Repost from Reddit: https://www.reddit.com/r/dataisbeautiful/comments/8qt94a/endianess_of_date_and_address_formats_in_europe/
On the reddit comments some user wrote the address format for Russia is wrong on this map, they use big-endian as well.
Also Hungary is the only country in Europe where we use big endianness in names, aka Eastern name order: surname first, firstname second.
The adress map isn't correct once you factor in postcode.
Basically, in theory you can leave out the town and potentially even the street depending on country. It's redundant information, which is useful to double check, but you don't actually need to include it.
Eg. Here's the adress of BBC News:
In theory, the postal service needs the street, town, and postcode. But if you look up W1A 1AA you'll find it refers to BBC Broadcasting house in London.
In other words, if you want to write a letter to someone at the bbc, you can adress your letter like this:
The first two lines are for the BBC itself. The post only needs the postcode to correctly deliver the letter.
It's a similar thing for the Dutch adress. Prinsengracht 263 is the Anne Frank House. Apparently the museum entrance is:
But if you google the postcode you'll find it refers to Westermarkt 2 - 34 in Amsterdam.
So in theory if you want to adress something to the museum you could write:
In fact, this is exactly what people sometimes do to their bikes in the Netherlands. They have their postcode + house number inscribed on the bike, so that if it gets stolen there's more than enough information to prove who it belongs to.
In Ireland you can always leave out everything but the postcode, each code is unique to an address. For example D02 R583 is the address of Government Buildings in Dublin. It’s for all addresses, not just larger buildings.
Pretty cool.
