text: The reporter did not provide an explanation. Nobody came forward with knowledge about the situation to verify. I'm closing this. We could have a vague note for each and every missing house number in the world, but that wouldn't make any sense. This is not how OpenStreetMap works. If you have information about an entity that fits in one of the widely used tags, you should add it. On the other hand, there could be an infinite number of tags missing from each and every POI.
