Can signature confirmation be added to international items?

Signature confirmation cannot be added to international items because international mail services have different protocols and tracking capabilities compared to domestic services. While signature confirmation is widely available for domestic parcels to ensure secure delivery, international shipments may not provide the same level of service due to varying regulations and practices in different countries. Additionally, many foreign postal systems do not have the mechanisms in place to obtain or document a signature upon delivery, making it impractical to offer this service for international items. Understanding these operational and regulatory differences is crucial for accurate shipping and customer communication.
