How broadly true is that[1] in the UK (I’m assuming UK here, and not AUS or NZ or some other anglosphere country)? And is it more true in rural areas vs the city? 1 - a post code resolves to something approximating a single physical address, or at least close enough to reliably allow delivery

Not broadly true in the UK. The median is probably 15 or 20. I've only ever lived in cities.

A post code is usually a few streets. Precise enough to prpbably figure put the restof the way in a pinch but still a pretty large number of potential addresses.

  A post code is usually a few houses, 15 on average according to Royal Mail, so that's usually a single street. There are exceptions in rural areas, where one post code covers multiple streets.

    It depends. My postcode covers more like 50.

    That is insanely specific. By contrast, my US zip-code covers at least 75 square miles, and that's a conservative estimate.

      It is extremely convenient when filling in online forms, giving an address over the phone, or when getting into a non-app taxi. Web forms and the in-car navigation prompt first for the postcode, then present a list of the full addresses and you pick one. Over the phone, "W10 6TR" also avoids needing to spell anything, and I encourage you to search Google for it. There's also some human readable part. The W means West London, people who live in West or South West London will be familiar with some numbers - W10 is Ladbrook Grove. B is Birmingham, BS is Bristol, BT is Belfast etc.

      Are you referring to the 5 or 9 digit variant? Presumably not the 11 digit one as that corresponds to your unique address. (It follows that the 9 digit variant corresponds to at most 100 mailboxes.) I've never tried inputting my 11 digit code in an online form but at least the 9 digit one is readily accepted. In my experience the last 4 will usually be completed for me based on the street address and if it can't find a match it gives me an error.

        I didn't even know there was an 11 digit code until now! I was referring to the 5 digit code. 9 digit would be closer, but around here 100 mailboxes (zip+4 would actually be 9999 mailboxes) is still quite a few square miles. If I look out my living room window, I can see maybe 10 houses, and that's with a view that comes from living on top of a hill.

        Zip+4 (9 digit) can't ever be more than 100 mailboxes because 11 digit is guaranteed unique. It follows that a 5 digit zip is limited to 1M boxes. Unless I have a misunderstanding about 11 digit being unique anyway.
