    Hi Gurupreet,

    Depending on which country you're working in, you should be able to use the Forward GeoCoder to find the locations of each postcode as LatLon objects. You can then use the LatLon.DistanceTo method to return the distance between the two locations, the distance units of your choice.

    You can find documentation on our GeoCoding functionality in the GeoBase SDK help, and you may want to investigate our provided sample, WebService, for an example of how to set up an ASP.NET webservice using GeoBase.

    Let me know if you need any further assistance.

    Thanks,

    Alex
