- Here's how to add international shipping to your listings:

On your listing, choose Show international services and options and select Save.
Choose Flat Rate or Calculated. A flat rate means you choose a shipping cost. Calculated shipping is determined by the buyer's location using US postal service pricing.
Select the countries you'll ship to from Destination, and choose your preferred shipping carrier from Service.
