http://forum.geonames.org/gforum/posts/list/4.page JForum - http://www.jforum.net &postalcode_startsWith=815 the results always begin with 80331, while there does exist zip codes that go 815... is this feature not available for json, just xml? when i look up the docs, i can see the parameters for the xml call, but for json it says: Parameters : postalcode,country ,maxRows (default = 20),callback, charset (default = UTF-8) nice shades by the way. no chance for json postalcode_startsWith, or am i missing something? thanks for the help and thanks for this incredible service. ]]> http://forum.geonames.org/gforum/posts/list/6985.page#15520 http://forum.geonames.org/gforum/posts/list/6985.page#15520 GMT LookupJSON doesnt work, but there is a similar function that goes postalCodeSearchJSON and that does the trick. http://ws.geonames.org/postalCodeSearchJSON?lang=en&maxRows=10&username=demo&country=de&postalcode_startsWith=81]]> http://forum.geonames.org/gforum/posts/list/6985.page#15546 http://forum.geonames.org/gforum/posts/list/6985.page#15546 GMT
