Certain ISO country codes not recognized

Question

If I submit a query consisting of "countryRegion=FR", I get a successful geocoding result for France. But if I submit "countryRegion=AX", where AX is the ISO code for Åland Islands, I get an empty response. Are only a subset of ISO codes supported? If so, where do I find the list of supported codes?

Thanks,

Adrian

Answer 1

Åland Islands is not a country, but a region/province of Finland. So this is likely part of the issue. The full list of ISO-2 values are not supported, only those that belong to officially assigned countries. Note that the complete ISO-2 list includes a mix of countries, territories, and areas of geographical interest

Thanks, Ricky. I thought that was probably the case, but it's helpful to have it confirmed.

Sorry to unmark your reply as an answer; it's just that I found another example. If I submit "countryRegion=BI", where BI is the country code for Burundi, I again get no results, although as far as I know Burundi is generally recognized as a country. But if I submit "q=Burundi" I get a result, and it includes the element <CountryRegionIso2>BI</CountryRegionIso2>. So what value should I submit for "countryRegion" if I want the service to return Burundi? 

Answer 3

Not every country ISO2 is supported. Only the more commonly used ones are. There are several reasons for this, primarily relevance.
