I don't know how detailed the post codes there are .. but if features in
OSM surrounding it were of the same post code (and correct) then they
could be used to derive the post code?
It will almost certainly share a postcode with at least one neighbouring
property, yes. A filling station is not going to receive enough post to
justify a "large user" postcode. So if it's surrounded by properties
that all have the same postcode, then that's definite enough. But if one
neighbour has one postcode, and a different neighbour has a different
one, then we can't be certain which is correct for this property... :-)
