Details for the new Irish postcode Eircode have just been announced on eircode.ie
. Information isn't complete but looks like there are to be some serious flaws in the new code. Hopefully these will be addressed before spring 2015.
"In 2015, Ireland will make a little bit of history. We're taking an exciting design leap to set a new world standard with our unique postcode system." - Eircode
Read the details ...
- It is an unremarkable version of the 19th Century UK Postcode.
- It is closed source and closed data which demands a license fee.
- Application will require access and updates for a large database.
- It is designed to code letterboxes only, not other points of interest, or infrastructure, or 999 locations.
- It is designed to be a randomised code, useless for statistical data and describing local catchments.
- It has no error-checking mechanism and codes can't even be check as looking like their neighbours.
- There is no guarantee that the code has solved the problem of accidentally creating offensive words.
- It entirely undermines data protection, personal privacy & safety. The postcode will always have pinpoint accuracy to your exact family household. No option.
- A "routing-key" is a plain nonsense. No code can predetermine where you are based and what your natural business catchment is.
- It is promised not to be repeated across the country, but D for Dublin continues the language bias against Irish. D for Dublin and random for everywhere else continues the place bias against everywhere else.
- Quite a lot of problem stems from trying not to upset D4, hobbling a nation's postcode to D postcode property vanity.
- This is another tax: a postcode tax which businesses will have to pay in order to stay competitive.

Ireland's most precise geolocation postcode: smart, free & open-source; covering the whole island of Ireland.
A fully extensible, independent, free and open geolocation code for a wide range of applications and precisions, efficiently describing single points and complex areas (released under the LGPL).
Born as a proof of concept that geolocation-postcodes can be trivial maths, and without the need for proprietary licenses and centralised management, it remains Ireland's most accurate postcode at 8 characters; while even at 7 characters at <3m average radial offset from a point - over 4 times more precise than Loc8code. For geolocation applications: at eight characters it extends to an accuracy of an average radial offset of ~.58m (inside an area just 1.2m x .92m), while the code is easily extended with even further characters. At 9 characters it is down to centimetre scale. At 10 characters it can provide geolocation coding for the entire globe.
On the whole locations nearby have similar codes. City Hall, Dublin, is at KFW-5X3L. The Central Bank is at KFW-6MW. The National Concert Hall is at KFW-KD2. The DCENR on Adelaide Road is KFX-FL6. While a house on the Blaskets is R37-4CJ.
- It is short, as short as any other and as short as you need it to be.
- It is clear, avoiding character confusion.
- Easy to remember, while neighbouring codes are largely similar.
- It is accurate, to an average distance of under 3m at 7 characters.
- It is scaleable and extensible to any application or purpose from 1 character to 10 characters capable of covering the globe.
- It is flexible, not just about mail and addresses, but for all sorts of locations, points-of-interest, postboxes, railway bridges, TV masts, telephone poles, pylons, manholes, petrol stations, lay-bys, in fact any geolocation data.
- It does not categorise. It does not navigate. It just points (navigation is for other systems).
- Each postcode is verifiable as correct by a built in checksum character.
- It has a published mathematical algorithm, free to use and to adapt, based on earth coordinates.
- The codes are mathematically logical and orderly.
- There is no language discrimination between Irish or English.
- The codes are objective: there is no such thing as a "select area" or posh code; it is maths.
- It is distinct from UK Northern Ireland codes.
- It is entirely free and released under the LGPL license.
Format: The code does not prescribe a format for display for individual codes. It is open to the specific application to apply formatting rules. For example, a postcode might prescribe the format KFP-XWT7 to delineate postal areas and specific addresses.
Precision: The code is open to any number of uses and required precision, depending on the purpose it can have any number of required characters. It is Ireland's more precise code available.
Parameters: The parameters for an Irish postcode as set via "west=-10.75; north=55.5; wide=5.4; high=4.2; digits=7". Using the code on a world scale generates a geolocation code in 10 just characters. Likewise, the OpenPostcode for Hong Kong is defined by "west=113.8; north=22.6; wide=.7; high=.5; digits=6".
Checksum: A checksum character is available at any precision level of the code.
