Sam was making the case for sequential codes, and I pointed out that even if it was possible (it's not) it would lead to properties with near-identical, or actually identical addresses having near-identical codes, and that would give obvious scope for confusion. I pointed out that Eircodes are not assigned randomly; care is taken to make sure that addresses with similar Eircodes have starkly different addresses, and vice versa. The examples you give bear this out.
Where are you getting the figure of 16000? Are you suggesting that almost one per cent of the letters were misdelivered?
Don't you think that the people getting them would have been alerted by someone else's name on the envelope?
And in any case, it is trivially easy to verify it on the Eircode map.

You have two unique pieces of information to cross reference. It is highly unlikely that you would make the corresponding mistake in both pieces of information. I've explained this to you before.
GJG wrote: » That's flat wrong. It depends on what you call non-unique, the 35 per cent refers to absolutely no difference between the addresses; but there is still plenty of scope for confusion between 110 High Street and 101 High Street.

The first three characters are the same as your neighbours. That leaves 4 characters. Remembering 4 unique characters is not a difficult challenge, so yes the advantages far outweigh the "alleged" disadvantages.
You don't appear to understand the logical conclusion of your own argument.
This isn't 1972. Eircodes are entered on websites, provided to people who put them into CRM systems etc. The IT systems translate the data into usable, actionable data suitable for each use. For most private citizens that's simply entering into Google Maps and getting directions. For businesses it can be assigning to the correct Engineering area or Sales Territory, or Delivery Depot. None of that is done by staring at the code.
We're in the implementation thread, and I can state from my experience that none of the implementations I've been involved with have raised this as an issue. SUSI had a 92% Eircode rate on their forms (yes they were validated, no, people didn't just enter anything) so in the real world the last four characters of the Eircode do not present an issue. When evidence challenges your assumptions you are meant to change your mind.

Yes, it is more beneficial to all of rural Ireland. Non unique addresses were a priority of the design.
I always recognise the "if you make a small mistake with a hierarchical code you will be close to your intended destination" argument as an indicator of bias. You have to be completely biased to assume that the error in the Eircode will be in the last or second last character rather than the fourth or fifth character. How far away will you be then?
I do not think a design feature that assistes the National Ambulance Service to respond to an emergency faster is a "limited advantage".

PDVerse wrote: » 80% to 90% of cases reported are related to a location, a subset of those relate to houses or activities outside houses. The ECAD database contains spatial information (centre point and bounding boxes) for Streets, Townlands, etc. so this information about an address is useful to Waterford even if an actual Eircode isn't available or suitable.
GJG wrote: » You are precisely incorrect with this. Let's leave aside the impossibility of keeping a system sequential (and dealing with the inevitable confusion caused by a partially sequential system). Stressed communications are prone to error, and stark differences are important to avoid this. If your address was only one or two characters different to your neighbour, (remember that 40 per cent of people have an identical address to their neighbours, and most of the rest have only a single character difference). then the potential for undetected error is very high. You can never prevent all errors, the point is to make sure that errors are evident. 999 operators are trained to then ask first for the code, then for the address, even though they can see it on their screen once they enter the code. If the code is wrongly communicated, redundancy means a 99 per cent chance that it will be immediately evident, and the operator can ask for clarification. But if you give an incorrect Eircode that, by chance, is the correct Eircode for somewhere else, that will be instantly evident when you state your address. This happens because, contrary to you umpteenth restatement of the false claim that Eircode is random, it isn't. It is designed to make sure that no two addresses which are identical or even similar (even if they aren't physically close) have even remotely similar Eircodes. Under your suggested system, a small communication error could give a nearly-correct code, which resolved to an address, say 100m away, around a corner.

Another example (not my house) is D02 C656 and D02 C653. There are similar-ish things in rural areas. Just from a quick look H12 PK30 and H12 PK03 are both in issue and are not a terribly long distance from each other. H12 PK30, H12 PK31, H12 PK37 and H12 PK38 are all in issue. Perhaps there is a meanness about letter-use in the Cavan area? (That was unfair.) In a rural setting, there is no quality assurance done (that I know of) to ensure that the correct eircode has been delivered to the correct house. There is a very high probability indeed that over 16000 houses have not received their eircode or have received the wrong one, or multiple eircodes. What we have is a code that is highly granular, but that is not known to be particularly accurate. This is easy to see from Google Maps. (Now that these codes are going to be publicly available, largely for free on Google Maps, it is hard to understand why Eircode doesn't just publish the file. )

If the code was not random, then such a mistake would be less likely. That is a poor system. If my postcade was D04 ABCD, and it is expected my neighbours was D04 ABCE then such a mistake is obvious. If my postcode is D04 AT6J, and my neighbours is D04 P7MK, how is anyone going to spot that either one or both are wrong? It is the random nature of the code that gives rise to such inability to check if they are correct or not. If you get the right postcode, it might save costs, but get it wrong, and savings go out the window.
