefix "D", and retained after Ireland became an independent country, without the prefix. However the use of district numbers by the public did not begin until 1961, when street signs displayed postal district numbers. Prior to that time, street signs only displayed the street name in Irish and English.

The Dublin system had 22 districts — Dublin 1, 2, 3, 4, 5, 6, 6W, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 22, 24. These were incorporated into the routing keys now being used with the Eircode national postcode system as D01, D02, D12, D22, etc.


The city of Cork had four numbered postal districts, but these were used internally by An Post and rarely on mail. Cork 1 covered the city centre and large parts of the surrounding city, e.g.: the "Patrick Street" (Sráid Phádraig) sign displays the digit '1'. Cork 2, administered from the Ballinlough sorting office, covered the south-east, Cork 3 (from Gurranabraher) covered the north-west while Cork 4 (from Togher sorting office) covered the south-west. The numbers are not used in the Eircode system,[5] with routing keys in the Cork area instead beginning with the letter 'T'.[2]

The launch of a national postcode system in Ireland began on 28 April 2014. The system incorporates the existing numbered Dublin postal districts as part of the routing key. According to the government the system made Ireland the first country in the world to have a unique postcode for each address (without requiring the use of building numbers).

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, however it is not directly linked to counties, towns, or geographic features. The second part of the Eircode, called the "Unique Identifier," consists of four characters drawn from a carefully selected 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.

Sample product data and pricing details were issued to businesses in March 2015. The ECAD is now available to licence by end-users and value-added resellers called Eircode Providers.

An example of a typical Irish address is that of the Lord Mayor of Dublin: The Eircode is added on as an extra line to the existing address and postal district code which remains unchanged.
