Some zip code queries against FindNearbyPostalCodesJSON are returning unexpected results suddenly. Some US zip code searches are no longer returning results, instead favoring other countries. Other zip code searches work correctly

e.g. zip code lookup for 98074 (Sammamish, WA, US) returns townships in Italy:
http://api.geonames.org/findNearbyPostalCodesJSON?postalcode=98074&username=[hidden]

unless I specify country:
http://api.geonames.org/findNearbyPostalCodesJSON?postalcode=98074&username=[hidden]&country=US

My recollection was that without a country specified all results would be returned.

The findNearbyPostalCodes service returns postal codes near to a given location. Normally the lat/lng of the location is passed as parameters. The service also accepts a postal code as parameter and will then return the closest postal code to the first matching code. When you pass 98074 then the service does not know which country you prefer.

Best Regards
