By "number" I meant "name or number", since some buildings don't have a number. A flat number is obviously also necessary if applicable.
A previous discussion on this, in 2013, tried to give some examples. None of them seem to break the rule, since "Pleasant Cottage" and so on are building names. If there's a counterexample, Wikipedia should be updated.
In the US, that's actually kinda surprising to me. Even in the suburb where I grew up, where there's no obvious overall grid system and instead the streets tend to meander around, parallel streets in the same neighborhood tended to share a lot of numbers.
I think they are giving all houses a number now, most houses around me (south west uk) have a name and a number now, where they all used to have names.
My house has a number, but for some reason it's listed under the "name" of my house - no end of confusion.
