I’ve had to deal with postcodes in too many countries (logistic company), and the UK system is by far the best: dense, standard, somewhat intuitive, code-correcting, specific enough (several dozen households) that if you have a delivery, the recipient knows where the van is standing angrily. Documentation is excellent (relative to the UK government's digital service already very high standards), and you have APIs for all sorts of relevant conversions.
The only issues are what OC mentioned: some people don’t know a large building (50+ flats) can have several codes, and they are weekly updates because… ::magic dust:: construction!
The worst? Dubai: three inconsistent systems of varying length without any sense, standard, or redeeming features. The city road network is apparently even worse, so I guess those things work hand in hand?
The funniest? One person once joked that people in Ireland were not using postcodes, just the name of the nearby pub, which can get confusing as they often have the same name, so you also have to say the name of the second nearest pub…
I thought was funny, but I wasn’t sure that was a joke. Apparently, that was still true at the time? I saw a lot of discussion about “Introducing PostCodes in Ireland” and avoided those meetings so as not to sound clueless. We used Google Maps for a while during the transition.
I mean it's funny, but I don't know if I'd call it true. It was more that if you didn't know an address you could bet that the pub would help direct. (Probably wouldn't work anymore because all the rural pubs are closing)
Theres a difference between a system and embodied knowledge. I did a lot of work with systems which used Irish addresses early in my career.
"An Post", pre-eircode operated off a traditional hierarchical address system. Where there were "Counties" a real political boundary, "Post towns" which were usually big market towns but the location of a major sorting office, "Localities" (sometimes more than one) which were geographically undefined (we tried) at worst areas and some combination of street and buildings. The hierarchy was not strictly defined, it was a bit hungover.
My own address can be a combination of: <House number> <Street>, <Post town> <House number> <Street>, <Locality>+, <Post town>
Most of these were optional. The "Pub" thing is a testament to how awesome the staff at An Post are at just getting a letter to a door. If you needed to send a letter to "Mary O'Shea" who you knew lived in Kerry and near "Paudie O'Sheas pub" you can bet that if you put "Mary O'Shea, Near Paudie O'Shea's Pub, Kerry" you can bet the letter would get to Kerry, someone in Kerry would know Paudie O'Sheas is in Ventry, Send it on to Dingle and he postie doing the rounds in Ventry would be like "Ah right, thats for Mary" and the only catch being: about 60% of the Female population of West Kerry are probably called some combination of "Mary" and "O'Shea".
I'd imagine logistics companies were dancing for joy with every house having a unique post-code.
