Can certified mail be used for international shipments?

Certified mail is a service offered by USPS that provides proof of mailing and delivery. However, it is specifically designed for domestic mail within the United States. For international shipments, certified mail is not available, which means that it cannot be used for sending items outside of the U.S. This is primarily due to the different postal systems and regulations in place in other countries, which do not align with the certified mail service provided domestically.

For international shipments, there are alternative services offered by USPS that can provide tracking and proof of delivery, but they do not fall under the certified mail category. Options such as registered mail or international tracking services may serve similar purposes, but they require different forms and procedures.
