title: How to get IAP country/state code (in order to know the VAT rate)?
body: <p>In order to calculate fair prices for paid app content, if the customer takes an auto-renewal subscription to access application content via In-App Purchases (IAP),  we need to know the VAT rate that applies to the particular IAP transaction.</p>
  <p>As far as I know, an app can only find the currency of the user's Apple ID, using IAP APIs.</p>
  <p>Is there a way to get to the country/state code, from transaction info (i.e transaction_id or original_transaction_id) on either (app- or server-side) or iOS APIs?</p>
