The name of the post town associated with the premises for postal delivery purposes. This includes Dublin Postal Districts "Dublin 1" to "Dublin 24".

The post town is a significant element of the Postal Address, however it is not always populated in an address. The official post office guide, Eolaí an Phoist4, describes post towns in the following manner:

"A provincial postal address may include the name of a town or village several miles distant, with which the addressee has little or no connection, and, in some places, especially if this residence happens to be near a county boundary, the name of the neighbouring county instead of the county in which he actually resides. The explanation is that the main mail despatches have to be sent for more detailed sub division to certain centres known as POST TOWNS, chosen because of their accessibility and convenience."

post_county

string [0 .. 30] characters

One of the 26 Counties in the Republic of Ireland. These counties are sub-national divisions used for the purposes of administrative, geographical and political demarcation. Post County is the County associated with the Post Town, not the geographic county in which the building is located. The Post County is normally used as part of the Postal Address with some exceptions e.g. Dublin Postal Districts where the Post County is not used and some Post Towns (e.g. Tipperary, Kildare, etc.) that have the same name as the Post County.

eircode

string [0 .. 60] characters

The seven character Eircode has an A65 F4E2 format. The Eircode is a mandatory address element. The last line of a Postal Address will contain the Eircode, displayed with a space. e.g. A65 F4E2.

The Eircode is always the last line of a Postal Address generated within the state, e.g. if an address has four lines then the Eircode will be on its own on Address Line 5. For inbound international mail the country name IRELAND should be appended as the last line of the Postal Address.
