Get ISO 3166-2 Code from Bing Maps Locations API

Question

Is there a way to get the ISO 3166-2 Code for a specific PostalCode/CountryCode Combination with the Bing Maps Locations API?

Per Example: 1210/AT => AT-9

Answer 1

Use the Bing Maps REST Location API and geocode your query (postal, country...). As part of the request add &incl=ciso2 which will return the country's ISO2 code value. For example:

https://dev.virtualearth.net/REST/v1/Locations?q=1210%2C%20AT&incl=ciso2&key=YOUR_Bing_Maps_Key

Will return the following:

Documentation on the Bing Maps REST Locaiton API can be found here: https://msdn.microsoft.com/en-US/library/ff701711.aspx

There is a best practices guide here: https://msdn.microsoft.com/en-us/library/dn894107.aspx

If using .NET you may want to use the Bing Maps REST .NET Toolkit: https://github.com/Microsoft/BingMapsRESTToolkit It makes it really easy to use the REST services in .NET and also has a NuGet package for easily including in your project.
