Australian postcodes cover thousands. British Postcodes can be unique to a household.

Japanese postal addresses can be very unlike western addresses. The major unit chome then a sub, then sometimes an offset from a landmark or "street behind"

I've had late night taxi drives from stations have to check in at a Lawson to find the doorway.

Edinburgh has its own notation for which door on a stairwell which sometimes (if the gods will it) aligns to postal registry and council and utility billing. When it doesn't things get complicated. Glasgow, Dundee and Aberdeen all have their own variants of this stairwell door identifying notation as I understand it.

Dutch addresses putting the number after the street name can confuse people.

This one causes me problems _all the time_. My address is like:

    12 XYZ Lane,
    XYZ Road,
    Town Name
    Postcode

12 XYZ Road, Town Name is also an address that exists, and is in the same vicinity as me so will get routed to the same delivery driver, but is not my address.

So often enough, when continental European companies insist on a structured address, they will then render it back out as some variation of:

    XYZ Lane
    12
    XYZ Road
    Town Name
    Postcode
And the delivery driver just looks for the number as the start of the address, presumably because they're used to scanning past recipient names and business names, and instead delivers my package to 12 XYZ Road.

Number after the streetname seems to be a more general European thing.
