I don't think so, except in cases where the postal regions are different from the administrative regions - but even there, the right answer would be to add areas for postal regions. In many countries, if a postal code is provided then the county and city are not needed for postal delivery, although they may still be included in long form addresses for humans (rather than mail sorters) to get an idea of where it is. It's my practice to tag addr:housenumber, addr:street and postal_code. The rest is implicit from the location on the map. Nominatim, for example, will work out what region a point is in. (It doesn't always do a good job, but the way to fix that is to improve the region areas on the map, not add redundant addr or is_in tags to every object.) That said, if you're mapping an area for the first time and you know that a house is 'in' a certain region, but not the exact boundary of that region, feel free to tag it on the house itself. It can always be improved later. -- Ed Avis <e...@waniasset.com> _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
