Dun Laoghaire being D26 and Blackrock being D28 instead of that A64 and A96 nonsense. These random numbers make no sense as nobody will ever know them, people associate D24 with Tallaght and D15 with Blanch who will ever remember where K67 is? The north uses BT for the whole six counties so that that should've being a case point. The same with Cork should be C and Galway G. The system was designed to suit An Post and nobody else.

Who associates 18 with Sandyford? No one did until someone said "oh hey sandyford is 18" And people just remember it if they need to. Same as they will be capable of remembering A96 is dalkey. It's no big deal

Dublin post districts all have the letter 'D', which is the first letter of the city and county name. 2. All Northside districts have odd numbered codes. All Southside districts have even numbered codes. 3. Districts closest to the city centre have the lowest numbered codes. These all contribute to people understanding roughly where a postal district is, without having to learn off a random collection of prefixes (to say nothing of the random codes within each area). If Cork had a similar structure with letter 'C' then the same would apply in Cork. Ditto, Galway, Limerick etc.@Hannibal. The system was designed not to be useful without accessing the paid for databases. So, while other countries postcodes are useful to some extent without having to pay for access to a database, Eircode was designed not to be.

It doesn't help me at all Now I'm not knocking the Dublin postcodes, I'm just pointing out it makes no difference to anyone that they aren't sequential or in grid format.

The first - 1 - is at the centre and they spiral out like the shell of a snail. That way, the lower the number, the closest to the centre. Dublin postal districts are a bit like that - the (flying) snail was reserved for CIE.

ukoda wrote: » The point I'm making really is that it makes no difference what way they are structured. No one really complains. I really do see the logic in not assigning eircodes a county reference. We saw the uproar when the postal address was used and people cried murder when they were told they were "in the wrong county" can you imagine giving them an eircode with a T for Tipperary when they adamantly think they live in Kilkenny. At least with eircode you can change the database and the code doesn't have to change. Exactly how some retailers are showing the postal address secondary and the geographic address as primary. You can't do that with a code that has a reference to the county in it. The same applies to grouping houses within the code. There would be uproar of certain people weren't grouped with the areas they think they belong to.

ukoda wrote: » But that doesn't answer the question. Right now if I say my eircode stars with T you know I'm in Cork, if I say A you know I'm in Dublin county. What makes random numbers better than random letters? There's no benefit to having the structure you propose.

plodder wrote: » Surely, you understand that nobody just "knows" this. They have to learn it. If all city codes began with the first letter of their name, they wouldn't have to learn it. They would know it already. D = Dublin. C=Cork, G=Galway, L=Limerick The fact that there are always exceptions to these simple rules makes no difference whatsoever. It's about making the majority of postcodes recognisable, not 100% of them. Also, I'm not saying we should change to a code like that. I'm merely arguing that structured information (however imperfect) is nearly always more useful than unstructured information when it comes to recognition and memorability by the public.

ukoda wrote: » .. and the question was why didn't they extend that for the rest of Dublin, instead of using codes that begin with A and K? Because it was contentious enough in Dublin and they learned from it and didn't make the same mistake again in a national scale. Remember D6W? And why it exists. Imagine that times 10000 and that's why they didn't do it like that.
