If you are prompted to upload your passport after placing an international order, first take a photo of your passport that clearly shows both your photo AND your signature. Please note that for some countries, photo ID and signature are on two different pages, and you will need to include both. Then upload the photo you took on the order confirmation page that appears immediately after you book a shipment, or add it anytime later through your account.
