DPD provides a Supported Countries list where you can set which countries can and cannot purchase from your store. To get to this page:
- Select either Tax Rules or Shipping from the left menu of your DPD dashboard
- Select the Edit Supported Countries button from the top right of the page as shown below:
From here you can disable, enable, or give a priority status to any of the available country options. Giving a Priority status makes that country float to the top of the country chooser in the cart. Disabling a country removes it from the country chooser in the cart, and enabling a country will have it appear in the chooser. Be sure to save to have any changes apply.
*Note: For these rules to apply you must collect shipping in your cart. You can toggle this option from Preferences via the left menu.
