I think the duck test applies. It doesn't matter if a house number is assigned sequentially, or is based upon distance from some specified point, or is based upon some mad king throwing darts at a map: if it looks like a house number, is treated like a house number, and appears on the house/gate/whatever as a house number, then it's a house number. House numbers don't have to be sequential or monotonic, I can think of a couple of roads in my town where the house numbers are counter-intuitive. So it doesn't matter if those house numbers were assigned based on a distance along a road, and that subsequent road remodelling has resulted in them all being inaccurate without a milepost equation: if it quacks like a house number then it's a house number. If they're not house numbers marked somewhere on the property, and if there are sometimes (as the OP has stated) missing markers, and if road remodelling has rendered the distances incorrect, then what good is addr:road_marker in those particular circumstances? It appears addr:road_marker is only really applicable where all of the following apply: 1: The number is not marked on the property (otherwise it's a house number, however derived). 2) Road remodelling has not significantly changed the distances between the property and the two nearest road markers (so you know it's somewhere between marker X and marker Y). 3) Road markers have not been recalibrated following extensive road remodelling. -- Paul
