Not the new Eircode Irish postcode system. This is an opensource geolocation code which automatically works from any location, everywhere you need, and not just postal addresses - with uses for infrastructure, inventory, agriculture, industry, tourism, field-work, search and rescue, and emergency service.

Ireland Postcode: Calculated to 8 characters plus checksum, 6 characters should be adequate for general addressing. Some will be less. Zoom out to produce and test shorter, easier codes. The checksum is optional. Use the code to text friends a location or to quickly record a location for yourself. Ideally Ireland would have an official postcode so that codes could be used for addressing and for use with emergency services and other location services such as roadside rescue. The app includes links to Hit The Road and Fix My Area services in Ireland.
Other geolocation codes are available for Ireland: Loc8Code and GoCode. Both achieve the same ends but are proprietary codes used under license. Only the OpenPostcode is freely calculated and used and is the most accurate code available. Geohash-36 calculations are also available. See www.OpenPostcode.org for more information.
For further information on the code, the calculations, and sample spreadsheets, see www.OpenPostcode.org.
