Global Security and Investigations

The U.S. Postal Service handles approximately 40% of the world’s total mail volume, including mail sent between the U.S. and other countries. The Postal Inspection Service’s Global Security and Investigations (GSI) office is critical to ensuring that the sanctity of that mail is not hindered by national borders. The GIS is responsible for protecting U.S. mail (military and diplomatic) that moves between foreign postal administrations and U.S. installations overseas as well as securing postal revenues generated by international business development. To do this, the GSI serves as a liaison between the Postal Inspection Service and a variety of international organizations, including the Universal Postal Union.
